All:

I am trying to create a query using rails and I am not quite sure how
to do it. I could get this done using plane old sql with no problem
and was even planning on doing that until I ran into a little issue
with find_by_sql. It seems that this does not preserve order.

What I need using Rails Active Record is the following:

I have a series of tables as follows:

tickets <habtm> users

tables here:

tickets
tickets_users
users

I also have:

users <habtm> roles

tables here:

users
roles_users
roles

What I need is a query where I can filter by roles. Essentially saying
... give me all the tickets for users whose role is 'foo'.

Thanks in advance,

Alfredo

Start from the role, then traverse to the tickets:

Role.find_by_name('foo').users.map(&:tickets).flatten

You could pull back the user objects with all the tickets attached.

User.find :include => {:tickets, roles } :conditions => "roles.name =
'analyst'"

for:

Bob
  -ticket 1
  -ticket 3
Jim
  -ticket 2
  -ticket 4

I'm not sure what order you are trying to preserve.

I would marry that method chain.

Subject: [raleigh.rb] Ruby extensions?
Message-ID: <3B1DC019-FEDF-4D89-9D5B-9D0321D65CCA@gmail.com>


I am having an issue with a Ruby extension I wrote. I pass the  
extension ASCII and it runs DES-ECB to encypt the data. The data comes  
back as a series of characters.

However, since the data it is being treated as a string in Ruby and it  
includes (sometimes) NULL characters, Ruby is truncating the data  
whenever I try to manipulate it.

Any ideas? Has anyone written an extension that returns bytes?

I haven't written one that uses bytes, but did do some with arrays a 
while ago.  As I recall there is some strangeness between getting the C 
and ruby sides to agree on types.  Have you tried sending the data back 
as an array instead of a string? You might also want to double check how 
you are casting things on the C side. I remember it not being really 
obvious how to get it setup.  I remember looking through the header file 
to see what else was available from a type standpoint, not sure if that 
would help.

I had to put this on hold and do something else and just got back to
it now. Thanks so much for the help guys. I was able to use both ideas
and based on what I needed created the correct query.

Appreciate the responses.

Message-ID: <9D1C39ED-1456-4365-ADE1-FA192CC2E80E@bclennox.com>

Hey list,

This seems like it would be a common pattern, but it's not quite  
making sense to me. I'm gisting some example code here:

   http://gist.github.com/61064

I have a single Address model that I'd like to use for any other model  
that might have an address, say Event and Contact. This means that  
Events and Contacts have to reference Addresses, so they contain the  
address_id column in the database and the belongs_to declaration in  
the class (which is where it starts to feel weird to me).

I build my form appropriately and call  
@event.update_attributes(params[:event]) in the controller, and I get  
an AssociationTypeMismatch ? Address(#31131890) expected, got  
HashWithIndifferentAccess(#9690560).

Am I approaching the problem incorrectly? It makes more intuitive  
sense to me that an Event has_one :address, but the docs say that the  
model with the foreign key must contain the belongs_to declaration. At  
any rate, I feel like the code I have should be working and it's  
probably something really simple to fix it.

Thanks!

Brandan L.

This is exactly what I wanted! I just didn't know what it was called.  
It's even the example on the wiki.

Yeah, I think the polymorphic association would be a good idea, but that
doesn't really solve his problem.

If you're on edge rails, then check out
this<http://ryandaigle.com/articles/2009/2/1/what-s-new-in-edge-rails-nested-attributes>.
If not, then I would consider updating your form to not nest the address and
then explicitly create the address in your controller, like
so<http://gist.github.com/61404>
.

I'm sure there's probably a better way to do the object creation in the
controller (perhaps a transaction), but this should be enough to get you
moving forward.

I think the problem that you're running into is what is solved by the  
nested model support in edge (and 2.3) rails:

http://weblog.rubyonrails.org/2009/2/6/this-week-in-edge-rails

You're model is expecting to recieve an ActiveRecord object as  
an :address attribute, not a hash, and that is why it blows up.

Without the nested form support, I've always had to write stuff like:

class Event < ActiveRecord::Base
   def attributes=(attrs)
     address_attributes = attrs.delete(:address)
     address = self.address || Address.new
     address.attributes = address_attributes
     attrs[:address] = address
     super attrs
   end
end

But that stuff goes away with the nested form support. So you're not  
doing anything wrong, you're just coding for the future!

Seems to me that this makes each address instance have a 1-1 relationship
with 1 event or contact or...

So, if we had multiple events at the same address, there would be an address
row for each of those event, in which case I'm not sure what's gained by
having a separate address model.

In this simple case, I'd consider just moving the address fields to the
event and contact models, perhaps considering STI for those two models if it
makes sense.

If preserving the identity of an address is important, then I think that we
might need to get into a join model or two, which probably gets Brandon
further away from his original problem of ActiveRecord not recognizing the
nested hash as being a nested model attribute.

You're right. I have two different problems. Polymorphic association  
seems to solve the first problem. Nested model support looks like  
it'll solve the second. I'll try to move to edge later this week.

Thanks!

We have at least 5 models that reference addresses, possibly more in  
the future, so I was trying to keep from duplicating address fields  
all over the various other models. I was also trying to use the  
Address model for helper-ish methods like address.to_s, but now that I  
think about it, I could probably stick those in a module and mixin to  
the appropriate models.

I did get my extension to work, although I have one test case that is  
a strange anomaly.

I used SWIG to generate the framework for the extension. One of the  
SWIG type maps allows you to pass a string, but SWIG in turn counts  
the actual bytes -- different than passing a string where a NULL  
character would terminate the string abruptly -- and calls C with a  
char * and the count of bytes. That does the trick.

And yes, when the data comes back, it has to be brought in as an array  
and unpacked.

I can post the solution if people are interested.

I *think* you can't modify the sub attributes individually though, but 
maybe that has changed.

Your idea of a module for the functionality and allowing duplication of 
fields/columns has much merit.

