On a quick skim, at least, it looks like what you're doing is correct, and 
the relationship is somehow getting enchanted at the child class as well as 
the parent class, but only half-right down at the child.  I'd have to play 
with it a bit more to be sure, but I'm pretty sure you're running across a 
bug.

add_address should be picking up Party.add_address, which should be 
referencing party_oid=.  It looks like there's a 
PersonalCustomer.add_address, through, which there shouldn't be.

That said, I suspect you could work around it by doing this on Address:

  def personal_customer_oid
    self.party_oid
  end
  def personal_customer_oid=(oid)
    self.party_oid = oid
  end

(Which is a gross hack, but it'd be interesting at least to know if it 
works.)

Yes, that did work. Not pretty, but it moves me forwards.

The RSS feed content is URL encoded and doesn't have a very good
title. That's all I've noticed.

Congrats George!

FYI, I like the theme in the examples blog better than this overdone  
round blue theme :)

Also, what's your deployment look like (Webrick, FastCGI, ?)?  Did  
you have a look at the FCGI problem I had with web services?  If I  
could get around that issue, you'd not be the only blog running on  
Nitro/Og...

I have another error that appears to rooted in the same problem as I
previously reported.
  
As before I have Party, Person and PersonalCustomer. where Party
:has_many, Address
  
  I have saved a PersonalCustomer and now try to add multiple addresses. 
  I get an error when trying to retrieve an address by name.
  
  Here's the code that fails:
  
  def test_multiple_addresses
    p2 = CRM::PersonalCustomer.one :condition => 'customer_number=1002'
    p2.add_address( @a_primary )
    p2.add_address( @a_maling )
    p2.save

    p3 = CRM::PersonalCustomer.one :condition => 'customer_number=1002'
    a1 = p3.addresses['primary']
  end

   Here's the message I get:
   
DEBUG: SELECT * FROM ogcrm_personalcustomer WHERE customer_number=1002
DEBUG: SELECT * FROM ogcrm_address WHERE personal_customer_oid = 1
/usr/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.1.0/lib/sqlite3/errors.rb:94:in

Oh, it is FULLY themable :)

The blog runs using Webrick, Og in thread safe mode, output caching is
enabled, and an Apache server handles the static files.

The fix will be available in 0.22.0 but I 'll probably release some
preview gems in the next days, stay tuned!

regards,
George.

Subject: [Nitro] Controller not being picked up by dispatcher
Message-ID: <d10242550508020136444434b6@mail.gmail.com>

All,

Please can someone help with the follow (extraordinarily) simple
problem: my controller isn't being recognised, what's wrong?

---8<--- run.rb
#!/usr/bin/env ruby
require 'nitro'
require 'src/controller'

STDERR.sync = true if not STDERR.sync

# $DBG = true

include Nitro

Nitro.run do |conf|
  conf.dispatcher = Dispatcher.new(
     '/book' => BookController
  )

  conf.set(
    :name => 'Pendleton House Library',
    :host => '127.0.0.1',
    :port => 9999
  )
end
---8<---

---8<--- controller.rb
require 'nitro/controller'

include Nitro

class BookController < Controller
  # should use the default index method
  def search
    puts "BookController.search"
  end
end
---8<---

---8<--- index.xhtml
<?xml version="1.0"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
                      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
  <body>
  <a href="/book/search">Search</a>
  </body>
</html>

---8<---

The output I get on the console is:
---8<--- (stdout)

My guess is that there is something wrong with the dispatcher
configuration but I can't work out what it is. I haven't defined a
dispatcher for '/' as I was expecting that to pick up
/public/index.xhtml and render that. As it is, it looks like attempts
to render '/book/search' are being dispatched to the default
SimpleController and not my BookController.

Any help much appreciated.

First of all, you should update to the latest version of Nitro 0.21.2
Then I would suggest that you have a look at the intialization code in

examples/blog/run.rb

Uou should probably add something like:

Server.map = {
  '/book' => BookController,
  '/api' => ApiController
  ..
}
Nitro.run

If you still have problems let me know!

Message-ID: <d10242550508020847ba4e8bd@mail.gmail.com>

Hi All,

I've been working through the Nitro tutorial at NitroHQ and have a
question based on section
"Chapter 7: Shaping Up" http://www.nitrohq.com/view/NSBS_Shaping_Things_Up.

The tutorial states:
"...The form action is set to "post_entry," so you'll need to add some
server code to respond to that request ... First, Nitro will look for
post_entry.html. If not found, then post_entry.xhtml is the target. If
that does not exist, Nitro will attempt to invoke post_entry on the
default component..."

This is all perfectly logical and it what I would expect. However, the
text then goes on to say:
"...Finally, add a new template (named post_entry.xhtml to map to the
method) to render the new entry..."

My question then is this: if the dispatch sequence for requests looks
for .xhtml templates *ahead* of the controllers (first quote),
wouldn't adding the .xhtml template "to render the results of the
request" (second quote) short-circuit the process and prevent the
dispatcher from using the controller?

It would help me enormously if someone could describe the whole
decision chain from when a request is received until the response is
returned. E.g.

1. Server: request received
2. Server: apply request filters...
3. Dispatcher: find controller
    3.1 .html? ...
         3.1.1 html controller (SimpleController)
         ...
    3.2 .xhtml
         3.2.1 xhtml controller (SimpleController? Compiler?)
         ...
    3.3 Server.map[request url fragment #1]? 
          3.3.1 Controller: has method matching request url fragment #2? 
 etc.

Obviously a UML sequence diagram would be superb but a description at
the very least would help. I'm more then happy to sketch up the
diagram if someone can explain how it works. I'll try walking through
the code to get at the answer to this but if someone has a ready
explanation, I'm all ears.

Thanks,
Marcus

yes! webrick will answer to all requests for dynamic pages, which will 
be cached for future requests (as static html pages). apache will serve 
all requests for static files (media and cached html pages).

I am also walking through the code trying to figure this all out,
with the disadvantage that I am also new to Ruby so the code is a
little foreign to my eyes :(  At this stage, before my mental map
of Ruby has had a chance to settle in comfortably, all those nice
Ruby features that make programming faster and easier are just
making the code that much harder for me to read.  In the mean time...

If (when?) some kind soul does clarify the sequence above, could
you also explain how the system maps from the handling method back
to the choice of which template file to use?

It seems like just a *tiny* bit of hand holding documentation like
this would make all the difference for us Nitro newcomers/evaluators.

What is the prefered way of handling compound keys, compound
foreign keys, and compound indexes using Og?  I have read the
tutorials and looked at examples, but they all seem to only
handle simple databases like you would use to support a blog,
rather than more complex schemas such as you would find in
financial applications.

ActiveRecord also seems to have this limitation (at least
from the documentation I could find) and that is what made
me start looking at Og, to see if it addresses this scope.

I think I remember hearing that Og support for composite primary keys

on the web site or the parts of the source that I read.  Is there any
status / eta available?

I guess I might as well ask while I'm at it, does anyone know of a
viable / non-abandoned ORM that can use composite primary keys, can
work with Oracle (even if I have to write the code for it), and can
work with Nitro or Rails?

Hello Marcus,

For more details on this check out the file lib/nitro/compiler.rb
(#compile_action).
Process goes more or less like this:

You get a request uri in the following general format:

http://www.site.com/controller/action.

First the Dispatcher uses the the controller part to select the
appropriate controller. This controller  acts as the Render from now
on.

The the action part of the uri is extracted. The Render tries to call
the method "#{action}_action"
If the method does not exists the Compiler kicks in an tries to
generate the method.

The body of this method is built dynamically. If a method called
"#{action}" exists in the Controller it is called. Then if a template
called "#{action}.xhtml" exists in the Controllers template_root, it
is converted to a method called "#{action}_template" and then called
by "#{action}_action" after the call to "#{action}".

A lot of other things happen in the generated method, have a look at
the code for more details.

Hope this helps :)

regards,
George

Hello Tim,

How whould you like this to work? Can you give me a concrete example?
There is some support for compound keys in Og, and I plan to overhaul
the primary key issue in a forthcoming version, so if you could
provide an example this would better help me address the issue.

regards,
George.

But I want my own logic, not just a controller mapping. That's why I
want to specify the Dispatcher instance that is used like before, so I
can instansiate my own class. :P

well,

do it like this:

server.dispatcher = MyDispatcher.new 

but i think the Nitro.run/Server.run helper is not very ..helpful then
:) I 'll improve this.

How does one set the a user-defined primary key now? It should be as
simple as setting that to to an array of keys instead of a singe key.
And the rest should be automatic. I imagine that'll require some
simple improvements to the SQL generation code to take multiple keys
into account.

Sorry, I can't be more specific but I'm still too busy with other
things at the moment (i.e. Facets) to devel into Og any deeper.

I went and found the original post I was thinking of:
http://groups-beta.google.com/group/comp.lang.ruby/msg/e28b993a1b102c32

I read "fully customizable" and "use of existing schemas" and thought
there was already a design for composite keys just waiting to be
implemented.  (Probably because that's what I need.)

I'm not very familiar with Og yet, but I guess here's a pseudo API
proposal / example:

class Document
  property :volume, String
  property :accession, String
  property :path, String

  set_primary_key :volume, :accession

  has_many :pages, Page
end

class Page
  property :volume, String
  property :accession, String
  property :page, Fixnum
  property :skew, Float
  property :rotation, String
  property :status, String

  set_primary_key :volume, :accession, :page

  belongs_to :document, Document
end

That's pretty close to a subset of my real situation.  I'm thinking
there is going to be a problem with schema creation.  Does Og

Most of the infrastructure to do this is already in place. I 'll
rework the missing details for the next version.

yeah, add an :sql_constrain to your class, ie

meta :sql_constrain, 'your sql constrain here'

Hello!

I'm wondering how to build recursive database structures with Og. Like this:

  class Foo
    belongs_to parent, Foo
    has_many children, Foo
  end

  bar = Foo[1]
  bar.children.each do |child|
    # ..
  end

The problem is that then Og tries to SELECT * FROM ogfoo WHERE foo_oid
= 1. I think I've seen a solution on this list or somewhere, but I
can't find it.

At the moment you can do:

class Document
  property :volume, String
  property :accession, String
  property :path, String
  sql_index :volume, accession

  has_many :pages, Page

  def self.[](volume, accession)
     Document.find(:condition => "volume=#{volume} AND accession=#{accession}")
  end
end

then you can use the proposed api:

doc = Document[vol, acc]

Is this all you want? Some new features of 0.22.0 will make this much
more transparent.

regards,
George.

Hello,

In your case, you probably want to do:

def my_action
end
alias_action :index, :my_action

anyway, you are probably looking for:

def index
end
action :index, :view => 'your view...'

I should probably add a render template method though.

Hm, the problem is, that it always goes through the dispatcher. Or am I 
wrong? A template always needs an associated controller.

But I'd like for example to use a Page Element, which renders some 
templates. I just want to use template-files instead of embedding the 
HTML inside the Ruby code. But using <render href=""> does not work as 
expected, as it requires a mounted controller.

Hello,

I was following the nitro's tutorial, but got really stuck on the
following page :
http://www.nitrohq.com/view/NSBS_Page_Generation_with_Class

I'm supposed to be able to run the following code :
------
#!/usr/bin/env ruby

require 'nitro'
require 'feeds'

a = App.new
a.map['/feeds'] = Feeds
a.start
-----
Unfortunately, a.start doesn't launch webrick and no error appears.
My lib/feeds.rb is also ok I think.
I'm really stuck on this.


My environnement is Windows 2k with OneClickRubyInstaller v1.8.2-15.
The installed gems are :
facets (0.7.2)
fxri (0.3.2)
fxruby (1.2.6)
glue (0.21.2)
nitro (0.21.2)
og (0.21.2)
RedCloth (3.0.3)
ruby-breakpoint (0.5.0)
sources (0.0.1)

Do you have any idea what it could be ?

Subject: [Nitro] Og questions
Message-ID: <3ff63f9b05080507402fc3e21@mail.gmail.com>

Hello,

I have some stupid questions to ask about Og's functionning. I'm
really a newbie, and thus I'd understand that you don't loose your
time. But I'm also really excited and like to ask anyway.

