I was at RailsConf Berlin and they were saying that they have a new  
process to get patches in.  I need to look up the info in more  
detail, but basically you need to have each patch verified by at  
least three people and it gets onto "Report 12".  I think that if we  
all hammer out something here and we're all happy with it, and  
especially figure out how to make it compatible with the old one it  
won't be an issue.

I like the idea of having an easy-to-use API built on top of  
something more powerful than what is currently in core.  I think with  
3 people working on this here (if Jean Christophe is interested) we  
should have no problems.

I am not quite ready to write/improve plugins myself. But I am getting
there. If you guys want an alpha tester, I could try out the new
integrated plugin and try to generate good issue reports.

Actually, I have a design question/suggestion for the current
betternestedset.

Quoting Will Schenk <wschenk at gmail.com>:
> What exactly is better about BetterNestedSet?  (I'm curious.  The
> move_to_child_of seems more complicated to me than just saying
> o.add_child, but having access to the level seems nice.)

Why is setting of parent_id directly prohibited? I have a before_save
filter that needs information from parent_id to work, but I can't set
it in the object. Wills post reminded me of the add_child method, so I
checked to see if that would prevent me having to do 3 saves to create
my object (the original save, the move_to_child_of save, and then an
additional, gratuitous save to get my filter to run), but I couldn't
actually get it to work at all. 

If it is neccessary to protect setting parent_id, is it possible to
put in some sort of registered callbacks? I am thinking of the code I
noticed in attachment_fu that lets you configure a block that is
called before a thumbnail is saved. It made it really easy for me to
add some metadata to the automatically generated thumbnails before
they were saved to the database. Example: 

  before_thumbnail_saved do |record, thumbnail| 
    thumbnail.title = record.title 
    thumbnail.description = record.description 
    thumbnail.user_id = record.user_id 
  end

Newbie,

Doing a site map type structure, as I'm sure many of you have too ..

Need breadcrumbs and to do lookups on a node by full path e.g


(home)/about_us/our_mission

and

Home / About us / Our mission

for example (assuming Home is the label attribute, of a model Menu)

Also anyone caching entire menus in a instance var ? Any advice?



Thanks Justin

Hi,

Iirc, the idea behind all this was to avoid breaking AR logic.
In AR objects, setting a property value doesn't save the object,  
neither does it save or change magically other objects of the same type.
Due to the way nested set works, moving a tree impacts more than  
setting a property value.
We preferred to have a heavy explicit method to be used than magic  
doing some changes in the background.

Hi,

Thanks Krishna for your summary !
I'm quite busy these days and won't be able to improve BNS just now,  
but I plan to continue to use it and I agree that merging is a good  
idea.

hi all!

I am now reading the recursive menu example and got some problem with the
code below:
------------------------------------------------------------------------------------

@menus[i] = {:indent => allmenus[i].level,
                     :title  => allmenus[i].title,
                     :children_count => allmenus[i].all_children_count,
                     :url  =>  allmenus[i].page ?
allmenus[i].page.whole_url : ''}

--------------------------------------------------------------------------
but in the database section, I dont see the column definition of
'title' and 'page', so is there somthing missed or
is it my misundstanding?

Patch is against r77.

In current version of plugin #destroy'ing tree nodes causes it to be
actually destroyed twice. This means that after_destroy callbacks will
also be called twice.

The patch fixes it.

betternestedsed does not work. This patch fixes this.

But note that this will not work with previous versions of rails, so you
most probably won't apply it as is. At least you can save time making

    The title and page are simply example fields.  The page is probably 
a table join like this:

class Menu
    has_one :page
end

... and Page has the property of whole_url.  You will need to modify the 
code to suit your layout.  This threw me for a long time too since I 
started using this plugin when I first started to use Ruby and Rails.   
I suppose the documentation could be a little clearer on the use of 
these variables.

Do you know this:
http://dev.oriontransfer.co.nz/SortableTree/

If you can adapt it to nested_set, propose to commit it here ;-)

Subject: [Betternestedset-talk] Ordering .roots
Message-ID: <959562ce0710101200m66306b6ay2d48067c94faefe5@mail.gmail.com>

So I'm calling my nested set model via an association that has an :order
attribute to it. This seems to be getting ignored and is using "ORDER BY
lft"...

but all roots will have a lft of 1, so its really no order. Should I just
bypass using .roots and add another association and set the conditions as:
parent_id = 0 OR parent_id IS NULL  and then the proper :order i need? Or is
there another solution I am overlooking?

thanks..

Subject: [Betternestedset-talk] acts_as_tree migration
Message-ID: <6253C6BC-7E40-4B05-BF7A-CCBF66766BC4@conradchu.com>

Hi,

I currently am using acts_as_tree.

I read in an old post (can't recall which one) that it's somehow  
possible to convert the acts_as_tree by adding the lft and rgt  
columns and running a "method" to pre-populate them.  Is that even  
possible?  If so, can some give me a clue as to how it's done?