Subject: [raleigh.rb] RubyRX: Send five locally,
	and get five free passes to the DC RubyRX in September
Message-ID: <0DD45DA5-022E-417E-B8ED-581596603824@gmail.com>

Hi all,

We're offering a special to our local teams... if you send your team  
to Ruby RX here in Raleigh, you'll get free passes to the Ruby RX show  
in DC. It'll be this September 4th and 5th.

Btw, we've had to switch up the local schedule a bit. We've dropped to  
two tracks instead of three. We also thought we'd have to switch the  
venue, but we're back at the Marriott. No more drama, we promise. :)

The speaker list now includes Glenn Vanderburg, Chad Fowler, Yehuda  
Katz, Carl Lerche, Neal Ford, Kevin Smith, Nathaniel Talbott, Stuart  
Halloway, 	David Bock, Matthew Bass, and Rick DeNatale.

Let me now if you've got any questions!

Message-ID: <5fe6fa8f0902120748s1b8470a8m1c7921e7417b6617@mail.gmail.com>

Hello All:

So I have another question regarding associations. This one is very
closely related to a question I had a few days ago. I'll try to
describe it here the best I can.

I have the following tables. Please note that I am only mentioning the
relevant fields.

users
--------
id
firstname

roles
--------
id
name

roles_users
-----------------
user_id
role_id

tickets
----------
id
ticket_number
ticket_status_id


tickets_users
--------------------
ticket_id
user_id

ticket_statuses
----------------------
id

The issue I currently have that is creating all sorts of problems for
me is the following. I would like to list all the tickets with their
associated owners(users). As you can see from the tables above, a
ticket habtm users. What I end up with now using a sql query is a list
of tickets but with multiple rows for the same ticket since I could
have multiple users or owners for that record.

So I end up with: (fake table below, just used as an example)

---------------------------------------------
ticket id | description | owner
---------------------------------------------
1              foo             Alfredo
1              foo             RaleighUser

I could try to get a list of tickets, then iterate over those and find
out the users assigned to that specific ticket, concatenate them,
etc... and format the data. That's fine, most of the time. However
when I try to do pagination, dynamically filter by other ticket
properties such as status, ticket number etc... things get very ugly
very quickly.

So what I am looking for is the correct approach on how to handle all
these tables using the associations I've already created and end up
with a query that allows me to add conditions to it so I can do
filtering in a nice clean way.

I appreciate any help, guidance regarding this. I apologize for the long email.

Regards,

Alfredo

Ok, so I am very close I think to getting this to work. I currently have:

tickets = Ticket.find( :all, :include => [:users, :pvr_status, :priority] )

In there I can have the :conditions clause allowing me to dynamically
filter properties with a limit at the end for pagination. One last
thing to put it all together, how can I also add the roles into the
mix?

Thanks in advance,

Alfredo

Thanks Mark, appreciate it. I need to list based on tickets and most of the
filtering will be for ticket items. I think I've managed to get what I
wanted by having this.

tickets = Ticket.find(
   :all,
   :include => [:users, :ticket_status, :priority],
   :joins     => "LEFT OUTER JOIN roles_users on roles_users.user_id =
users.id LEFT OUTER JOIN roles on
                      roles.id = roles_users.role_id", :conditions => "
roles.name in ('analyst')"
)

I think this way I can add conditions dynamically in a nice clean way, at
the same time I can also handle pagination by throwing the offsets and limit
in there.

Please let me know what you think or if that query could be improved,
changed, see a problem with it, etc...

Thanks a bunch for the help.

Alfredo

you can use hashes or nested hashes in :include to eager load deeper
associations.

tickets = Ticket.find(:all, :include => [{:users => :roles} , :pvr_status,
:priority]

I don't think you need the joins clause, :include will generate the right
join for you.


tickets = Ticket.find(:all,
                             :include => [{:users => :roles},
:ticket_status, :priority],
                             :conditions => "roles.name in ("analyst")"
                             )

alternatively if you don't really need to instantiate the users, roles, etc
and only want the other table(s) joined to participate in the where clause
generated by conditions, you can use the same syntax in the :joins parameter

tickets = Ticket.find(:all,
                             :join => {:users => :roles},
                             :conditions => "roles.name in ("analyst")"
                             )

Very very cool, and very logical too. In fact I tried to achieve something
like that but with the wrong syntax. I am very happy to see that there is
way to simplify it even more, making the code more readable.

{:users => :roles} (That right there is really cool.) in conjunction with
the include statement.

Appreciate all the help guys.

As one final note, my own recommendation (perhaps after you come up with
something that works, and are ready for a new milestone) is to investigate
turning this kind of finder either into a named scope entirely or part of
its components into a named scope.  I have found those scopes extremely
powerful tools to expose expressiveness and power at minimal to low costs--
both development time cost and performance cost.

Cheers,

Jim

So here we go again, with another question. Btw, I hope it's not a problem
asking so many questions, I usually try to exhaust all my options before I
ask for help here.
So this time I would like to group by the ticket status, hence allowing me
to see a total count for the different types.

I have been trying to do this with:

tickets = Ticket.find(
  :all,
 :select => "ticket_statuses.name, count(ticket_statuses.name)",
 :include => [ {:users => :roles}, :ticket_status],
 :conditions => "roles.name in ('foo')",
 :group => "ticket_statuses.name"
)

The weird thing here is that my select is completely being ignored. I could
even put something else in there if I wanted to and it wouldn't even
complaint. It's simply bypassing it and not generating the correct query.
Select with no associations though works just fine.

I am sure I am missing something, just not sure what it is at this point or
where the issue is.

Any guidance/help is really appreciated.

Regards,

Alfredo

I think I found the answer in slide 14 of this presentation.
http://www.slideshare.net/RowanHick/how-to-avoid-hanging-yourself-with-rails

Ummm, that is interesting, so in this case, there is just no way to
accomplish a group by with a count using active record using a :select?