 - Why do I have to tell the relations to Og ?
I've read that active-record uses a dictionnary to find singular and
plural terms. I'm wondering if it could be used to tell the relations
so that

def Post
  has_many :comments, Comment
end

def Comments
  belongs_to :post, Post
end

could become

def Post
  property :comments, Comment
end

def Comment
  property :post, Post
end

 - Is it possible to define customized data types and also can they
encapsulate validation ?
Depending of the field of application, you often have a set of data
types that you find everywhere. Typically in web forms. You'll have
the Password, the Country, the Email. Those types also have the same
validation rules all over the place. Maybe something like that :

def Email < String
  validate_value
  validate_length :range => 2..100, :msg_long => 'argh'
  validate_format :format => /[mysterious_regexp]/, :msg => 'wrong format'
end

def Author
  property :email, Email
end

a = Author.new
a.email = "user at tld.com"
a.email.valid? => true


That's all for today :-P

Greeting list,

I'm having the same problem as mentioned this morning in "Problem on Nitro's tutorial" (sorry, just joined the list a couple minutes ago, so I didn't have that email to reply to.  I'm using Ubuntu Hoary 5.04, and have nitro 0.21.2 installed from rubygems.  To make this easy to repro, I set up my example in a bash script.  My problem is the same as the OP's; when I try to start the app with run.tb, nothing happens.

Nitro is changing really fast, so the tutorial is a bit outdated. I
would suggest that you have a look at the blog example, or at the
source code for Spark.

No in AR you have to use belongs_to, etc as well.
BTW, Og also uses the inflector so that you can say:

belongs_to Comment

instead of 

belongs_to :comments, Comment

never actually tried that, but most probably it should work :) Try it!
In any case I 'll check this.

As I said have a look at the examples. Your code should be like this:

require 'nitro'
require 'feeds'

Nitro.run(Feeds)

there are alternative ways to do this, but this should get you started.

I'm inclined to do the same for Facets. I don't see why it should be a
problem. On the other hand I've cautiously moving toward including
tests in with the code itself, i.e.

  # code
  ...

  require 'test/unit' if $0= __FILE__
  
  # test
  ...

This may not be a viable solution for a web-engine like nitro, but it
seems to work find for extensions. Any comments/caveats to this
approach?

T.

P.S. Perhaps I should foward this discussion to ruby-talk?

I think I've mentioned this on ruby-talk before, but my group likes to
combine code and dependencies into a single file.  Aside from greatly
simplifying delivery, we've seen surprisingly large runtime benefits.

The $0 == __FILE__ convention makes writing a program to do the
bundling a lot more complicated.

Of course, it's already popular enough that I wouldn't blame you for

P.S. There was a thread about adding a TEST{} block like BEGIN{} and
END{}, if you can find that you'll get a good overview.

Something to be aware of: this way of running the application will map
the Feeds controller to the root URL fragment. I've made a stab at
updating the tutorial section to use working code.

I have something like this:

class Foo
	has_many :bars

	def sna
		bars << Bar.new
	end
end

It complains that there is no bars.  I've dug around, and I've not been able to figure out what methods the 'has_many' provides.  What's the right way to add a Bar to a Foo in this case?

Logic tells me I need to initialize an "@bars = []", (and that does make the immediate problems go away), but I can find no example that shows that.  Does has_many also provide 'accessors'?

What support already exists in Og to support unit-testing that persistent

Subject: [Nitro] [ANN] Nitro + Og 0.22.0
Message-ID: <afd80b5405080711541225fc2@mail.gmail.com>

Hello everyone,

New versions of Nitro (Web Application Framework) and Og (Object
Relational Mapping) were released:

Homepage: http://www.nitrohq.com
Download: http://rubyforge.org/projects/ nitro
Mailing List: http://rubyforge.org/mailman/l istinfo/nitro-general

A snapshot of the latest developments. Many requested features
where implemented, and many reported bugs fixed.

* The much requested Og 'reverse mode' is implemented. Og's
domain specific language and API is extended to allow fine-grained
customization of the schema-to-objects mapping. Og can now handle
most of the legacy schemas you can throw at it. Here is an
example:

class User
  property :name, String, :field => :thename, :uniq => true
  property :password, String
  property :age, Fixnum, :field => :age3
  has_many Comment, :foreign_field => :user
  set_table :my_users
  set_primary_key :name, String
end

class Comment
  property :cid, Fixnum
  property :body, String
  belongs_to User, :field => :user
  set_table :my_comments
  set_primary_key :cid
end

As you can see, even relation fields can be customized. For
higher level customization you can overload methods like #table,
#field_for_property etc.

* Og now handles multiple connections to multiple stores even
in thread safe mode. This means you can now have objects serialized
in different RDBM systems in the same application. Or you can have
some objects managed by an RDBMS store and others by a FAST
in-memory store. You can still have relations between objects in
different stores. An example:

mysql = Og.setup(:store => :mysql, ..)
psql = Og.setup(:store => :psql, ..)

class User
  has_many Comment
end

class Comment
  belongs_to User
end

mysql.manage_class User
psql.manage_class Comment

user.comments << comment

* Greatly improved support for testing and test-driven-development.
A reworked testing infrastructure for controllers is in place.
Moreover, support for Og fixtures and automatic test database
setup is provided. Fixtures can be defined with yml or csv files.

For an example of the testing infrastructure check out the
Spark 0.4.0 sources. Spark is a Wiki powered by Nitro.

* Reworked mailer implementation. The new mailer allows for
incoming email handling. Here is an example:

class Mailman < Glue::Mailer
        def receive(mail)
                article = Article.new(mail.subject, mail.body)
                article.category =
Category.find_by_name(mail.to.split('@').first)
                article.save
        end
end

* Added script/runner in proto as a convenience to running
ruby code in your application environment.

* Many fixes in the caching infrastructure.

* Many fixes in the XMLRPC service infrastructure.

* Many smaller changes and new features that make
development with Nitro so much more pleasurable.

Nitro provides everything you need to develop professional Web
applications using Ruby and Javascript.

Nitro redefines Rapid Application Development by providing a
clean, yet efficient API, a layer of domain specific languages
implemented on top of Ruby and the most powerful and elegant
object relational mapping solution available everywhere.

have fun,

Is there documentation about what makes these available? (Also, I'm a bit

Not what I'm looking for.  I want to be able to assert that particular objects 
were 'saved', without actually having a persistence service.  I want to be 
able to arrange for particular objects to be returned for various 'queries'. 

 (A traditional (in my mind) mock persistence layer).

The source code. But here's the beginning of something which might 
become Og API walkthrough.

  http://www.cs.helsinki.fi/u/kaniemel/walkthrough.txt

I've posted it before on the list. In it I explain how Relations (like 
HasMany) get the keyword (like has_many) and how they're initialized. 
This is not real documentation, but might shed some light to the dark 
corners.

I'm not sure if this is new in 22, but I'm getting the following stack trace:

/usr/lib/ruby/gems/1.8/gems/og-0.22.0/lib/og/relation/has_many.rb:24:in

`manage_classes'
	from /usr/lib/ruby/gems/1.8/gems/og-0.22.0/lib/og.rb:157:in `setup'

I've looked through the code, and it appears that target_class is nil.  I've 
looked, and I can't find anywhere target_class is defined anywhere.  In fact, 
I'd expect to get the "undefined local variable or method" error.

Help.

This is very good. Using what you call 'reverse mode' I am able to
work in a more natural (for me, at least) way. I still need to use
Aleksi's hack to get around the inheritance issue, but I have enough
working that I can move ahead.

Thanks for the good work.

Show my in (pseudo)code what you want. I think it will probably

See the class Address. Comment out tthe two personal_customer_oid,
personal_customer_oid= methods and the code fails.  This is code was
updated to use Og 0.22. Tell me if I am using it incorrectly.

hi,
i'm trying to og my legacy tables with the new reverse feature:

class Person
	property :id, Fixnum
	property :title, String
	property :fname, String
	property :lname, String
...
	set_table :efa_persons
	set_primary_key :id
	has_many Note
	belongs_to Company, :field=>:company_id
end

p=Person[1]  # thats me

# sql ist right but it
# gives me an error:

DEBUG: SELECT * FROM efa_persons WHERE id=1
/usr/lib/ruby/1.8/yaml.rb:119:in `load': parse error on line 0, col
19: `t/string/unix_ ' (ArgumentError)
        from /usr/lib/ruby/1.8/yaml.rb:119:in `load'
        from (eval):4:in `og_read'

        from ogtest.rb:31

alternative:

t=db.load(1, Person)

gives

ogtest.rb:30: private method `load' called for
#<Og::Manager:0xb7ccdc10> (NoMethodError)

anybody knows whats wrong?

thanks,

Thanks a lot. That's exactly what I needed. You dont't want to put this 
in the wiki?

Whatever you call that, code walkthrough, concepts or big picture... I 
wish someone who can distingish about the current Nitro development and 
deprecated modules and classes would set up a skeleton (format like the

i got something, that works for me:

entity.rb:

   def set_sequence(seq)
      meta :sequence, seq
    end


store/psql:

  def enchant(klass, manager)
    if klass.metadata.sequence
      klass.const_set 'OGSEQ', klass.metadata.sequence.to_s
    else
        if sclass = klass.metadata.superclass
          klass.const_set 'OGSEQ', "#{table(sclass.first)}_oid_seq"
        else
            klass.const_set 'OGSEQ', "#{table(klass)}_oid_seq"
        end
    end

    if klass.metadata.primary_key.flatten.first == :oid
      unless klass.properties.find { |p| p.symbol == :oid }
        klass.property :oid, Fixnum, :sql => 'serial PRIMARY KEY'
      end
    end
    super
  end

No, this give the error I reported earlier:
(eval):23:in `add_address': undefined method `personal_customer_oid='
 for #<Address:0xb7c5c46c> (NoMethodError)
    from og-test.rb:53:in `addAddress'
    from og-test.rb:124

Right now, I am getting along using the hack suggested by Aleksi
(adding personal_customer_oid, and personal_customer_oid= methods),
but it is not a working solution when I have many derived classes.

Hi George,

I'm having a problem importing the structure from a legacy MySQL DB
into a PostgreSQL one.
The problem is with the pre-defined 'oid' field: in MySQL it's
'auto_increment' and in PostgreSQL it's 'serial'. Is there an elegant
way to convert the values?

Or, do I need to comment-out the 'unless' clause (leaving, of course,
the klass.property assignment)? I.e., is there a really good reason to
preserve any pre-defined oid definition?

Thanks,

- Dimitri

Message-ID: <42FB6A7A.1060106@ond.vein.hu>

Hi,

admittedly I started to play with Og today so please feel free to correct me 
with anything (or just send over /dev/null :), but I'd like to share my 
experiences and ask for suggestions. All my experiments happened on my gentoo 
linux box, Og installed by gem, version 0.22.0 on ruby 1.8.2.

The first problem I bumped into can be demonstrated with the following piece of 
code:

running this script dumps this error:
/test_og.rb:15: undefined method `belongs_to' for LineItem:Class (NoMethodError)

I kept on fighting and after some time I realized that adding any property to 
LineItem before the belongs_to declaration fixes the problem. Is there any other 
way to trigger initializing Og (I think that's what fails to happen in this 
case) than this?


Next I had set up an unidirectional many-to-many relationship. I tried very hard 
to set it up correctly and get the join table generated, right until I realized 
that it IS generated just not in the logs.. (the two other create table sql 
statements were displayed as INFO messages but not the join table :) Do you 
think it would make sense displaying that info as well?

Still at the many-to-many relationship (example was many SoftwarePackage can 
contain many Software), I tried to create a constructor for SoftwarePackage 
which accepted an array of Software (simplifying the example here):

----
class Software
   property :name, String
end

class SoftwarePackage < Software
   many_to_many :software, Software

   def initialize(software)
     software.each { |x| add_software x }
   end
end
----

and well, it did not really work out. I find out that I have to call save first 
in the SoftwarePackage constructor, else an invalid sql will be generated like:

INSERT INTO j_software_softwarepackage (software_oid,softwarepackage_oid) VALUES 
(1, )

with a missing id. Again, I've got a workaround here so I'm not sure if that's 
the way it's meant to work or that's clarified as a rough edge and you plan to 
smooth it a bit :) Still at this topic slightly against following the least 
surprise principle first I assumed the following line to work in the constructor:

software.each { |x| @software << x }

Maybe it would be nice to have that too if possible.


As a last question, is there a way to change the oid naming strategy followed by 
Og? A similar approach as setting Og.table_prefix = nil would be really useful.