Thanks!
Conrad

Hey Conrad,

This should be documented better, but it is actually pretty easy.
1) run a migration to add lft and rgt as integer columns to your table
2) put acts_as_nested_set in your model
3) on script/console run YourModel.find(:first).renumber_full_tree

If you have multiple trees in your table, it is a little more
complicated. You first need to give each tree scope (add a tree_id
column) and then run the above method on a member of each tree.

If you want to go back to a plain old tree, all you need to do is run
the migration back down and remove acts_as_nested_set from your model.

Hello,

It is a replacement of Aleksey Kondratenko patch, using 'attr_readonly'  
instead of overriding of 'readonly_attributes' method, with this change all 
tests pass. It also modify the test 'test_protected_attributes' to work with 
Rails 2.0.

Message-ID: <9e9015d40710161510g7b8aee5dh7164328910235131@mail.gmail.com>

Hi all, I'm doing something you all probably have done 100 times..

I've a cms type system with nested pages

eg.

http://www.example.com/about_us/mission_statement
http://www.example.com/our_products/myshinything
http://www.example.com/our_products/myshinything/large

My Page model acts_as_nested_set, and has an attribute slug, in the above
example we have  a page with the slug "mission_statement"  with parent page
with an attribute "about_us". I need to look up Pages by the full path e.g.
Page.find_by_path("about_us/mission_statement"), what is the best way to
deal with that ? Can I save the ancestors.slugs / fullpath saved in the
database somehow? Or other suggestions..

Hope that makes some sense ???

Here is how I deal with paths: in my controller I have a dispatch  
method that I get called by my route.
The idea here is simply to load pages one by one, begining with the  
first url segment.
If a segment is not a good page 'slug' as you call it (it's page.url  
for me) I default to the portion of the path already processed.
Given the fact that most of times url are not more than 3 or 4  
'slugs' deep, and that rails + db can cache repetitive similar  
requests, I think that the overload is worth the simplicity.

   def dispatch
     if params[:url].nil? or params[:url].empty?
       url = []
     else
       url = params[:url].map{|l| l.gsub(/[^a-z0-9_\- 
\.]/,'')}.delete_if{|l| l.empty?}
     end
     @page = Page.root
     if @page.nil?
       render :text => "<h1>404</h1><h2>No such page.</h2>", :layout  
=> true, :status => 404
       return true
     end
     url.each { |u|
       next_page = Page.find_by_url(u, :conditions => ['parent_id  
= ?', @page.id])
       if next_page.nil?
         break
       end
       @page = next_page
     }
   end


Hope it helps !

Subject: [Betternestedset-talk] attributes_with_quotes error
Message-ID: <471F0776.20904@munat.com>

To work with the latest Edge Rails (8009 as of this writing), this:

<lib/better_nested_set.rb:1093>

def attributes_with_quotes(include_primary_key = true) #:nodoc:
   attributes.inject({}) do |quoted, (name, value)|
     if column = column_for_attribute(name)
       quoted[name] = quote_value(value, column) unless
         !include_primary_key &&
         (column.primary ||
           [acts_as_nested_set_options[:left_column],
           acts_as_nested_set_options[:right_column]].include?(column.name))
     end
     quoted
   end
end

Must be changed to this:

def attributes_with_quotes(include_primary_key = true,
     include_readonly_attributes = true) #:nodoc:
   quoted = attributes.inject({}) do |quoted, (name, value)|
     if column = column_for_attribute(name)
       quoted[name] = quote_value(value, column) unless
         !include_primary_key &&
         (column.primary ||
           [acts_as_nested_set_options[:left_column],

acts_as_nested_set_options[:right_column]].include?(column.name))
     end
     quoted
   end
   include_readonly_attributes ? quoted : remove_readonly_attributes(quoted)
end

Sorry for the wrapping.

Subject: [Betternestedset-talk]  before_update problem
Message-ID: <18B16D7F-659C-4E25-B54A-15DB0FD63BA7@gmail.com>

Hi ,

	I relaunch the question about before_update. Actually, I develop,  
with other people, a rails application
and I use the plugin BetterNestedSet. But we can't use the callback  
before_update because of overwriting of
method update by the plugin.
	In addition, the before_create and before_destroy method are defined  
in the plugins, so the user
can't define them.
	Before trying to correct these problems, we would like know if you  
have solutions or if you will
make solutions in a near future.
	By example, we had thought to use class methods before_create and  
before_destroy like that:
before_create {...}, instead of overwrite them.
	We would like contribute to the plugin development and, for example,  
help to make solutions
of these problems.
	Finally, we create a non-recursive method to delete a node of a  
tree, move its children and renumber
  node's left and right column. So, we would like give this method to  
the plugin project.
	Thanks for you help and your understanding.

Sincerely yours,

I was just attacking this in an app today....

First step was finding something that would be able to move a page left or
right within it's siblings (ie, not change level yet) I made this but for
the life of me can not figure out why it is not working:

  def move_higher
    list = self.self_and_siblings
    index = list.rindex(self)
    self.move_to_left_of list[index - 1] if index > 0
    self.save!
  end

Anyone have any insight?  I have been looking at it too long.

Basically, you use this on an instance of page.  Like page.move_higher.
Idea is to move it up if it is not the first child and shift all others down
one.

Regards

Mikel