Query from my previous email:

tickets = Ticket.find(
  :all,
 :select => "ticket_statuses.name, count(ticket_statuses.name)",
 :include => [ {:users => :roles}, :ticket_status],
 :conditions => "roles.name in ('foo')",
 :group => "ticket_statuses.name"
)

Is there a solution, work around for this?

Thanks,

Alfredo

I knew there had to be a way to do this.
This seems to generate the query I wanted.

tickets = Ticket.count(
  "ticket_status.name",
  :include => [ {:users => :roles}, :ticket_status ],
  :conditions => "roles.name in ('foo', 'bar')",
  :group => "ticket_statuses.name"
)

Alfredo

There are lots of people who could use a more in-depth understanding of 
Ruby. So if your a Ruby pro, can develop a training outline, and like to 
help others learn please contact me. Lets get together and develop a 
paid training that will take people to the next level.

We recently held a training called Hands-On Erlang taught by Kevin 
Smith. It went really well. I'd like to reproduce this success with 
Ruby, Rails, SCRUM, Agile Dev, etc.

Thanks!

I can provide instructions on what to do.

Message-ID: <8308260d0902171134y35e8a9adwb4821292fcf4b23b@mail.gmail.com>

On occasion, our users will need to upload large files. We'd like a
progress bar to show the current status of the upload.

Googling shows me:
http://www.railsillustrated.com/screencast-file-uploads-progress-in-rails-passenger.html

And mentions:
http://mongrel.rubyforge.org/wiki/UploadProgress

and this, while referenced frequently, is 404ing:
http://sean.treadway.info/articles/2005/07/18/upload-progress-checklist

Any thoughts or suggestions? Am I missing something obvious?

We're running mongrel, so the UploadProgress plugin seems the first
choice for investigation.

Hey Matthew,

I'm interested in learning so I can apply it to the CVREG Meetings.

On ReverbNation, we use the upload_progress plugin for most cases:

http://agilewebdevelopment.com/plugins/upload_progress

It's reasonably easy to set up and use, and doesn't require too much
in the way of infrastructure to handle it.  It hacks in to
CGI#read_multipart and stores the progress data in the user's session.
 We use FastCGI in production, but I think it works with Mongrel,
although it might not be optimal in that case -- it might
unnecessarily tie up a Mongrel process while tracking an upload.

You might also consider SWFUpload, which does progress tracking on the 
client-side.

Thanks so much for the edifying and provocative talk, Aaron!

I was just thinking this morning how cool it would be if really big
third-party apps that want to consume a project, e.g. Spree, could be
isolated and authenticated with a CAS-based authentication service
like Castronaut.  Now if only said support were as ubiquitous as open
id...

We are in the midst of adding some credit card payment features on a  
project and one of my developers brought up something that hadn't  
occurred to me and posed a security risk for some projects we already  
have in production that accept credit cards. By default Rails logs all  
post data in production but its very easy to disable this from the  
controller.  Just thought I'd pass this to the group in case someone  
else had overlooked this as I did:

A thought:

In general, if you're thinking about integrating payment card processing,
stop and ask yourself if you can outsource this to a vendor with an API and
all the necessary storage in place... If you get successful, or make a
mistake, the costs of doing it yourself go up tremendously. If it's not your
core competency, double-think whether you want to write a line of code at
all... There is quite a bit more than worrying about logging sensitive data
to consider.

If anyone on the list is planning this type of work, feel free to ping me --
I'm just completing a several-month-long PCI DSS compliance project for my
current employer... expensive... I'd be happy to share thoughts and stories.

We have 7 years of experience with dealing with integration with  
payment processor gateways and indeed have learned a lot along the  
way. We use API's from Authorize.net and TrustCommerce and never store  
the credit card number on our server. Nonetheless I agree with you.  
Anyone thinking of taking on payment processing would be wise to  
consult with someone that has been doing it for some time. There are a  
lot of risks.

As an aside, it's not enough not to store the cards on your servers.   
If the card data ever passes through your servers on the way to the  
payment gateway's storage, your servers are required to be PCI  
compliant.  The absolute best solution if you don't want to deal with  
the nightmare of true PCI compliance (and who really does?) is to use  
a third party provider who has an offering that allows you to  
outsource even the capturing of the card number so that your servers  
never have access to the number, even when it's in transit.

An example of this is the Transparent Redirect service from Braintree:

It is a pain in the arse but I just finished PCI compliance with one  
server and it feels good to have complete control of the transaction.  
Worth it if you are doing heavy volume IMO.

I would like to see what an integration with the Braintree service  
looks like on a live site though.

Kendra,

	Hi. Depending on the details of the project, I might be interested if  
I could do the bulk of the work at home. Any reason the bulk of the  
development work needs to be done on site? Other than meetings and  
what not.

	This is me:

It's more than just accounting, but if you are a freelancer, you might want
to consider, as I'm doing at the moment,
Rothwell International. http://www.rothwell-international.com/home.html

Some might remember that they gave a pitch at the raleigh.rb meeting some
months back.

Basically, assuming that you are making anything reasonable as far as
revenue goes, they seem to provide some great financial benefits.  You still
need to find your own work, but you invoice clients through them. They give
you W2, rather than 1099 status as far
as the IRS is concerned, i.e. you are effectively their employee for tax
purposes, with a status kind of like a salesman whose income is 100%
commission with a 100% commission rate.  For $300/month for months in which
you have revenue they:

   * Withhold your personal income and self-employment tax payments, and get
them to the IRS on time.
   * Cover you with their liability, workmen's comp, and errors and
omissions insurance.
   * Allow you to charge business expenses (travel, lunches, office
supplies, ...) making them tax-deductible rather than personal income.
   * Allow equipment you buy with business income to be leased back again
making any income used to purchase it not subject to income tax.  They told
me that you still own the equipment.
   * Offer an option of Blue Cross/Blue Shield medical insurance.  Although
the rates seem similar to buying it yourself, there are supposed to be tax
advantages, since part or perhaps all of the premium can be charged as
business expense.  They also offer optional Dental benefits.
   * Optionally offer something like the Flexible Savings Account which
larger companies sometimes provide. This lets you set aside a certain amount
of tax-free money each year to be used for medical expenses.  They claimed
that unlike most of these accounts there is no "use it or lose it" aspect.
I'm not sure I completely understand exactly how that works.
  * Provide a W2 documenting all deductions at the end of the year.
  * Do your 1040 for you if you have had enough months of revenue billed
through them (I can't remember the exact number of months required).  This
make sense since they have all of your business related deduction info
already.