Wrapping up, I'm absolutely amazed with the power of Og. I'm actually sketching 
a new java project's software design from scratch with ruby and Og (first time 
attempting this), and I'm blown away with the speed I could build/test and play 
around with my domain objects using Og.

Thanks much, and keep up the excellent work,

I notice that when I attempt to run the unit tests on Og 0.22.0, I get
this error message:

I checked the generated sql and, sure enough it is attempting to
create a column 'oid' as primary key three times. The behaviour is
specific to schema_inheritance.

you can use either:

class MyObject < Og::Entity
..
end

or

class MyObject # so you can still inherit from another class
  include Og::EntityMixin
  ..
end

as a shortcut, if you define a property, the Mixin is automatically included.

A feature that will make this possible is planned for the next version
(in-memory
building of collections). However, if someone cares to provide an
implementation for this please feel free to submit a patch.

> As a last question, is there a way to change the oid naming strategy followed by

you can use either

class MyObject
  property :mykey, String, :primary_key => true
  ..
end

or (prefered)

class MyObject
  propety :mykey, String
  ...
  set_primary_key :mykey, String
end
 

> Thanks much, and keep up the excellent work,

Hope you will be able to help this project too :) We need all the help
we can get.

Hello John,

The Og unit tests need some refactoring to work through rake. I am
running them one after the other and everything works. I hope a member
of the community can step in and help with the refactoring of the unit
tests.

A related effort was started by Aleksi, and to facilitate this,
improves support for Og testing was added in the latest version. If
anyone has got some time this would be a good project to work on.

regards,
George.

There's patch for this functionality already. But I'm not sure if George 
ended up adding a new keyword just to enchant the class with relation 
macros. Refer to

  http://rubyforge.org/pipermail/nitro-general/2005-June/000448.html

if you want to implement it by yourself.

Sure. Here's the patch. I wasn't able to test it but doesn't seem 
complicated enough to really break anything, and I'm sure George will 
test it before commiting.

The example at the end of this mail works for me. So perhaps you can

I've used it last year, for a small university project. It's *very* easy 
to setup. Commands are a little bit different if you come from CVS/svn, 
but it's easy to learn. Nice is that you can view every diff or only 
apply partially diffs, so for example you can hack a new prototyp and 
then selectively commit only parts of the changes to the repository. I 
missed that feature serveral times in subversion/CVS, where you can only 
commit all at once or selected files.

I don't know whether darcs can 'move' modified files. Subversion can't. 
  Sometimes you need to move a file and make a change. That has to be 
split across two commit, which is not very nice. And CVS can't even 
rename ;-)

But I never tried Darcs with multiple users.

Then I tried to maintain configuration files with Darcs and realized 
that it does not handle permissions. For this task it's not suited.

In total, mostly positive experience (except the long build duration of 
Haskell GHC ;-). My feeling is that Darcs is much more mature than 
subversion.

Regards,

   Michael

Subject: [Nitro] Og and derived classes...
Message-ID: <42FBF504.7030309@cataclysm-software.net>

I'm trying to write some code that stores ruby classes, modules and 
methods. A class can contain both a module and methods, a method can 
also contain methods. In my code classes are a derived class of methods, 
and I've set the has_many to be methods for the module class. The method 
class has belongs_to set to be a module...

However og doesn't seem to like this idea much, is this kinda 
arrangement even possible? It seems that og isn't smart enough to notice 
that class is derived from module.

Here's my stripped down example of what I'm trying to do:

============================

require 'rubygems'
require_gem 'og'

#turn on debugging
$DBG = true

class Doc
     property :name, String

     def initialize(name)
         @name = name
     end
end

class DocModule < Doc
     has_many :functions, DocMethod #contains many methods
end

class DocClass < DocModule
     many_to_many :modules, DocModule #may have many modules, and those 
modules may be in other classes
end

class DocMethod < Doc
     belongs_to :parent, DocModule #belong to a DocModule as DocClass is 
a subclass of DocModule
end

db = Og.setup(
       :store => 'mysql',
       :name => 'test',
       :user => 'bleh',
       :password => 'something'
)

testclass = DocClass.new('Testd')
testmethod = DocMethod.new('test')
testmodule = DocModule.new('module')

testmethod.parent = testclass

#save the objects

testclass.save
testmethod.save

#this works
testmethod.parent = testclass

#but reports no parents...
puts testmethod.parent

#this causes a crash
#testclass.add_function(testmethod)

#this causes a crash
#puts testclass.functions

===============================

I'm also having problems using a filesys store, are there any tips on 
that, developing on a mysql db is a bit annoying as I have to keep 
manually deleting the tables when I mess with the structre. I thought 
Og.create_schema = true would help with that, but apparently it does not..

I really like the idea of og, and really want to use it and nitro, great 
job so far (tho the docs could be better).

Here's a couple of tips:

use something like:

db = Og.setup(
      :destroy => true,
      :store => 'sqlite',
      :name => 'andrew'
)
This re-creates your database each time. Note that I use sqlite3 --
it's good for this sort of work.

What error message do you get when your test crashes? Maybe it is
related to the problem I reported?

John,

It does indeed seem to be similar to your problem, when I do:

testclass.add_function(testmethod)

I get:

(eval):23:in `add_function': undefined method `doc_class_oid=' for 
#<DocMethod:0xb7a4bd2c> (NoMethodError)

and if I do:

puts testclass.functions

it errors out with:
ERROR: DB error Unknown column 'doc_class_oid' in 'where clause', 
[SELECT * FROM ogdocmethod WHERE doc_class_oid = 1]

I get similar errors doing a add_function using a DocModule. but 
strangely if I do:

testmodule.save

testmethod.parent = testclass

puts testmethod.parent.inspect

It looks like its assigning testmodule as the parent, not testclass...

Very bizarre.

Oh, destroy => true was just what I needed, thanks.

Andrew

Hi George & Aleksi,

thanks much for your help, it's always a pleasure to meet a very friendly and 
responsive community :)

I hope the patch about displaying the join table makes its way into the next 
release. It's a minor (ok, a trivial) issue, but I seriously spend over 10 mins 
trying to 'fix' my relation setup before realized what was going on..

There's one issue you did not response to: about using the @entities << entity 
syntax at many-to-many relationships. I'd absolutely prefer that to using the 
add_entity() method.

Aleksi, thanks for cleaning up my testcase :) I applied the same workaround 
(saving the collection in the initalize method before adding related objects), 
it works fine for now..

George, I'm not sure what (or how much) I could help you with the project. My 
freetime is another term I could hardly define... ;)

I'm basically a java dev who heard the noise on Rails some months ago and some 
weeks later realized the beauty and power of Ruby.. On the other side I could 
never accept the AR approach about thinking about the database. I prefer OO 
design and use a relational store only to persist. Therefore Og fits me 
perfectly sketching the design, writing a couple of testcases verifying domain 
logic and I get the DB schema for free (yeah Hibernate gives me that too but Og 
running my tests in 0.2s on my developer box can hardly be beaten with anything 
java ;)

I'm still trying to wrap my poor little brain around the templating 
stuff.  Looking at Spark 0.4.0, do the <Page> tags in the template/ 
xhtml files directly refer to the fact that the skin.rb class is a 
subclass of the Element class?

"class Page < Nitro::Element"

Andrew

I have been experimenting with a patch in HasMany#enchant

#    self[:foreign_key] = "#{foreign_name ||
owner_singular_name}_#{owner_pk}"  #original

    self[:foreign_key] = "#{foreign_field ||
owner_singular_name}_#{owner_pk}"  # *** hack ***

This actually fixes my problem and doesn't appear to break any of the
unit tests I have run. Alas, it has no effect on the many_to_many side
of things. For that a deeper solution is needed. I hope George gets
around to fixing it.

Yeah, if you define a subclass of Nitro::Element you can use it in
your tempates as a cheap form of macro or tag.

class MyTag < Nitro::Element
end

responds to 

<MyTag>...</MyTag>

or

<x:my_tag>...<x:/my_tag>

to be xhtml compliant

you can customize the x: prefix if you want.

George.

I look forward to it, I really really like the ideas behind og/nitro and 
can't wait to write something using them, I guess I'll just dump to YAML 
for the moment until you fix og.

Thanks

I agree. I generally won;t touch CVS unless I have to. Rubyforge now
supports SVN, yes? Sure would like them to add Darcs though.

Subject: [Nitro] Og 1-n relation alias bug
Message-ID: <42FE87A5.7000600@ond.vein.hu>

Hello guys,

I think I've got something real bad for you this time. Consider the
following testcase:

------
#!/usr/bin/ruby -rubygems
$DBG = true

require 'og'
require 'test/unit'

class Book
  include Og::EntityMixin
  property :title
  belongs_to :owner, Person
end

class Person
  include Og::EntityMixin
  property :name, Og::VarChar(128)
  has_many :books, Book
end

class TestOg < Test::Unit::TestCase
  include Og

  def test_basic
    book = Book.create
    person = Person.create
    person.books << book    # blows here
  end


  def setup
    Og.table_prefix = nil
    og = Og.setup(:store => :memory, :name => 'test')
  end
end
------

At the marked line the relationships blows with the message:
NoMethodError: undefined method `person_oid=' for #<Book:0xb7b38600 @oid=1>

Now I gave it some time and try to dig down to the root of the problem
to a be bit more help now just whine here ;) Unfortunately all I could
find out is that around that has_many.rb uses a slighly naive-looking
approach at setting up the collection's options. 'foreign_name' is not
set at all so foreign_key is made up of owner_singular_name which does
not care much about the alias set up for the collection. No wonder the
whole thing crashes then on the enchanted add_stuff method :(

As a side note, eg. for refers_to the foreign_key is filled according to
my added logs but I still could not find where it was set from, some
black magic might be happening here.. :)


George, while you're into it, please try to delete any of the plain
properties from the classes defined above and rerun the test. It dies
for me with:

NoMethodError: undefined method `store' for nil:NilClass

The very same happens when trying to define the Og::Entity superclass
instead of the mixin..

cheers,

Kristof

Hi all,

I finally had the opportunaty to work half-way through the tutorial and 
I'm looking forward for my own 20-30 mins a day nitro development. One 
thing that I'd really need is the standard user registration per email, 
i.e. user  registers with user name, email and password, gets an email 
with a link she has to click to become authorized to enter the site.

Does this funcitionality already exist? Or will nitro-auth cover it soon?

Thanks! - Bernd

Hello and welcome to the list,

the functionality is out of scope for Nitro. Nitro is a 'low' level
framework. However, I expect spinoff projects to provide this
functionality. Nitro-auth is a likely candidate.

Hello Kristof, 

thanks for the report, here is a workaround till this situation is improved:

class Book
	property :title
	belongs_to :owner, Person # this creates a problem?
end

class Person
	property :name, Og::VarChar(128)
	has_many :books, Book, :foreign_name => :owner
end

Well you cannot create an opject w/o properties. Perhaps a better
error message is needed though.

OK. Can anyone tell me how good or bad nitro-auth integrates into Nitro?

If I would be more experienced with Ruby (just started about two months 
ago) I would
probably try to add that to nitro-auth myself. I just don't want to 
introduce bad design
and code to the nitro projects.

I believe handling authentication and the registering process is one the 
most important
functionalites / services a web framework has to have. In my case I 
would like to avoid
paying bandwith, CPU, IO, etc.  for robots / spammers while opening 
doors to increase the
data quality of the event calendar I'm planing to implement with nitro.

I'm thinking about a half open system, where everyone can read data 
related to _one_
object (like a club)  by providing an additional key (hardcoded in the 
URL) while
every write or global read requires registration and authentication.

This way people could include dynamic services in their static webpages like
news boards, calendar information, etc.

We at Navel (my company) are working on a super-duper user/identity
system for our (Navel) internal high level framework. I 'll discuss
this with my partners, perhaps we can just release this single
component (part) as an example. But this will take a lonf time. I
would suggest that you work with Deborah to improve the existing
nitro-auth package.

regards,
George.