Now, I'm sure that most, if not all of this can be done by yourself, a CPA
and a lawyer to set up the right personal business, but this looks like it
might be less hassle free.  They seem to be quite willing to tailor their
services.  I learned yesterday that although there US Headquarters is in
Raleigh (the base company is South African), their current US freelancers
are all in Texas.  They seem eager to grow their business locally.

Since I'm still considering this, I'd appreciate any comments.

There are a number of offerings like that around, a friend of mine has
worked with one called iProfessional for years. My main issue with
them has always been that they seem very geared towards people who are
just doing consulting and I have aspirations to build a product (like
I am sure 95% of independent consultants do) and it seems like you
could end up with some potential issues around doing product
development while technically being an employee of that company. For
instance you will need a real business if you want to process credit
cards, shield yourself from liability, etc.

I use Paychex to handle all of my payroll taxes and a CPA to handle
the end of year stuff. I pay for insurance myself which sucks, but it
is all tax deductible. I pay for all expenses out of the business
account so accounting for them at the end of the year really isn't an
issue. Paychex charges about $70/month but it is worth it just not
have to deal with the monthly and quarterly forms and payments. I used
to do it all manually and I spent at least an hour a month doing it,
so Paychex was worth it.

Thanks Jonathan.

I also realize I should have put a little more context into my  
message. For those that may not know, MacRuby is the heir apparent to  
RubyCocoa and allows developers to use Ruby to do native (Cocoa)  
development on the Mac w/o the use of any bridging/brokering between  
Ruby objects and Objective-C objects.

The reason I ask about interest level is that I noticed about a 50/50  
split in Mac/PC use at the meetings and I'm not sure how everyone  
feels about platform specific talks.

Thanks,
Sean

RubyRX opens tomorrow night, and even if you're not coming to the
conference proper, you're still invited to come out to the
pre-conference mixer. It'll get rolling around 8 with a speaker panel,
and then there will be time for lightning talks starting around 8:30
(non-conference attendees are welcome to present lightning talks as
well). If you're not able to make the conference but would like to
come say "Hey!" to all the speakers, out-of-towners and locals, we'd
love to see you tomorrow!

When: Thursday, 2/19, at 8pm
Where: http://www.nfjsone.com/conference/raleigh/2009/02/travel.html
Who: Everybody!

Can't wait,

This may be archaic, but in the past I've built little static sites
with Rails, then just used wget against the locally running app to
extract a set of static files. I extracted the wget stuff into a rake
task. If this interests you at all, ping me and I'll put the rake task
in a gist or something.

I went ahead and gist'ed it up anyway. There's some app-specific stuff
in there, but tweaking it to fit a different app shouldn't be too
difficult:

I'm hoping to see http://github.com/fivepointssolutions/serve get more  
use. You use erb, haml, sass (HTML and CSS) and Ruby in a directory/ 
file structure similar to a Rails view directory, get helpers, render  
partial, stuff like that. Then, you do something to make something  
like the ServerController module's show method work in passenger  
(Nathaniel did some work with rack) so the ResponseCache (from  
Radiant) works like it does when you use that serve gem as a Rails  
plugin, then BAM! you've got super fast content.

Let me know if you'd like to know more. We need to get it packaged up/ 
tested a bit more and merged back into Serve proper...

I tinkered around with StaticMatic a few months ago:

It seemed useful.

I've had good luck with jekyll.   It's pretty flexible about what you  
can write in, and simple enough to get started with.

I like webgen (http://webgen.rubyforge.org/).
It is built around a  very flexible pipeline of filters your content can 
go through during creation.
Compared to webby, webgen has more useful features like a tag system 
similar to the one in radiant, and a auto-rebuild feature for quick 
testing as you build.

Subject: [raleigh.rb] Random massive memory usage on a VPS
Message-ID: <9316010E-85C5-4ED3-9682-302404A53C48@tonyspencer.com>

I'm stumped by this one and hope someone can give me some ideas on  
debugging it. We have one relatively low traffic rails app (~1150  
pageviews a day) running on a 1GB slice at slicehost.com: http://www.spainrealestate.co.uk

I have received 3 warnings via email from slicehost complaining  
"...your slice, spainrealestate.co.uk, is showing a considerable  
amount of consistent swapping activity..." and they are threatening to  
cancel the slice.  Everytime I ssh in the slice is happy as a clam:

root at spainrealestate:~# uptime
14:53:23 up 69 days, 23:26,  2 users,  load average: 0.00, 0.01, 0.00

root at spainrealestate:~# free -m
              total       used       free     shared    buffers      
cached
Mem:          1022        779        242          0        117         
227
-/+ buffers/cache:        435        587
Swap:         2047          5       2042

The slicehost support told me :

"From what I can see, your Slice's I/O usage is incredibly high:

Swap read rate: 868.5205, write rate: 1275.6448
Root read rate: 130803.8933, write rate: 65973.9669

Those numbers are "reads/writes per second."  Your Slice is making  
almost 131,000 reads and 66,000 writes per second - which is a very  
high number and could cause performance issues."


We are running Passenger and Rails 2.1. If I could somehow be notified  
by the server when it began to happen perhaps I could find some way to  
make my Mac blare loud music and wake me up so I could see what  
process was chewing up memory.

Oh and I've verified that we have no entries in any user's crontab.

I'd be grateful for any tips.


Finally here is what top sorted by memory looks like:

Check /var/log/messages or /var/log/kern.log for any processes that might be
getting killed for too much memory.  We've had that happen on some of our
VMs but mongrel gets restarted quickly enough that munin only notices the
PID changed.  After the fact everything looks honky dory like your system.
 Hardly any load.
Are you doing anything like using image_science to process images or
uploading big files like videos?

My suggestion is to look in your slice management panel and see if the 
slice is actually doing as he says (under statistics).  Sounds like a 
mistake to me!

You could setup monit to watch apache and your overall box. Monit can
send you email, restart processes etc when a process has reached a
defined memory or cpu limit. You could also try using ab or httperf to
simulate some load and test your setup.

Also maybe reducing the number of passenger workers would keep you
from swapping. You should have no more than N workers:
passenger_worker_memory * N = total memory - (memory used by other
processes).

No there currently isn't any image processing going on on this app.   
There are images generated occassionally when we pull in a feed of  
properties but that is rare and we initiate the rake task manually so  
I know when that occurs.

The slice is using less than half of its physical memory now. I guess  
I'm going to install this bash script to notify me when swap usage  
rises.  I really don't want to upgrade to 2GB at twice the cost.  I  
did read others complaining about high memory usage on these slices b/ 
c of the fact that they are all 64 bit at slicehost:

This is what stats say currently when I check them.  I still don't  
understand how that can be if I have roughly 600MB of free physical  
memory:

Diagnostics

     * Your slice is currently running.
     * The host server is up.
     * Your swap IO usage over the last 4 hours is high: 869.0001  
reads/s, 1276.3531 writes/s. (Read more about swap here)
     * Your root IO usage over the last 4 hours is high: 130876.76  
reads/s, 66013.7694 writes/s.
     * The host server's load is nominal: 0.18, 0.19, 0.10.


One thing that does come to mind: we have contact forms on each  
property that send email when filled out.  I have seen on some of my  
other sites that there are bots that fill in forms and sometimes  
rather ruthlessly. Perhaps there are large spikes from this.  I think  
I'll download access logs from apache and run them through an analyzer.

There is absolutely no way that your slice has done 130k writes/second  
and 66k reads/second over the last 4 hours.  If that's in bytes or is  
the number of I/O operations _in total_ over the last 4 hours, I can  
believe it, but not I/O operations per second.  The disk subsystems in  
their servers aren't fast enough to support those numbers otherwise.

Any recommendations for a tool/application that you have used to
create the entire project from scratch as part of the design process
(Design Document). Example: gui views details, database schema
description, NTH, MH, etc ...

What do you typically use when you need to design/architect a new site
from scratch?

Thanks in advance,

Alfredo

This might sound arcane but I've had great success over the past 2  
years by drawing interfaces on paper with notes about behavior  
highlighted. I then feed them in a multi page scanner and upload to  
Basecamp. The team meets via Skype to review the drawings and poke  
holes in it.

Next step, a developer designs the initial DB just by typing the  
models and columns and we meet once more to poke at it.

Next he loads the initial DB with migrations and begins developing the  
app around the drawings.

Finally my designer gets tickets assigned to him as views are  
completed and he makes them pretty as he has a Rails stack running on  
his design machine and understands basics about how to update from SVN.

I review and engage in back and forth with developer and designer  
until an interface is right and the ticket gets closed.

This may not be the cool way to do it but it sure has worked great for  
us.

Thanks very much for giving me this sanity check.  I'll bring it up  
with the owner. He has agreed to help me with this issue.

I'm not sure I follow, but perhaps in answering, some clarification  
will emerge:

- GUI views / HTML

I use BBEdit for generally everything text related. For my moonlit  
business, I build HTML for  my views, admin and public on a local  
virtual host. That leads into hooking up controllers and ERb pretty  
easily once I figure out how the app needs to act.

- Database schema

I use OmniGraffle to build a visual representation of my schema and  
relationships. An absolute joy to use.

- Notes / tasks

Since I'm working largely solo on the tech side, I keep misc notes in  
OmniOutliner and tasks in OmniFocus.

Nathan:

That's pretty much what I am looking for. To be more specific, I
currently use the following.

a) To get a general idea of what the application will do, I usually
start off with a white board.
b) Some of the stuff in the white board, ends up being mapped with FreeMind.
c) For my database I use MySql Workbench
d) The design document ends up being old M. Word with some images from
FreeMind, Database Schema and other information regarding the Design
Document.

What I am looking for:

An application that will allow me to do all that with a for example
pre-defined set of templates that will contain Design Document items
that are repetitive and applicable to all the projects I'll be working
on. To get an idea, check out:

http://readyset.tigris.org/nonav/templates/frameset.html

It's an open source project that allows you to re-use the same set of
templates for all your projects.

I was wondering if there is a tool out there that sort of combines all
these ideas and merge them all into a single application. Also
providing me with the ability to mock up some of my views and their
respective flows. The view won't look of course like the actual
finished product; but it would allow me to place things such as forms
for login, a grid, accordion layouts, etc ... Essentially allowing me
to sketch out the entire application flow.

Thanks for the response, appreciate it.

Phew.  Thanks again Mark. Looks like I have their attention now:

-------------------
Hi Tony,


I wanted to let you know that I am consulting with our developers on  
your issue (as those I/O numbers seem outragously high to me) to see  
if there is perhaps a bug in our system that may be affecting you.  I  
will let you know as soon as I know more.


Regards,

For design work involving UML diagrams, database schema, etc. I really 
like Magic Draw. After using it for a while, I found the UI to be 
intuitive and flexible. If you create many class diagrams, subtle 
differences in drawing tools can make a *big* difference.

It's written in Java so you can run on Mac OSX, Linux, Windows. I think 
I paid $129 for a personal version - worth every penny:

http://www.magicdraw.com/

I use it in "sketch" mode primarily for transferring design ideas to a 
visual form i.e. no roundtrip.