This is another variant of the same bug that Andrew and I have
reported earlier. We both receievd "NoMethodError: undefined method
`xxx_oid=" messages. In our cases, the bug was triggered by our
inheritance relationships. The root cause is the failure to use the
correct foreign_key value. I will check to see if setting foriegn_name
helps (I had been experimenting with fudging it in the has_many.rb
file)

I just finished the implementation for this in Rails ;-)
(and i've done one in Wee, too :))). So, it's not that hard to do in 
Nitro either ;-)

I've two tables: accounts and activation_ids. Accounts has a field 
active, which by default is false. When a user signs up for an account, 
the account is created (inserted into table accounts) but is inactive. 
Furthermore an entry is inserted into activation_ids, with a unique SHA1 
sum, which is sent out to the user by id. A controller 
/account/activate/"checksum" will then delete the corresponding 
activation_id and set the account.active to true.

Regards,

   Michael

Certainly it's within the scope of what I had in mind for nitro-auth.  I've 
not messed around with the auth stuff in the last week or two, been 
fiddling with low-level Og::Store stuffs.

I'm open to patches/tweaks/suggestions, though, definitely.

Well, it's written with the specific purpose of being an authentication 
system for Nitro, so I'd say it's designed to integrate pretty well. 
Whether it does or not on any given day might be up to more contention.  :)

If you'd like to send me suggested patches, I'm happy to review them and 
tweak/integrate.

One thing nitro-auth desperately needs is a reasonable unit test suite; I 
was struggling early on with figuring out how to reasonably unit test Nitro 
applications and I haven't gotten back to that.  (The Og::Store stuff I've 
been playing with has a really extensive suite of unit tests now.)

Hi Ysabel, hi Michael,

thanks a lot for taking care about this auth-stuff. As I said I don't 
feel experienced enough
to write good Ruby code and I don't know about the nitro-auth design. 
I'm looking for
something that works like the mechanism that Michael described.

I might do the task if noone else moves first. But that can take some 
time...

Thanks! - Bernd

I'm having trouble with primary keys and sequences in a legacy DB.
There seems to be a naming convention tha Og expects, something like
"oid" for the primary key, "<tablename>_oid" for foreign keys, and
"<tablename>_oid_seq" for sequences.

How do I override these names to match an existing database?

I've downloaded it and/or installed it, but haven't found motivation
to actually try it. I'm very wary of it being written in haskell. The
patch-based revision style is a bit of a paradigm shift, too.
Subversion works extremely well for me, so motivation is hard to come
by.

hi kevin,
currently only primary key and foreign key aliases are supported.
set_primary_key :name, :foreign_field
sequence aliases will come soon :)

george calls it the reverse mode.
look at: http://nitrohq.com/view/Release_notes

i think, to make og real powerful, there has to be done a few things in this 
direction. the concept of og is not to care at all at the db ddl. let
og do all the
work. in practice, i would say, that is simply impossible. fourther more, there
are many legacy apps that could be enhanced by ruby og scripts if it was the
'swiss knife' of OR libs.

what i'd like to see is a way to read the properties/
relationdeclares/ foreign-key
stuff per ogified class from an external file, that is quick to parse
like ini or yaml (NOT xml). i was pretty convinced once i saw, how
helma (http://helma.org/) handled that stuff with ini files. so i'm
doing so with a php OR class and i'm quite happy with it.
that could be quite useful to generate ddl from that files and vica versa....

just a few thoughts.
regards,
  robert

I have also downloaded and installed some time back, but didn't do
anything more than test it. Being written in Haskel is not in itself
an issue (as long as I don't have to modify it) but I didn't feel it
offered enough over Subversion and I didn't find any mention of an
Eclipse plugin. Most of my real work (the stuff they pay me to do)
uses the Eclipse IDE, so integration to Eclipse would be a major plus.

hi,
to be a bit more specific about the way to describe tables in an
external file. how do you like that way:

class Person
      look_at_file true
end

person.ini:

; autogenerated file - generator: generator.php
[table]
name=persons
sequence=persons_id_seq

[keys]
id=1

[fields]
; 1-number, 2-string, 3-date, 4-datetime, 5-blob
id=1
title=2
fname=2
lname=2
address1=2
address2=2
country=2
postalcode=2
city=2
phone=2
fax=2
mobile=2
email=2
web=2
company_id=1
creation=4
lastedit=4
version=1


[autodate]
created=creation
modified=lastedit

[autoinc]
version=1

[relations]
has_many=notes
belongs_to=company
company.fkey=company_id

If a file were to be used, then it should be a YAML file. YAML is
universal, INI files are more windows centric.

The descriptor-file design is NOT a good one. It's adding yet another
layer of duplicate information --far from DRY. The best way is either
the Og way or the ActiveRecord way. I.e. either the OO system
specifies the data structure, or the relational backend does. There's
no need for a third way to tell both of them how to be. Such systems
(and there are plenty) are a pain. And I like that Og will be able to
support the ActiveRecord way too; so it will have the best of both
worlds.

FYI, if you are concerned about SOC (Seperation of Concerns), I'm with
you. But that can be done in the OO system too. To do so in Og, simply
build your classes as normal (don't consider the DB), then afterward
create seperate modules to extend the classes with the porper DB
interface. This makes for a vry elegant and clean design (with only a
slight but worthy sacrifice to DRY) I've talked to George about this
and he knows it something to solidly support in Og.

T.

i disagree. of course the pure og way doesn't need that (in theory). but even
if you don't want to use it for existing tables you *should* give hints about
creating indexes and stuff. AR on the other side can't read every information 
as metadata from the db. think about foreign keys, that simply don't exist in 
mysql (myisam) tables. the question is: where is this information stored?
the classfile is quickly clustered with this stuff. so i like the
*option* for saving
that in an external file...

i agree, most *existing* systems are pain :)

this is what i have in mind. feel good with *one* API and use it everywhere

yes, that could be a way for the separation.

I'm sorry but I don't understand at all what it is that we'd gain from 
this representation? Why not simply use Ruby and Og and define the same?

In this case all above might not be possible with Og, yet, but something 
along lines:

class Person
  property :title, :fname, :lname, :address1, :address2, :country, 
:postalcode, :city, String
  property :phone, :fax, :mobile, :email, :web, String
  include Autodate
  include AutoInc
  autoinc :version
  has_many Notes
  belongs_to Company
end

There are or at least there will be ways to express foreign keys and 
indexes, as well as map names of fields and tables etc. There will be 
more useful parts (like autodate) for objects to be managed for 
persistence to include when needed. What's that special usefulness that 
your pure text version provides?

If you need this kind of definition to be somehow abstract, one should 
be able to write a text to Og Ruby code translator pretty easily and 
then one could convert the above text to above code for run-time 
evaluation without great pains.

So again I making a question what's this all for? What do we gain by 
adding an extra layer needing conversion?

What I can see that we're losing by using pure text (ini-file based or 
not) data definition mini-language is the ability to use 
turing-complete, working, easy, simple and useful full language to 
describe a bit more complex issues. And do so even without having text 
to code to datastructures conversion library source code, just by 
extending where Og left.

Should you need to write to logfile every time object's accessor is 
used, you're free to define your own "property" method for definition 
language inside Ruby. Not to mention Og already supports Aspect Oriented 
way to inject code.

your right. sorry. maybe you don't need it. it's just me the swinging man, who
thinks to need it. cause i'm switching environments that often needs conversion.
a simple to parse metafile is quite usefull ... and think of comparing
versions - every
line is a property...

this is a strong argument. but i thought of the textversion as an
*option*, then
as a subset (namely the most often used rdbms features) of
possibilities. and yes:
some converter should be easily done by myself :)

Message-ID: <4302CC43.8000308@bdebl.de>

*Hi all,

recently I went through the Nitro tutorial and updated a few things
to make it work again. Something I couldn't solve (and I tried to find
that stuff in the sources) is to make the code in
http://www.nitrohq.com/view/NSBS_Page_Generation_with_Class run.

undefined local variable or method `o' for #

I'm not sure if I made another error somewhere. Can someone with
a clue please check the tutorial. Since we have not so much
documentation at least the tutorial should be kept up to date to find
a wider audience for nitro.

Thanks! - Bernd

PS: If there is indeed an error just let me know what and I try to fix
it and update the tutorial accordingly.

Subject: [Nitro] Problem with controller arguments
Message-ID: <200508171940.28720.arcatan@gmail.com>

Hello!

I'm reimplementing my website in Nitro and I have a little problem. I have 
code like this:

class FooController < Nitro::Controller
  def view(foo, bar)
     # do some stuff
  end
end

Now, this works fine with urls like http://site/view/some/thing (foo="some", 
bar="thing"). But, I would like to have also urls like 
http://site/view/some/thing/nice, where foo = "some", bar = "thing/nice".

Is this possible?

Hi:

New to this stuff myself (Hello everyone - I've just joined the  
list), but I can't see
why you would want the entire remainder of the URL to get passed to  
the last variable?

request.uri

^ contains the whole uri string, could be some help?


Oo while I'm here: Apache and WebBrick return different URIs ...  
(apache will give a leading "/" )
would be good if this could be ironed out when request.uri gets built  
to allow greater
portability between design/production.

Out of curiosity; Why do you want this rather than

def do_something(var_a, var_b, var_c)  # ==> http://me.com/ 
do_something/a/b/c/
     #stuff
end

??
... the only common string I can think of with /'s in, is a date..

one of the most important objects in nitro for me is the 'request', have 
a look at it via request.inspect and at some point you will find

request.headers["QUERY_STRING"]
#-> "some;thing;nice;"

maybe you could use that... for myself i extract the variables and put 
them into a get-array, it works great for further working with the 
variables from the query.

hope that helps

Hello Brian,

sorry for the late reply, I was camping on a mountain w/o
net/telephone access :-)

MySQL is well supported in Og. Mysql just needs a maximum length on blob keys.
To make the example work just change the following line:

  property :name, String, :unique => true

to 

  property :name, String, :uniq => true

:uniq (unlike :unique) does not  force a unique constrain (ie key) on
the generated table.

Thanks for pointing this out though, I 'll improve the examle and mysql code.

Hello Robbert,

thanks for the suggestions, I 'll have a look at helma. However, I
prefer not to have any ini files.
And I REALLY think that letting Og handle the ddl, is quite possible,
using this all the time :)
Give it a try and you will see :)

Dunno why you would do that, but try something like this:

def my_action(foo, bar)
  ..
end
action :my_action, :route => /my_action\/(.*)\/(.*)/, 'foo' =>
'foodefault', 'bar' => 'bardefault'

you use a regular expression in the route. The above is an example, it
does not much exactly what you want, but I am sure you can work this
out yourself with a nice regexp reference.

regards,
George.

Yeap, as I said, this feature will be available shortly. I am waiting
for debora (ysabel) to send me some rather interesting Og patches
before I go on...

As I privately told Tom, in the next version, this:

property :name, String, :uniq => true

will be just a helper for:

attr_accessor :name
ann :name, :class => String, :uniq => true

so you will be able to do:


class User
  attr_accessor :name
end

and somewhere else:

class User
  ann :name, :class => String, :uniq =>  true
end


regards,
George.

Is there a particular reason that "<!-- these style comments -->" are 
stripped out by the template engine in the .xhtml files?  It's not a 
problem per se, just I was using the comments in different template 
files to keep track of which ones were rendering when, and I noticed 
that they weren't being sent at all.

They are removed to 'compress' output. Perhaps this 'feature' should be removed?

I'm not thinking it's a big problem either way.  I can live without 
them, I was
just experimenting with some funky page layouts with multiple templated
sections and was just wanting to make sure things were being loaded in the
desired order.  Perhaps down the road there could be a "crunch" option to
remove comments and extraneous whitespace to save on bandwidth.  (This 
would be
a cool caching feature:  I was doing some (unrelated) XML work for a client of
ours recently and given the bandwidth limitations for data transfer, removing
the indenting whitespace halved the size of the transmission.  But since I'm
still a Nitro nuby mode I'm not going to worry about it right now :)

Take a peek at

TODO has a list of the things I know are missing at the moment, but 
there's enough there to stumble along in both MySQL and KirbyBase and I 
can likely have Postgres and a shot at Oracle pretty quickly.  (Need to 
implement sequences to support Oracle.)

Oh, and for the record, the mysql-specific store implementation is 61 
lines of code, all very simple and straightforward.  Postgres will be 
about the same, I believe, possibly a line or two more to make sure that 
it uses "SERIAL" instead of "AUTO_INCREMENT".  Here's the three crucial 
method implementations from the mysql-specific code:

 def do_query(sql)
   @connection.query_with_result = true
   @connection.query sql
 end

 def do_exec(sql)
   @connection.query_with_result = false

Yeap, darcs is great, I am a switcher too :) And it makes the handling
of patches trivial.