Tony looks like an error on our part. One of our lead admins and  
developers looked at it and the problem should be fixed, it has pretty

StaticMatic++

I've been using StaticMatic on a small project recently.  Its pretty
feature lite. If all you need is templates and layouts and helpers it
is quick to understand.  I like that it has a server mode so that you
don't need to rebuild to see changes.

Dave's Definitions: Morning, is after I've slept for more than four
hours. Lunch is the second meal of the day no matter the hour of
consumption. A long drive is one longer then you have last slept.
Ineffable, if you don't understand I couldn't possibly explain it.

Well I was going to send this just to Tony, but because of his email
address, I figured it wouldn't get through. <G>

I probably had a bit to do with this. Ben's a former colleague who went to
Slicehost. When I saw this thread I IMed him to see if he was aware of the
thread, and when he wasn't pointed him to the archives for the list.

Subject: [raleigh.rb] raleigh-rb-members Digest, Vol 39, Issue 18
In-Reply-To: <mailman.333.1235071670.18880.raleigh-rb-members@rubyforge.org>
References: <mailman.333.1235071670.18880.raleigh-rb-members@rubyforge.org>

Hello Alfredo,

I use gliffy.com, works specially well to plan the workflow of an App,  
but they also have html objects such as drop-downs and other user  
interface icons..
It is a flash app, so needs saving and refreshing after each update.

The drawing and scanner seems better, I just mention this because  
OmniGraffle was mentioned.  I switched from omnigraffle to gliffy for  
flowcharts because it was easier for collaboration.

cheers,
Jose

#!/ruby/rails/2.2.2

I am building a website where visitors can add bookings, but not list
them. I placed map.resources :bookings, :only => [:new] in routes.rb,
but I get a NoMethodError when I try to load the new bookings form.
The error happens on this line in the view: form_for booking do |f|

If I edit routes.rb to look like map.resources :bookings, :only =>
[:index, :new] everything is fine until I hit submit. Then I get a
weird ActionController::MethodNotAllowed error telling me that only
GET requests are allowed. Both the URL in the address bar and the HTML
for the form seem to indicate that the form is posting to the index
action. Why would it do that?

In case you need to know, I have removed the actions that I do not
require from the BookingsController. All that is left is new and
create and they are pretty much the same as when Rails generated them.
Can anybody help me with this or point me in the right direction? I've
looked on Google, but I haven't found anything.

You probably need to allow the 'create' action as well.

/bookings/new #=> the 'new' form
/bookings        #=> the form POSTs to this to create.

With what you've said so far, you don't need the 'index' action enabled.

Hi Raleigh friends --

By the power vested in me by his royal Talbottness, I am taking this 
opportunity to let you know about an upcoming 3-day Ruby training 
course, April 1-3, in Atlanta.

The instructors will be me, Jeremy McAnally, and Rick Olson. Between us 
we've written something like five Ruby-related books, trained several 
hundred developers, and written much of Rails (well, that would be 
Rick). You'll be in good hands.

Details and registration are here:

   http://www.entp.com/training/atlanta09

and I'll be very glad to answer any questions if you want to email me 
directly.

Thanks!


David

If you scaffolded the model , rails puts a cancel link back to the  
index in the new view. Removing that should make the no method error  
go away

I did scaffold the files, but I made sure the cancel link was gone.
Taking Steven's advise, my route now looks like map.resources
:bookings, :only => [:new, :create]. Now the error I get is below:

ActiveRecord::AssociationTypeMismatch in BookingsController#create
Province(#70175116095560) expected, got String(#70175161187320)

I checked BookingsController#create. The only thing I've changed was
the flash[:notice] for a successful save. Province, a lookup model, is
built as follows: <%= f.select :province, Province.all.map { |p|
[p.name, p.id] } %> This was based on an example I found online. Is
f.select wrong? It seemed to generate the correct markup for me.

Thanks for your help

If your model has_one :province, that's your problem.  province= is
expecting a Province model not the string that was matching.  If you make it
set the province_id, then it will work as it's probably getting the id as a
string and Rails will coerce that magically for you.
Should work: <%= f.select :province_id, Province.all.map { |p| [p.name, p.id]
} %>

In those cases, I like to use collection_select:

<%= f.collection_select :province_id, Province.all, :id, :name %>

I can never remember the ordering of the label/value in those option 
arrays, but for some reason, I always remember the ordering of this one.

I'm a fan of Curio.  Part diagramming, part mind mapping, part note taking.
 Makes for a good random dump for the stuff related to a new project.
I still do end up in OmniGraffle for diagraming somethings... I'm just used
to it and am faster with certain kinds of diagrams.

Omnigraffle here, but mostly because I couldn't find any other suitable
Visio replacement when I was involved more with network engineering.

Thank you all! It now works great! Seems I was sending the string id
instead of the Province object I was specifying. What is the
difference between f.select and f.collection_select? I was actually
using something like @provinces = [['Select', '']] + Province.all.map
{ |p| [p.name, p.id] } in my controller and then using <%= f.select
:province_id, @provinces %> in the view. If f.collection_select is
better, how would I add the blank option at the top of the select box?

One more question: where is the best place to change where the user it
sent when they submit the form? The generated create action has
format.html { redirect_to(@booking) }. Should I just modify that or is
there a better way to do it?

Have a look at the docs here:

http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html

I believe you can use the :prompt option for a "blank".

Yes, modify that.

I have this snippet in ApplicationController. So I can target specific

it safe as is?

before_filter :set_controller_and_action_names

This is potentially dangerous if an attacker were able to fool your  
application into accepting HTML as an id parameter. I don't know if  
it's possible, but it's not worth taking the chance. I personally  
don't consider this to be controller behavior, either. I typically put  
this sort of thing in a LayoutHelper.

If you're using Haml, there's already a page_class method that  
(essentially) replaces your @body_class instance variable. From the  
Haml source:

   def page_class
     controller.controller_name + " " + controller.action_name
   end

And if you were to use make_resourceful, the appropriate object is  
exposed through current_object, so your body id could use the id of  
the current object ? if one exists ? since that's guaranteed to be an  
integer in most cases:

   def page_id
     id = page_class.tr(' ', '_')
     id += "_#{current_object.id}" unless current_object.nil?
     id
   end

That may not be helpful, but this is the pattern I find myself using :-)

Brandon,

I agree with Thomas that the best place for this is in a view helper.  
I don't think it's all that dangerous though (I'm not sure of the  
bigger picture of why you need it, I assume you have a good reason).  
To  remove any of Thomas' concerns about HTML in the ID parameter, you  
can escape it and convert it to a number. No nefarious content will  
survive this:

@body_id = "#{@body_id}_#{h(params[:id]).to_i}" if params[:id]

Good luck,
Sean

Message-ID: <BBE24013-1CA1-414F-9175-91B69FD8689F@iannopollo.com>

This may be my brain not working at this moment, but I cannot seem to  
get the proper query I want to find some records.

Background info:

Merchant has many Specialties through MerchantSpecialties

I want to be able to find merchants by all the specialties they have.  
So right now my query looks something like this

select distinct merchants.* from merchants
   inner join merchant_specialties on merchants.id =  
merchant_specialties.merchant_id
   inner join specialties on merchant_specialties.specialty_id =  
specialties.id
   where (
     specialties.id in (1,2,3, etc...)
   )

This query works if you only want to find a merchant by one specialty,  
but potentially doesn't bring back the proper data if you select more  
than specialty (the "in (1,2,3)" finds merchants that have any of  
those specialties). I want to be able to find a merchant who has  
specialty 1, and specialty 2, and specialty 3; not find merchants who  
only have specialty 1 but not specialty 2 and specialty 3. Hopefully  
you see what I am trying to get at.

It feels like this should be an easy problem to solve, but my SQL  
skills are not helping me on this one. Thanks for any help!

 If you want to put it all in one SQL statement, you have to join
against merchant_specialities multiple times. Also if you don't need
any properties from specialties you can leave it out.

 So if you need to find a merchant with two specialities, you need a query like:

select merchants.* from merchants m join merchant_specialties ms1 on
m.id = ms1.merchant_id join merchant_specialties ms2 on m.id =
ms2.merchant_id
where ms1.specialty_id = 1
and ms2.specialty_id = 2

 For 3 specialties, you'd need to add "ms3" to the mix and so on.

A couple things.  First I think you probably need to use a directed join 
so that you return all the possible matches for one side of the join, 
and then use group by and having clauses to make sure that your merchant 
has ALL of the specialties.

Example:

SELECT merchants.*, COUNT(specialty_id) as specialties_count
FROM merchants LEFT JOIN merchant_specialties ON merchants.id = 
merchant_specialties.merchant_id
WHERE merchant_specialties.specialty_id IN ([insert your specialty ids 
here])
GROUP BY merchants.id
HAVING COUNT(specialty_id) = [insert the number of specialties here]

This should return only merchants who have those specialties (unless I 
flubbed up royally).

Now if you don't mind doing this in memory, you could do something like 
this:

merchants = specialties.map {|s| s.merchants }
first = merchants.shift
merchants.inject(first) {|acc, m| acc & m }

Looks like I found a solution after a bit of googling: http://answers.google.com/answers/threadview?id=567921

In the last post they show using "group by" with "having". I tried it  
out, and it apparently works! (I don't really know why it works, but  
am glad that it does :-)

So now my query looks like this:

select distinct merchants.* from merchants
   inner join merchant_specialties on merchants.id =  
merchant_specialties.merchant_id
   inner join specialties on merchant_specialties.specialty_id =  
specialties.id
   where (
     specialties.id in (1,2,3)
   ) group by merchants.id
   having count(distinct specialties.id) = 3

So, bonus points if anyone can tell me why this works (because I am  
still clueless as to why the solution works).

Thanks for the replies!

Right, the only difference is that I didn't join to specialties (since 
you're selecting by IDs, it's not necessary).

Can anybody tell me why this doesn't work?  I'm trying to cycle through some
images with jQuery and when I try to pass an argument to the function it
breaks.  I have all the images on the page with display set to none when the
page loads.
The following works but it only changes the image once because the variable
i is reset to 1 each time cycleFeaturedProperties is called.

function cycleFeaturedProperties(){
 // Cycles the featured properties on the home page
var i = 1;
jQuery("#" + i).fadeOut(200, function(){
 i++;
jQuery("#" + i).fadeIn(200);
});
 if (i == jQuery(".feature").length) {
i = 1;
}
 window.setTimeout(cycleFeaturedProperties, 3000);
}

function showFirstProperty(){
jQuery("#1").fadeIn(200);
}

jQuery(document).ready(showFirstProperty);

window.setTimeout(cycleFeaturedProperties, 1000);



When I try to pass i back to the function the whole thing breaks and does
nothing.  The actual change that causes the break is
window.setTimeout(cycleFeaturedProperties(1), 1000);  I've also
tried window.setTimeout(cycleFeaturedProperties("1"), 1000); but it makes no
difference.

function cycleFeaturedProperties(firstId){
// Cycles the featured properties on the home page
var i = firstId;
 jQuery("#" + i).fadeOut(200, function(){
i++;
jQuery("#" + i).fadeIn(200);
 });
if (i == jQuery(".feature").length) {
i = 1;
 }
window.setTimeout(cycleFeaturedProperties(i), 3000);
}

function showFirstProperty(){
jQuery("#1").fadeIn(200);
}

jQuery(document).ready(showFirstProperty);

window.setTimeout(cycleFeaturedProperties(1), 1000);