Deb,

I am sure everyone will aggree that this looks EXTREMELY promising.

Some minor remarks:

Please try to follow the Og coding conventions, ie: 

- leave a blank line after the comments before each method.
- try to make all lines <= 64 chars (but don't go out of the way to
acomplish this, some
  longer lines are ok)

I don't like the name device, isn't device just a store?
I would also like to see some none-sql store abstraction.

I 'll work a bit with your code today, and possibly send you some patches.

MANY thanks,
-g.

I was trying to, mostly.  I figure I can tweak a bit before it becomes
official, but I did change my usual editor settings.  (I'd missed the thing
about blank lines after comments, though even if I'd caught it I'd still
probably add that in later as it annoys me.  *grin*)

I can definitely shorten a few lines here and there, I haven't been putting
that much focus on making sure I kept it shorter than 80 chars.

> I don't like the name device, isn't device just a store?

Initially I was headed towards Device representing purely low-level stuff
and Store being the go-between between a Device and the upper layers of Og.
 Stores represent the idea of CRUD etc on objects and present a clean
interface, and Devices do the low-level translation of objects into and out
of device-specific bits for Stores.

It didn't work out to be quite so seperate, but I haven't yet gone back and
changed the names to Store again.  I still have this sense that a Store and
a Device cooperate but given that I can't pin down the distinction, they
should just be Stores at this point.  I just haven't gotten to it.

One goal I had is that an object could be persisted in multiple stores
without any bad interactions, thus the pulling all the low-level metadata
out of the class itself and putting it into a device/store-specific
repository indexed by class.  However, type selectors and auto-added primary
keys still have to get added to the class itself for the interface to be at
all sane.  This is fine if anything that adds either a type selector or a PK
follows the same standards (i.e. uses either Structured* or possibly a PK*
thing that might end up a superclass again) but it also means that if you
store such an object into a Store/Device that doesn't need them, you'll end
up storing them anyway.  Not sure how to fix that (or even whether it's
really all that important).

BTW, I really need a better name than "autogenerated_key" for something that
uses AUTO_INCREMENT/SERIAL/SEQUENCE, because I kept having to remind myself
that "autogenerated_key" _doesn't_ mean the oid property we just added, it
means the values stored in the key.  And if I kept having to remind myself
while I was writing the stuff that implemented it, it'll confuse people, so
I'm open to any clear suggestions for terms for the two concepts that keep
'em obviously seperate.  (Confused further, of course, by the fact that the
oid key that we add is set to use AUTO_INCREMENT et al by default.  *grin*)

> I would also like to see some none-sql store abstraction.

The KirbyBase implementation is off of StructuredDevice/StructuredTable
rather than the Sql* classes.  Structured* is for anything that has a
table/field-like structure, and in fact I was thinking about tossing in an
XML-based flatfile representation off of Structured*, since that'd be pretty
trivial at this point.  (The KirbyBase implementation, which was quite a bit
more work than the MySQL implementation (which took me about 15 minutes),
still only took me ~2 hours.  Though it could use some work in a few places,
but even so...)  I figure that between an XML flatfile, Kirby and the SQL
stuff, I'll have a good feel for where I have things pushed too far down in
the inheritance tree.

I'm open to ideas about a representation that wouldn't qualify as
Structured*, because I'm sure there are things there that could get split
out and end up in some class between Device and StructuredDevice, but I
couldn't think of anything offhand.

See also my comments in the WISHLIST (I think?) about wanting an abstract
expression of find/update/etc conditions.  Kirbybase's approach of using
Ruby is cool but I'm not sure I want to try to build a general ruby->SQL
clause converter.  I'm willing to build a quick abstraction of the basic
things you'd see in normal condition clauses, since that's pretty simple,
but I'm also open to more ideas there, as it's something I looked at and
went, "Oooh, big, affects people a lot, I'll stay over here for right now,
thanks."  *grin*

(Admittedly, all of this code is colored by my work on Hibernate/JBoss/EJB3;
please do point out places where I'm suffering from blind spots if you see
'em.  That's an open invite to anyone on the list, too, btw, not just George.)

Good point! It would be best to hear other people's opinion before
working on integrating this with Og.

I do feel that the code has a java feel (bloated) in some places, but
I am sure we can fix that :)

Thanks,
George.

Another small question:

What does the name Structured denote, ie, what is an 'Unstructured' store?

Deborah, all...

I was playing a bit with the directory structure in the patch, and I
would like to suggest
some changes, to make this more compatible with the rest of Nitro/Og
code. I also suggest changing the notion of 'table' into 'schema' to
be more compatible with non-sql stores. find_options was changes to
finder to be shorter (any ideas for a better name?).

I would love to hear your comments.

Hee!  Yeah, it's been a few years since I was doing active work in Lisp or
Scheme (or Smalltalk or Eiffel).  Though I do seem to keep coming back to
persistence mechanisms; I wrote a transparent OODB interface for Eiffel in,
mmm, '91?  And distributed database systems and JBoss and I can't count the
number of times I've had to build persistence in systems for one job or
another, usually for political rather than technical reasons, gah.

I'm a C++ and python expert and have been stuck professionally in Java and
C# the last few years to boot, so it's taking a bit to get back into the
functional flow, especially with Ruby's OO-tinted view of functional.  I
suspect that even the bits where I'm getting away from C++/Java/C# idiom I'm
still being pythonesque.

Really, python's the only non statically typed strongly typed language I've
ever built anything particularly significant in; I like static/strong typing
if the underlying support is there for it (and it isn't there in Java,
dammit, though 1.5 is at least a HUGE step forward...similarly for C# 2.0,
enough so to make it worth using the Microsoft beta stuffs right now).  But
then both the full C++ STL and XPath/XSLT actually make sense to my brain,
so I'm an established nutcase right there.  *grin*

Anyway, I could bitch about languages all day.  I'm enjoying the hell out of
Ruby and more than a little glad to find something that uses it that also
does what I need in a way that works well, namely, Nitro.  Rails has some
very cool ideas but I quickly ran into major limitations w.r.t. any kind of
complex modular organization, and given that Ruby's _really_ strong when it
comes to modules, that annoyed me to no end and turned me off for a while.
Then I found Nitro and had a few good yay moments.  :)

Amusingly, I still haven't written a single line of code specifically for
the thing I wanted to use Rails for in the first place.  Or, rather, I have
a bunch of notes and several possible DB schemas, but I keep ending up
building infrastructure bits to do what I need instead of working on the
application.  That, and having ljArchive work I should do, and another
application I'm working on, and JBoss-EJB3 work I should do...oh, yeah, and
my job, and my family, and the occasional video game...

What were we talking about again?  *grin*

A pure unstructured store would be one that serialized the objects as blobs,
I would think.  Nominally, a Structured store is one that needs a lot of
information about the inherent structure of the objects stored in it
(objects/properties/relationships-between-instances) in order to correctly
and efficiently store and retrieve the objects.  You could even build an
unstructured store on top of a SQL database by just serializing the object
and storing it in one field (though I wouldn't think you'd usually want to
do that).

I was considering the idea, btw, that a caching layer could be implemented
as an unstructured store on top of another store; as in-memory objects,
there's no need to know much about the internals, just enough to keep
references resolved correctly and make sure that multiple requests for the
same object kick back the same instance.  (I actually have an implementation
of something much like that in python, on top of pickle/unpickle into a BDB
database.)

It's likely that the most basic bits of primary keys and relationships
between objects needs to get kicked up a level in the inheritance tree -- my
first pass through had that separation, but I decided I didn't understand
where the line really needed to be drawn yet, so I switched back to having
them all together until I sorted out where the line really was.

It's also likely that "Structured" is (mmm, gut-feel says) about three
different concepts mashed together; I'm hoping that trying to implement a
few different underlying layers will tease out where the lines between them
belong.  The only line that was very clear to me was the line between
"object structure" and SQL, thus the Structured/SQL split, which is pretty
carefully defined and kept clean (I think).

Does that at least make general sense?  It's 1:30 am here and so I'm a
little spacey.  I should go to bed soon.  *grin*

I like both the structure and the naming changes.  "finder" works for me
entirely because it implies that we're going to expand on that annoying
abstract find conditions thing.  And that does seem like the right place for
it, long term, anyway.

If you get around to patches to shuffle things around, feel free to send
'em, I'll poke and incorporate.  (Make sure 'rake' still passes all tests!)
 If not, I'll probably shuffle/tweak names tomorrow.

I've not done anything to set up darcs auto-receive by email yet, but I may
do that too at some point here.

As I am still on vacations and not fully familiar with your code I
would really prefer that you made the changes (my gf will kill me if I
am coding all the day ;-)).

Another thing that 'bothers' me is the cloning of the property
metadata into structured_fields. Can we avoid that?

best regards,
George.

PS: I am attaching an updated version of the proposed dir structure,
with some comments to help you.

Funny, this is how the original (3 year old) version of Og worked. Let
me tell you this was a bit problematic (like the instiki guys recently
found out). But it IS useful for some applications.

Interesting idea.

Yeah, it makes sense :)

PLEASE.  *grin*

The biggest thing in my wishlist right now is that property metadata alone
isn't reliable for building tables and the like.  I wrote a set of "unit
tests" to explain what behaviour I really need (and am having to emulate by
walking the properties metadata multiple times to sort out what the user
really intended).  They're in WISHLIST.

I think, given your comment onlist earlier about annotating attributes
that're just created with attr_accessor and its ilk, that this should be
pretty easy to get to.

The big thing that causes pain at the moment is that properties copy
themselves down onto subclasses, which means that if you then dynamically
add a property to a class, its information doesn't get propagated correctly.
 The other biggie is that you can't tell where something was declared, so
you can't sort out where it belongs without comparing properties on a class
to its parent's properties...which may or may not have everything because
something might've been added along the way!

If we can get properties to be reliable and complete, we can drop nearly all
of the need to walk/collect property metadata, and fields can really just be
specific to dealing with persisting the properties.

On the bright side, if you look at what this collection of code needs out of
properties (and can't get right now, and thus has to do "on top of" them), I
suspect you'll have a pretty complete set of use cases for property
metadata...  I _think_ the "tests" listed in my WISHLIST file actually cover
pretty much everything I needed in a very concise way, and it's not that
much.  Though I didn't specifically write a test to express the idea that
adding a property dynamically doesn't violate any of the tests, and you'd
want something like that for a real set of tests.

(That, and the "meta"/"metadata" thing, which drove me up the wall until I
got it sorted out far enough that I stopped trying to access <class>.meta
all the time.)

Was just at NitroHQ.com ... 

The "documentation" section shows the apis as of 0.19 ... which as
I've been tracking the mailing list ... has been changed significantly
...

uh, when somebody gets the chance, it would be good to bring that up
to date ...

I know I have the local docs for things, but it's still nice when you
are trying to show stuff to people to talk them into
downloading/installing it...

Anyways, just my $0.02USD.

Sorry, that wasn't completely accurate ... I was specifically
referring to the API Reference documentation not the document page (
where the sample projects are )... even though those are out of date
too...

This works more or less like Rails, ie the controller renders the
template 'my_action.xhtml' when rendering the action 'my_action'.

This was discussed in more detail earlier in the list. I think the
examples illustrate this quite well, if you still have problems,
please explain a little better what you do not understand.

regards,
George.

There's KirbyBase and a filesystem implementation, at least, though I don't 
know for sure the current state of either.  The stuff I was spamming the 
list about late last night will likely open up options for more, though.

Is there something in particular you're looking for?

Just a light weight storage for my Ruby objects.  I don't need the power (or 
hassle) of a relational database.

I guess this can be implemented too..

This the way to go, the property system  must be improved. Duplicating
property metadata in fields is not elegant/robust.

It's not easy to have both:

<class>.meta

and

class <class>
  ...
  meta ...
end

An older version provided support for Oracle but the adapter is not
updated for the latest version. Given the fact that there is a patch
for the store subsystem in progress this will have to wait for the
moment.