Or leveraging ActiveRecord a bit more:
Merchant.find(:all, :select => "*, COUNT(speciality_id) as
specialities_count", :joins => :merchant_specialities, :conditions =>
"merchant_specialities.speciality_id IN(1,2,3)", :group =>
"merchants.idHAVING COUNT(speciality_id) = 3")

Hi,
I think the problem is that the callback cycleFeaturedProperties is  
the name of a function while cycleFeaturedProperties(i) becomes a  
function call.  It is executed immediately with the result is being  
used as the callback.  I believe passing it as a closure should work:

window.setTimeout(function() { cycleFeaturedProperties(i) }, 3000);

Ok, I think I'm on the right track now.  Here is the code I have.  Its
getting the job done but the pictures are changing really fast regardless of
the delay I set on window.setTimeout
function cycleFeaturedProperties(hide, show){
// Cycles the featured properties on the home page
jQuery("#" + hide).fadeOut(200, function(){
if (hide == jQuery(".feature").length){
hide = 1;
}else{
hide++;
}
jQuery("#" + show).fadeIn(200, function(){
if (show == jQuery(".feature").length) {
hide = show;
show = 1;
}else{
show++;
}
window.setTimeout(cycleFeaturedProperties(hide, show), 10000);
})
})
}

function showFirstProperty(){
jQuery("#1").fadeIn(200, function(){
window.setTimeout(cycleFeaturedProperties(1, 2), 10000);
})
}

jQuery(document).ready(showFirstProperty);

Actually, I just tried this, and although it generates the same query Sean
suggested, it doesn't work  this does:

Merchant.find(:all, :joins => :merchant_specialities, :conditions =>
"merchant_specialities.speciality_id IN(1,2,3)", :group =>
"merchants.idHAVING COUNT(speciality_id) = 3")

The original with the select option was returning a Merchant with an
artificial id.  The COUNT(speciality_id) as specialties_count doesn't seem
to be necessary.

I don't use jQuery, but I've enjoyed using LowPro for abstracting these 
types of behaviors.  You might find "LowPro for jQuery" useful.

Sean, thanks for that.

I've been looking at a project which would require jquery, and I was
wondering if there was anything like lowpro for it.

I guess that there is!

Nice. For what it's worth, we're using some similarly hard-won jQuery  
lines to do just about the same thing. With a little trepidation but  
also knowing that it's good to read other people's code, here it is:

http://github.com/amanikids/website/blob/ 
9f3b96b56cb5c28c63176187737755c916f1857a/public/javascripts/ 
application.js#L48-73

(The behavioral difference, purely a matter of taste, is that we fade  
an image in over the top of its predecessor without first fading out  
the predecessor. We were also playing with attaching functions  
straight onto dom elements.)

Cheers,  -- Matthew

Message-ID: <49A56CFD.6070808@smokejumperit.com>

Using the built-in functional testing for Rails, how do I test that if the flash is set, then a 
redirect happens to an action, that the action renders the value of that flash to the screen?

Trying to set flash[:val] before calling get or post results in a "Cannot convert integer to String" 
error.

flash is a proxy to the internal flash inside the controller. Accessing it
before a get/post won't work.
Try something along these lines...

def test_flash_redirect
  get :index
  assert_equals 'foo', flash[:val]
  assert_redirected_to :action => 'new'
  follow_redirect!
  assert_tag 'p.flash', 'foo'
end

I've been in RSpec/Cucumber land for awhile, so I can't swear that
follow_redirect is available in a functional test. You may need an
integration test. I know that it *won't* work if you are crossing controller
boundaries.

The Ruby.MN list came up with the solution -- "get" takes the flash in its call.

The way we'd test this is:

def test_flash_is_set
  get :index
  assert_equals 'foo', flash[:val]
  assert_redirected_to :action => 'new'
end

def test_flash_is_displayed
  get :new, {}, {}, {:val => 'foo'}
  assert_tag 'p.flash', 'foo'
end

The third hash passed to a request method (get, post, etc.) represents
the contents of flash.

Subject: [raleigh.rb] Dynamic chaining of named scopes?
Message-ID: <1F99B23E-07FA-48A3-8131-B3EA962F1DA4@bclennox.com>

I'm trying to implement search based on a variable number of  
parameters, like min_price, max_price, etc. I thought it would be neat  
to set up named scopes for each of those parameters, and then in a  
class method, dynamically chain them together based on the parameters  
passed to that method. I tried this:

   named_scope :min_price, lambda { |price| { :conditions => ['price  
 >= ?', price] } }
   # and so forth...
   def self.search(params)
     scopes.keys.select { |s| params.key?(s) }.inject(all) { |memo,  
scope| memo.send(scope, params[scope]) }
   end

but when I try:
   search(:min_price => 50, :max_price => 1000)

Rails says "NoMethodError: undefined method `min_price' for #<Array: 
0x35a5084>". Apparently named scopes don't work like I think they do.

Even if this is a stupid way to implement search, I'm curious if it's  
possible. Any help?

Well, I just found Squirrel, which looks like it's better for this  
than anything I could write or will ever write...

use inject(self) instead of inject(all)

Thanks Brian. That makes perfect sense.

Subject: [raleigh.rb] rails routing quiz -- contributions welcome
Message-ID: <0CA49B7B-7074-4B3F-94CE-71C89B5AFDEB@gmail.com>

Hi, all --

Consider this a Friday "Ruby Quiz", except it's quite Rails-specific.

In essence, I'm looking to get this test to pass:
   http://gist.github.com/71344

I'm on a quest to make my sign up urls look prettier, and I want  
config/routes.rb to be the *only* place that has to change -- not my  
named route calls, not my AccountsController. This should be purely a  
routing concern.

I've written the test with minimal dependencies, so you should be  
able to
   $ git clone git://gist.github.com/71344.git gist-71344
   $ ruby gist-71344/routing_test.rb

regardless of your rspec/shoulda/etc. preference.

Thanks! Have fun!  -- Matthew