Subject: [Nitro] Question about Options
Message-ID: <379ea2750508201736882d01f@mail.gmail.com>

Hello,

I've been enjoying my time learning Nitro and Og, but going through
some examples brought a question to mind. When you have something
like:

    Og.setup(
      :name => 'test',
      :store => 'sqlite3'
    )

or

    over_twentyone = People.all(  :condition => 'age > 21' )

I notice the ":[option]" syntax. I looked in the rdocs, but couldn't
find a list of available options for things like Og.setup or
[Klass].all

Does such a list exist? (Not limited to just these examples, I mean in
general including things like 'property :hits, Fixnum, :sql_index =>
true', etc.)

Thanks a bunch,
-Mitchell;

Hello Mitchel,

There is no such list at the moment. But I 'll go through the code and
add some documentation in time for the next release.

OK, that works thanks. There are plenty of other bugs in the tutorial: I
started to fix some, but was left with others.

(Note that Mysql doesn't like VARCHAR2, you have to change to VARCHAR)

I'm currently stuck here:

# ** FIXME ** gives "wrong number of arguments (0 for 1) (ArgumentError)"
cat.add_post { |po|
     po.title = 'Title'
     po.body = 'Body'
}

What's the correct syntax to use?

Thanks,

Brian.

FYI, I'm planning to be willing/able to write this as soon as things
stabilize.  You might want to ping me in case I'm not paying close
enough attention.

While you're trying to polish up the Og tutorial: It would be nice if 
someone could write at least one additional sentence to the relation 
definitions. I can guess and only guess that belongs_to is the opposite 
site of has_many, but what is refers_to (and has_one) then?

Thanks! - Bernd

Subject: [Nitro] Modelling controllers strategies
Message-ID: <430A15AD.4080709@cronosys.com>

Hi, in my rare pockets of spare time I've been experimenting with a 
designing
a small CRM application using Nitro.  (See www.SugarCRM.com for what I'm
modelling the UI after, and if you are in a puking mood, download their 
open
source zip and take a peek).  I started by looking at Spark and got just
some very basic stuff running so far.  What I've run into is some confusion
on how the controller class should behave for what I'm trying to do.  Spark
is simple in that it (basically) deals with just one Og object (WikiPage). 
What I'm trying to do deals with (potentially) numerous business logic
objects (Contacts, Accounts, Projects, Leads, etc).  I've got basic Og
objects for these, and that in itself isn't a problem.

For example, I envision talking to the controller like so:

 /view/Home -- Display homepage (index default page)
 /view/Contacts -- View Browse/Search/Panel for Contacts
 /view/Accounts -- View Browse/Search/Panel for Accounts
   (Or perhaps have a "/search/Contacts", use different controller call)
 /view/Contacts/239030294083820 -- View this contact's details
 /edit/Contacts/239030294083820 -- Edit this contact's details

All "screens" will have some common header and footer templating logic,
but the main guts of the page will behave based on which object type
you are loading/editing.  So my initial question is "should I try to
have one controller try to handle everything?"  Like so:

-----8<-----
class MyController < Nitro::Controller
  def view(screen = 'Home', oid = '')
    @someobj = MyBaseClass.find_by_oid(oid)
    ### now try to determine what to do based on the screen
    if screen == 'Contacts'      # do something...
    elsif screen == 'Accounts'   # do something...
  end
  ### and so on...
end
-----8<-----

Or would I be better off having a controller per object type (even though
I'm not quite sure how to handle the common header/footer stuff)?

-----8<-----
class ContactsController < Nitro::Controller
  def view(oid = '')
    # We know it's a contact already
    @somecontact = Contact.find_by_oid(oid)
  end
  ### and so on...
end

### probably in a separate file:
class AccountsController < Nitro::Controller
  def view(oid = '')
    # We know it's an account already
    @someaccount = Account.find_by_oid(oid)
  end
  ### and so on...
end
-----8<-----

Years of mod_php style programming is making my grokking of the MVC
paradigm a little bit challenging.  :)  Any suggestions to the above, or 
maybe
there's a better way that I'm missing?

Just pushed changes based on the structure you sent, plus a few tweaks to
make a few things a little more consistent (or more accurately, less
haphazard, really...)  You should peek at my module/class naming,
particularly for Store and Schema/Schemas, and tell me if it bugs you.  :)

Sorry I didn't get those sooner, it was a very hectic weekend.

On first sight, this looks great :) Can you make this code (at least
the mysql adapter) plug into the rest of the Og infrastructure? Then I
can work on the sqlite/psql adapters. If we can also get the kirby
adapter running this would be great!

I 'll better investigate this later today. 

Many thanks,
George.

I would suggest to go with separate controllers for 'important'
objects. You can reuse the same layout by defining a common Page
element like it is done in spark. Check out the file src/skin.rb.

A better example of nitro will be released real soon now.

George.

Subject: [Nitro] Nested Intervals
Message-ID: <afd80b5405082300127d678d16@mail.gmail.com>

There is a small project for anyone who wants to help with nitro development.

Have a look at lib/og/mixin/tree.rb

This is some experimental code for a nested intervals mixins a more
sophisticated version of the nested sets algorithm used in the
hierarchical mixin for sql tree traversal. If anyone could go on   and
finish this code it would be very helpful. There is a link in the code
that points to an article that describes this algorithm.

George.

Subject: [Nitro] Redirect change.
Message-ID: <afd80b5405082302361631dae@mail.gmail.com>

Hello all, 

I am sightly changing the behaviour of redirect. I think the following
excerpt from the test case demonstrates the new behaviour:

	def test_redirect
		# relative url, the controller base_url is prepended
		redirect 'hello'
		assert_equal 'http://www.nitrohq.com/base/hello',
@controller.context.response_headers['location']
		
		# absolute url, use as is.
		redirect '/main'
		assert_equal 'http://www.nitrohq.com/main',
@controller.context.response_headers['location']
	end

This will make possible to rewrite more reusable controllers that can
be mounted on different paths. If anyone sees a problem with this let
me know. This will probably break some existing code, but it is 
really easy to fix.

regards,
George.

I'll work on that.  The Kirby adapter should work already for basic stuff, 
but it needs more functional tests.  All I have in there right now is 
create some objects, make sure they exist in the KirbyBase, and then do a 
basic find and make sure we get back what we expect.

I'll probably also do a quick sketch of both the sqlite and the psql 
adapters but I won't do much more than that; it'll give you an easy 
starting point, they'll definitely both need functional tests to make sure 
everything's covered.  Ideally anything that's used by more than one 
adapter will be up in a higher level somewhere, possibly configured by one 
of the db_features flags, so the DB-specific adapters can be really simple.

For the record, the functional tests require appropriate configuration and 
permissions (e.g. the MySQL tests require a mysql user with permissions in 
a test database) and so they won't be included by default in "rake test", 
unlike the unit tests.  I'll make sure there's some docs on the subject.

Thanks. Here are some more things which don't work from the tutorial:

(1)

    # FIXME
    cat = Category['Programming']

This gives the following exception:

ERROR: DB error Unknown column 'Programming' in 'where clause', [SELECT * FROM ogcategory WHERE oid=Programming]

whereas the tutorial says: "As a convenience, Og allows you to lookup the
category using the special property 'name'"

(2)
    po = Post[1]
    p p.title

    # FIXME
    p po.categories[0].title

gives exception "undefined method `categories' for #<Post:...>"

(3)
    com = Comment.new('Hi there')
    p.add_comment(com)

another 'method missing' exception

(4)

    po = Post[1]
    # FIXME
    po.update_properties "body='Hello world'"

Gives the following exception:

/v/build/nitro/og-0.22.0/lib/og/store/sql.rb:334:in `send': undefined method `body='Hello world'' for #<Post:0x82beef4> (NoMethodError)

        from /v/build/nitro/og-0.22.0/lib/og/entity.rb:30:in `update_properties'
        from run.rb:132

(5) The callback function isn't called:

class Post
  ...

  def og_post_insert(conn)
        puts 'Hey, a new post was just posted!'
  end
end

I found a few other errors in the tutorial which I was able to fix - these
are reflected in the attached patch.

Apart from this, it worked just fine :-(

Brian.

Subject: [Nitro] Foreign key constraints
Message-ID: <20050823204455.GA1453@uk.tiscali.com>

Question 1: would it be possible for Og to insert foreign key constraints
automatically? I'm thinking particularly of the 'belongs_to' and
'many_to_many' relationships.

For example:

    class Tree; end

    class Tree
        property :name, String
        belongs_to :parent, Tree
    end

IMO this ought to do an:

    ALTER TABLE ogtree ADD FOREIGN KEY oid_parent_oid
                       (oid) REFERENCES tree (parent_oid);

If this sort of stuff has to be done by hand on the SQL databases after the
fact, then it doesn't really seem worth having Og create the tables
automatically from the metadata; it might make more sense to create the SQL
tables manually, and generate the class definitions from that. (Although
some people might prefer to ignore database integrity checks for convenience
of programming, I don't think that's a good way to write a robust
application)

Aside: there's a slight bootstrapping problem with this particular example,
since

    root = Tree.new 
    root.parent = root 
    root.save

inserts an entry with oid=1 but parent=NULL. I would like to have a not-null
constraint on parent too; "belongs_to" becomes "must_belong_to" :-) But in
the case of a tree, I don't mind having to manually send some SQL to insert
the root node:

    insert into ogtree (oid,parent) VALUES (1,1);

Question 2: Are transactions implemented at all? Can someone give me some
example code showing how they would be used?

I note they are not implemented for mysql:

  def commit
    # nop, not supported?
    # FIXME: InnoDB supports transactions.
  end

However it *is* possible to create the correct table types:

  db = Og.setup(
      :store    => 'mysql',
      :name     => 'test',
      :user     => 'root',
      :password => '',
      :table_type => 'innoDB'
  )

Having both referential integrity and transactions is I think important for
more complex applications, when inserting multiple related objects.

Regards,

Brian.

Thanks for the encouragement.  As of this moment we have 6 people
in the #nitro channel on freenode, and I have already met some
nice people and had one progress-stopper solved.  Hint: "require"
your model file(s) before you "require" your controller file(s)
or it may seem like Og is not weaving in its magic methods.
As you see I am still learning the ins and outs of Ruby ;)

data from multiple tables, some fields editable, some
not, heavy validation, database-backed list boxes, and
careful handling of locking and transactions because
multiple people will be trying to look at and edit
data potentially at the same time.

How about introducing authentification to the wiki? There are more 
attempts of vandalization than additions / updates....

Ehm, I guess this is a manual task :)
Btw, the forthcoming release of Nitro includes *advanced* scaffolding
helpers that are helpful even in non standard cases like the one you
describe.

Hello all,

I would like to factor the CgiUtils out of lib/nitro/adapter/cgi.rb
Any idea where should I  move them, how to name the file?

What kind of validation do people prefer?

  - graphical text entry (what's this called again?)
  - IP validation
  - Memberships
  - Other?

It's called CAPTCHA (http://www.captcha.net).

That's probably best because it doesn't require registration.

I think a very simple:

	Please enter the result of #{ rand(10) } + #{ rand(10) }

would do, assuming that everyone can add two numbers ;-)

You'll want to create some DSL methods to simplify your task. If
they're generic enough they may be of use to Nitro in general. For
instance I can imagine some validation "ann"-type methods.

    valid :a, { |a| a =~ /^@/ }

Sorry if this is a stupid question (still haven't begun working with
Nitro directly) George is it possible to add meta info with #ann? That
would be useful. Say like

  ann :a, :editable => true

As for list boxes, I have some xHTML helpers that build just such
lovely things for you. But I'm REAL busy at the moment. I'll make them
available as soon as I can. Please somene remind me if I don't do
anything on this within the next few weeks.

As for locking and transactions. The first and foremost thing to do is
use an advanced database. PostgreSQL is good for this sort of intense
usage. The easiest way to protect records is to compare changes --if
someone change something since you accessed the record the warn the
user, show the difference, and give an option to overwrite. If you
like to inform the use of the potential of conflict prioir to record
save operation then there may be a way to get more info from the DB
(locks) (not sure as the former always seemed good enough to me), but
if you do and want it non-db dependent you'll have to have shared
process that keeps track of them. A very simple service really. Put a
REST interface on it for good measure. Might be a nice addition to
Nitro too.

Maybe so. But if some went out of their way to target the site, that
would quickly be overcome. Of course you could make it a littel
tickery, a random set of simple english word problems. I'm sure I
could come up with a 100 of these in day.

  "What is 4 plus the number of legs a dog has?" :-)

OTOH, IP validation is more interesting, but I'm not sure of
limitations. Essentially your IP is kept on record as valid. If you
submit and it's not there it asks for your email address to which it
will send a validation email, i.e. either reply back or click link,
which then adds your IP to the list. From then on you wont have to do
it again, at least not from that location.

you can do that with 

action :a, ...

But the whole property/metadata system is being reworked/simplified at
the moment. Dunno if this will make it for 0.23.0 though...

version 0.23.0 will include ADVANCED scaffolding functionality. Stay tuned.

IP-validation is of no use... IP's change all the time, and i don't like 
the thought to reregister my IP-address all the time while other people 
wich get my IP have access... i don't think it's THAT dangerous, but it 
is not secure and i'm sure it won't be comfortable - especiall for 
people who need some proxy-server to access the web and whose IP changes 
all the time due to load-balancing between proxies...

and i have one question ... is this all about preventing vandalizing by 
bots AND humans?

for bots the job is done by some simple image, but what hinders humans 
to access and vandalize?

Good point.

Use images to block bots.  Use an editing delay to slow down humans.

E.g. When editing a given page, store the IP address for x seconds (60? 
10?), and block further editing of other pages until an editing hold for 
that IP address has expired.  Then delete the stored IP address.

Maybe use a cookie that expires after, say 60 seconds?

Annoying to legitimate users, though I suspect most people are not 
trying to edit multiple pages one right after the other.

What would be cool is to have a "revision request queue" for anyone who 
isn't authenticated (by whatever simple mechanism).  I'd guess most wiki 
vandalizers wouldn't bother if they needed a basic user account to 
accept/reject revision requests.  That way anyone could still 
contribute, but the work of non-auth'ed vandals wouldn't affect the site.

I've run the script to make the exe, but now I need a clean box to test 
it on :)

I need to be sure that it works on a system with no Ruby.  And, oddly 
enough, all four of my computers have Ruby installed.  (Well, actually, 
I have a fifth computer, a C64 but it's in a box in the closet, so that 
doesn't count.)

Looks like a job for VMware.  Or maybe WINE?

i'm sure we can find a 'clean' windows box in our office - you could 
forward me the .exe to check it out!

why not try a combination, i.e.:
1. frequent users can register,
2. someone wishing to contribute should at least answer to a CAPTCHA or 
other kind or question
3. inform everyone that their contribution is logged (their ip, any 
other info we can get from their client's request)

later we could add a moderation step if wewish, but i think it 
complicates things too much....

i agree with you, that's a good 3-level-system
level 0 guests, who can add entries, but have to answer that anti-bot 
thing - these entries are not going to be added immediantly someone with 
a higher level has to accept the modification.
level 1 - the normal registered user, he is allowed to post while logged 
in under his name. They are also allowed to accept entries from level 0 
- wich are afterwards under their resposibility and get their name 
mentioned...
level 2 - moderator, can multi-delete entries by some criterias as 
timespan/author/IP..., administrate users, ban user-ids/ips... whatever

i would love to have such a system :)

Message-ID: <1125011002.6863.6.camel@localhost.localdomain>

Hi ..

Following the recent thread in c.l.r, I did a quick modification of the
Glue Logger class to get around the issue (I need my own Logger).  Here
is the diff (0.22.0 release):

-----------------------< glue/logger.rb >-----
10c10
< class Logger
---
> class GlueLogger < Logger
80c80
<   @@global_logger = Logger.new(STDERR)
---
>   @@global_logger = GlueLogger.new(STDERR)
86,87c86,87
<       @@global_logger = Logger.new(logger)
<     elsif logger.is_a?(Logger)
---
>       @@global_logger = GlueLogger.new(logger)
>     elsif logger.is_a?(GlueLogger)
150c150
<   remove_const "Format"
---
>   # remove_const "Format"
-----------------------< glue/logger.rb >-----

This also means that there are also changes in the Og code.
Specifically, a global replace of 'GlueLogger' for 'Logger' in the
following files:

 og/manager.rb
 og/store.rb
 og/store/filesys.rb
 og/store/memory.rb      
 og/store/psql.rb        
 og/store/sqlite.rb
 og/store/kirby.rb       
 og/store/mysql.rb       
 og/store/sql.rb        
 og/store/sqlserver.rb

Given that these are trivial edits, I haven't given the diffs but I can
on request.

Thanks for the great tool!

Regards,

It overrides the Logger class and changes the default format, and
trace() methods.  In addition, it turns Logger into a singleton, which
kinds of hoses having your own logger(s) present.

So, making it a GlueLogger < Logger gets around this.  All of the Og and
Glue classes can be happy with this new behaviour, and we can still have
normal loggers elsewhere.

The debate in c.l.r is about overriding standard class methods and
behaviour.  Extending is okay, IMO, modifying is another issue.

In George's defence, I think that he took the code from someone else.
Given the gift he has given us with Nitro and Og, this is a small price
to pay ;-)

On something of a side note, did anyone else find that thread weird?  I 
can understand wanting to point out design or code flaws, and having a 
public discussion on differing opinions, but it seems perversely nasty 
to take free code, and, because it gave you a problem that the author 
almost certainly did not intend, publicly identify the code author and 
essentially rip him a new asshole.

There are any number of ways to address such issues with a bit of tact, 
while still having a public discussion that doesn't point to a 
particular offender.

This is true.  I can understand the OP's upset at having to debug
someone else's code.  And we do the best we can.

Read it like he can't really speak English in that post.  I am sure that
he doesn't mean to harm ..

Yeap, that was offending. I did post an answer to c.l.r
(http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/3e0d03d839a45c6b)

Due to the newsgroup-list bridge problems, this got somewhat lost.
Perhaps it is better that way, flame wars are not really needed. But
then again, posts like this
(http://www.livejournal.com/users/djberg96/40192.html) are not needed
either...

oh well...
George .

Message-ID: <4b6f054f05082604065fbeccae@mail.gmail.com>

Hi,

Since Rails has defined cattr_xxx methods as accessors to class
variables, that name is not available to the more useful accessors for
class instance variables. Not wanting to conflict with Rails' Active
Support lib on the issue I'm leaning toward the use of iattr_xxx. Does
that sit reasonably well with others?

Note: I hanker not to include the mattr_xxx aliases for cattr_xxx.
Please don't use those. How often, if ever, have you heard class
varaibles (i.e. @@v) refered to as module variables? The whole alias
business somtimes just gets a little overboard IMHO.

Thoghts?

The problem is that I DONT like to have GlueLogger all over the place...
I prefer the solution posted in the ruby-talk mailing list.

After a quick look I do not understand why this is better though. (And
in fact I don't understand Zed's problem too).

will have a look over this over the week end.

Hi all:

Problem:

I have the following 'pipeline'

Compiler.setup_template_transform do |template|
   template = Elements.transform(template)
   template = Template.transform(template)
end

if I use the render method "render_template" from a
controller action, this pipeline will not get executed...
leaving all my lovely <this> and <that> elements un-renderd

Solution:

To allow actions to correctly render templates other than their own
using the pipeline, would it be a good idea to move the "pipeline"
setup onto the Template object within glue? this should allow the  
templating
engine to be more versitile on its own, and make the render_template
work as I would expect it to?

ie. Template.setup_template_transform {|t| #some stuff }


Please tell me if there is a good reason for not doing this that I have
neglected to see Or if this can be achieved some other way?


ps: more love to the #nitro :-)

chrisfarms.

Ended up talking about this on the IRC channel, trying to help manveru with 
something.  He consented to having the log of that bit of our conversation 
put up on the wiki, and I thought it might be helpful to other folks. 
(Yes, I used nitro-auth as an example, since I had it handy.)

Given the current upcoming release of nitro 0.23, I'm not going to create a

I'll see if I can do it justice.  Og is one part of my application,
let's say a data collector is another.  The connection info comes from
the database via Og, into the collector, which fires off a threaded
collection.  The data comes back, is parsed, trimmed, reduced, and
stored in the database.

So, there is a logger for Og, a different one for the collector and a
third for the parser and analyzer.  Why?  Cause different people are
interested in different things, with the Loggers being logically at
different levels.  For example, if I have a communications problem
collecting data, why have a whole bunch of database info gumming up the
logs?  Easier to have different logs than to have one and have to filter
it all the time.

The current design of the Glue logger 

 a. makes it a singleton, so there is only one log possible
 b. changes the format, and I need the timestamp info for the comms
threads
 
Unless I am mistaken, which I could well be.  A GlueLogger "fixes" both
of these issues at minimum cost and no impact to third party libraries.

Just my $0.02.  

Regards,

-mark.

I would think that using log4r instead of tweaking Logger might well also 
solve it?

Ok,

I have Nitro & SQLite3 both setup as rubygems on my system.

I'm trying to run the following through irb.

--SCRIPT--
require 'rubygems'
require 'sqlite3'
require 'og'

db = Og.setup( :store => :sqlite, :database => 'blah.db' )

class User
  property :name, String
  property :pass, String
  property :age, Fixnum
  has_many :comments, Comment
end

class Comment
  property :title, String
  property :body, String
  belongs_to :owner, User
end

a = User.new
a.name = "joe blow"
a.pass = "shhh"
a.age = 13

b = Comment.new
b.title = "Comment #1"
b.body = "testing 1 2 3"

a.comments << b
--SCRIPT--

And at the comments << b line it blows up saying that there is no
comments method for User.

What am I doing wrong?

For sure.  That is, of course, George's call.  Given that there is
already a requirement for a number of external libraries (RedCloth and
Facets), adding Log4r isn't a big issue, IMO.

Certainly, log4r solves the formatting issue.  The singelton issue is a
design level issue.

Thanks.  I've set up a VMware instance with a bare-bones Win2K, and I'm 
happy to report some basic success.

The app does, well, next to nothing, but the distributable exe does kick 
off WEBrick and allow one to load the default Nitro index.html page.

Next: See if it actually loads and runs Nitro controllers and custom libs.

Actually, in taking a second look, I found that my simple app already 
included a basic controller and some elementary URL mapping, and running 
  it from the rubyscript2exe output successfully responded with some 
simple JSON.

So I'm happy.

Subject: [Nitro] class instance attributes method names?
Message-ID: <4b6f054f050827200130e234ed@mail.gmail.com>

I have attr_x like methods for creating class instance attributes.
Unfortuanetly Rails has set the precedence for using 'cattr' to mean
accessors for class variable attributes, ie. @@v (despite their
general uselessness), otherwise I would of course have used that name.
So now I'm stuck with deciding another. Currently I'm using: 'iattr'.
'i' for instance. But that's a pretty bad misnomer if you think about
it. Yet I don't much care for the obvious choice of 'ciattr'.

Any opinions/alternatives?

Hello,

either define tour classes *before* Og.setup or call og.manage_classes
after you define them.

Maybe we can add support for log4r too.

The current logger is NOT a singleton, you just *can* use it as a
signleton, but you can also instantiate loggers if you want. Only the
formatting changes. So if we add a way to setup the format, everything
works ok. (Ie we can setup the version used by Nitro differntly than
the default).

George,

I did things the way you asked and got a bit farther ...

Here's my script now...

--SCRIPT--
require 'rubygems'
require 'sqlite3'
require 'og'

class User
    property :name, String
    property :pass, String
    property :age, Fixnum
    has_many :comments, Comment

    def initialize( name, pass, age )
        @name = name
        @pass = pass
        @age = age
    end
end

class Comment
    property :title, String
    property :body, String
    belongs_to User

    def initialize( title, body )
        @title = title
        @body = body
    end
end

db = Og.setup( :store => :sqlite, :name => 'blah' )

a = User.new( "joe", "shhh", 13 )
b = Comment.new( "comment #1", "testing 1 2 3" )
a.comments << b

a.save
b.save

c = User[ 1 ]
puts c.name
puts c.pass
puts c.age
puts "Comments Length : #{ c.comments.length }"
c.comments.each { |curr| puts "#{ curr.title } -- #{ curr.body }" }
--SCRIPT--

And here's the error I get:

I guess I'm not as happy with all of the updates as some others might be 
... I think I was playing with version 0.20 or 0.21 ... and all of this 
stuff used to work .. and I didn't used to need to call #save it just 
did it.  It's not that I mind, it's just, well, seems things used to be 
simpler... I guess that's what happens when projects add features ...

Anyways, if you can help, I do appreciate it.

I played a bit more with my script ... and it seems that the magical 
goodness of Og redefining tables doesn't work for sqlite ... so, when I 
blew away the sample database, it recreated things and it seems to work now.

I think you should add some kind of an easy to read error message that 
the class definitions don't match up with the database model, and that 
the database model is not alterable ( as easily ) in sqlite

Anyways, thanks for your help.

Oh, also, I was trying to follow the example where you use User[ 'value 
from name field' ] and it doesn't seem to like that ... yet another 
incompatibility with sqlite?

Thanks again.

Figured I should post code...

--SCRIPT--
require 'rubygems'
require 'og'

db = Og.setup( :store => :sqlite, :name => 'blah' )

class User
    property :name, String
    property :pass, String
    property :age, Fixnum
    has_many :comments, Comment

    def initialize( name, pass, age )
        @name = name
        @pass = pass
        @age = age
    end
end

class Comment
    property :title, String
    property :body, String
    belongs_to User

    def initialize( title, body )
        @title = title
        @body = body
    end
end

db.manage_classes( User, Comment )

a = User.create( "joe", "shhh", 13 )
b = Comment.create( "comment #2", "testing 4 5 6" )

a.comments << b

puts a.name
puts a.pass
puts a.age
puts "Comments Length : #{ a.comments.length }"
a.comments.each { |curr| puts "#{ curr.title } -- #{ curr.body }" }


c = User['joe']
puts c.name
puts c.pass
puts c.age
puts "Comments Length : #{ c.comments.length }"
c.comments.each { |curr| puts "#{ curr.title } -- #{ curr.body }" }
--SCRIPT--

The blow up is at the c = User['joe'] line...

the error is:

Subject: [Nitro] ajax autocomplete example
Message-ID: <op.sv743tfdg3glhz@jo>

Hi

I played around with the ajax example a bit and stumbled over the  
auto_complete function, which is not yet fully useful like this (imho). I  
thought, wouldn't it be better, if there was some kind of "search"  
mechanism built in, so you can type a few chars into the box, and then  
just get the corresponding items from the list.
Well, I came to a solution, which is pretty much simple, but it's also  
crap. I wonder if there is a better way to do this.

--- public/js/controls.js
this.options.method        = 'get'; (instead of post)

--- src/controller.rb
def country_auto_complete
   searchstring = get_ajax_value

   countries = %w{Greece England USA Germany Italy France Netherlands}
   countries.delete_if {|x| x !~ /#{searchstring}/i }

   build do
     ul {
       countries.each { |country| li country }
     }
   end
end
	
def get_ajax_value
   request = response.headers["REQUEST_URI"]
   /(.*)_auto_complete[^\?]*\?\1=([^&]*)/.match(request)[2]
end

--- public/index.xhtml
<p>
       Auto complete example:<br />
       <label>Enter a country:</label>
       <input autocomplete="off" type="text" id="country" name="country" />
       <div id="country_auto_complete" class="auto_complete"> </div>
</p>

autocomplete="off", since Opera (8.02) doesn't seem to respect the  
el.autocomplete = "off" from javascript, and the additional name="country"  
to distinguish the GET value from other values and get it by that Regex.


Well, while this approach certainly works quite well, as you can see,  
parsing the REQUEST_URI is pretty much ewwww. (I wouldn't even know how to  
do that stuff with POST...)
What I would like to know, is there a more standard way to do this?

If there isn't, here would be my idea for an api:

def country_auto_complete(ajax_return_values)
   ...
end

Sadly I'm not good enough to code that myself, would love to hear your  
ideas.

I sent an updated email with new problems over the weekend, I've not
seen any traffic on it ... does anybody have a moment to tell me
what's up?

I'm not near my home computer at the moment where I sent the original
or I'd be reposting it ...

Really, I'd love a response... Thanks in advance for any time you can
spare to help me get things working properly with Og.

Subject: [Nitro] Og and Hash
Message-ID: <Pine.LNX.4.62.0508300422520.12933@theseas.softlab.ece.ntua.gr>

Hi, I have a question for the list:

I want to make a relation between 2 classes, eg Unit and Tenant. Normally 
it
would be something like this:
class Unit
has_many :tenants, Tenant
end

class Tenant
belongs_to :unit, Unit
end

but I want to associate the 2 classes using a Date. Each tenant is related
to a Unit with a specific Date. How can this be done? I thougt of Hashes 
but
I am not sure how to combine the has_many, belongs_to directives with the
Hash:

class Unit
has_many :tenants, Tenants
property :leases, Hash(Date, :tenants)
end

The above code is of course wrong but it kind of explains what I want to 
do...

Thanx

One more question:
if I have a "property :name, String" with value, lets say @name = 
'apple' can I use Localization, so that when I do in the .xhtml file
something like <p>[@name]</p> it will print the name in different languages?
What should I put in the yml language files in this case? Something like:
conf/locales/en.yml
apple: Apple
conf/locales/jp.yml
apple: Ringo

Thanx in advance :-)

Thanks for the response.... Man we need a fresh tutorial on Og.

And we need to keep it up to date...

I've been programming for years and this is really frustrating... Og is 
at a relatively high version number now ( almost 1 ) the API should be 
more solid than this.

I know you're trying to make things the best they can be, but it's hard 
to  gain traction when the project keeps pulling the rug out from under 
my feet. 

It also makes the project hard to sell to others. ( as far as trying to 
get other developers to use it ).

I was searching today and I found the Nitro::TableMixin !!!!!!! George you 
are amazing! One request: could you include a TableMixin version that has 
both Column Headers and Row Header? eg

        | Col_1 | Col_2 | Col_3
------------------------------
Row_1  | Data  | Data  | Data
Row_2  | Data  | Data  | Data

If it can be easily done with this existing version, could you give an 
example? Thank you :-))

good you are asking that question :)
i asked Ysabel the same question some days before and she said it is 
broken but should be fixed in 0.23 (wich is sometime this week i heard)
i really wanted to use that, but ah... have to wait some days ^^
sorry that i can't provide you a quick fix or something, and i've got no 
clue about the 2 other questions you wrote to the list.
though the list-update-thing could be done easily with a bit of 
javascript... but i think you want to know some nitro-way to do it :)

so long...

Subject: [Nitro] Can't set initialize for controller
Message-ID: <FDE577C0-B5D7-4C83-B61C-0BFAD90A38A5@gmail.com>

Good Morning,

So, I'm just starting to write my first Nitro app, and am a little  
stumped by this. I have a default controller (Nitro.run Game).  
Everything's just peachy until I define initialize for that  
controller, which seems to be a normal thing to do. Nitro throws  
errors like this:

ERROR: Error while handling '/'.
ERROR: undefined method `session' for nil:NilClass
   /usr/lib/ruby/gems/1.8/gems/nitro-0.22.0/lib/nitro/render.rb: 
167:in `session'
   /usr/lib/ruby/gems/1.8/gems/nitro-0.22.0/lib/nitro/flash.rb:82:in  
`flash'
   (eval):5:in `index_action'
... etc

ideas? pointers?

Thanks, Peter

Hello,

You probably have to call super from the initialize method.

Subject: [Nitro] [ANN] Nitro + Og 0.23.0 Scaffolding reloaded, Taggable,
	Nano/Mega integration...
Message-ID: <afd80b5405083108491d22a814@mail.gmail.com>

Hello everyone,

New versions of Nitro (Web Application Framework) and Og (Object
Relational Mapping) were released:

Homepage: http://www.nitrohq.com
Download: http://rubyforge.org/projects/ nitro
Mailing List: http://rubyforge.org/mailman/l istinfo/nitro-general 

The summer vacations are over and there is a brand new Nitro 
release. There is a preview of the new Scaffolder (also handles
Og relations), support for Tagging (folksonomy), lots of small 
features and improvements and many bug fixes. Additionally, the 
code has been restructured to utilize the excellent Nano and Mega
support libraries.

Most notable additions:

* Scaffolding reloaded. The scaffolding infrastructure is 
reimplemented to generate more flexible code. The automatically
generated forms allow for visualization and editing of 
Og relations such as HasMany and BelongsTo.

For example when rendering a BelongsTo relation all possible 
parents are presented with a select element. When rendering a 
HasMany relation a list of all children is presented.

Moreover, an experimental admin component is provided. Just add the
line:

require 'part/admin'

and surf

http://www.mysite.com/admin

To enter a simple administration screen. 

WARNING: This feature is considered a preview and will be 
improved in a future version.

* Major cleanup in the Glue subproject. Some files are moved
to the nano/mega project. Nano/Mega is now used throughout 
Nitro and really makes development so much easier.

* Introduced Og Taggable mixin. It was never easier to add
tagging to your application.

  class Article
    include Og::Taggable
    ..
  end

  article.tag('navel', 'gmosx', 'nitro')
  article.tags
  article.tag_names
  Article.find_with_tags('navel', 'gmosx')
  Article.find_with_any_tag('name', 'gmosx')

  t = Article::Tag.find_by_name('ruby')
  t.articles
  t.articles.count

For an example usage of this Mixin, consult the Spark sources.

* Added support for relative and absolute URLs in redirects
and renders. This feature simplifies the creation of reusable
components.

* Support for assigning compound objects from the request. Here 
is an example:

  class Article
    property :title, String
    property :body, String
  end

  <form>
    <input type="text" name="article.title" />
    <input type="text" name="article.body" />
  </form>

  article = request.assign('article')

Alternatively you can use the article[title] article[body]
notation.

* Added simple Benchmarking mixin.

* Added support for 'evolving' a single Og managed class. Useful
when you are in development mode and change your schema.

* Added support for session garbage collection.

* Many many small bug fixes in Og and Nitro.


Nitro provides everything you need to develop professional Web
applications using Ruby and Javascript. 

Nitro redefines Rapid Application Development by providing a 
clean, yet efficient API, a layer of domain specific languages 
implemented on top of Ruby and the most powerful and elegant 
object relational mapping solution available everywhere. 

Nitro is Web 2.0 ready, featuring excellent support for AJAX, 
XML, Syndication while staying standards compliant.

Nitro gives choice to the developer: Multiple paradigms are 
implemented, incorporating ideas from Rails, CherryPy, Catalyst, 
Wee, PHP, JSP and Microsoft.NET and more. The developer is free
to choose the pattern that better fits his application. This 
kind of freedom makes Nitro applicable to a wide range of 
applications, spanning from big, scalable web sites with thousands
of concurrent users to simple solutions for deployment on intranet
desktops.

have fun :)

Subject: [Nitro] [ANN] Nitro Spark 0.5.0 Tagging support
Message-ID: <afd80b54050831085346ca54fb@mail.gmail.com>

Hello everyone,

I am proud to announce a new version of Spark.

Spark is an advanced Wiki powered by Nitro and Og. The aim of
this project is to provide a canonical example of using Nitro
to build a Web application. 

An older version of Spark powers www.nitrohq.com

Homepage: http://www.nitrohq.com
Download: http://rubyforge.org/projects/ nitro

The highlight of this release is Tagging support. Moreover, the code
is updated to be compatible with the latest Nitro/Og release.

have fun,
George.

Dear devs,

Nitro 0.23.0 was kind of rushed in order to support the release of a
bigger nitro example.
This release will follow tomorrow. However, I suggest updating to the
latest version as it
contains numerous bug fixes.

regards,
George.

so this is why nitrogen is broken?
maybe it's some fault of my nano-installation, but i just did a 'gem 
update nitro' and said yes to every dependency
what makes me wonder is 'nano/dir/recurse'...

Nah, it seems to be a bug in nano (one of the deps) and I've already
reported it on Rubyforge. It's a real shame, because without this bug
Nitro 0.23.0 would already be in the unstable tree. I had all ebuilds
ready ca. 1 hour after the release...

Cheers,
Michael

The name of that method changed in Nano b/c it is a class method not
an instance method (I had to draw some sort of distinction) To require
it "in the raw" it should be:

  require 'nano/dir/%3A%3Arecurse'

And that's probably how George will do it. But to be thurough, one
could also use a built-in URI-escaping require:

  require 'nanoreq' # if not already loaded
  require_nano 'dir/::recurse'

I think George is off for the day, so he'll fix tomorrow. In the mean
time it shouldn't be too hard to find and fix manually.

Stupid me, now that I look at the hex codes, I see that they are :!?,
viz. characters which aren't all that strange in Ruby method names...

Thanks for pointing this out, it makes a lot more sense now. :)

Cheers,
Michael

No, it's going to be javascript.
