...ave children. Pretty standard so far. Often a child tag will be under more than one parent (i.e. a child might belong toone or more parents) and it wouldn''t necessarily have the same children under one parent as it would in another. Do and of the current extensions (acts_as_tree, acts_as_nested_set, awesome_nested_set, etc) let a child have more than one parent? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Using acts_as_tree, is it possible to get information of the depth a tree leaf in relation to the root? Or is available to derive information to save in the way "position" can be derived and saved for acts_as_list. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi Railers, Is the nested set model restricted to only one root? I''m working on a screencast building a threaded forum and nested set comes close but is lacking a few items for this project. First, all the documentation I can find restricts a nested_set to one root node, and a threaded forum would have many roots. Also, without a ton of fancy sql or an ungodly amount of db calls, it doesn''t track the depth. Is my understanding of nested sets correct? I created an acts_as_threaded to get around these "limitations" which perform...

Hi, has anyone successfully used the acts_as_threaded plugin with postgresql? I''m using rails 1.0 and ruby 1.8.4 on linux. Following the screencast on http://www.railtie.net/articles/2006/02/05/rails-acts_as_threaded-plugin , I got to where we''re ready to create our first post, having made the changes to controllers/posts_controller.rb, views/posts/_form.rhtml,

I''m trying to enhance acts_as_nested_set. Well actually I already have, but I''ve done a hack up job of it. I would like to contribute these enhancements back, but I need a little help. I''m a complete newbie to this stuff. The only thing I new before coming into this project was vanilla HTML. So over the course of tw...

Where can I see the API acts_as_nested_set constructs? I''ve read its page in api.rubyonrails.com but I don''t see how to manage the tree from there. -- fxn

Hi I was wondering if acts_as_nested_set can be used safely with concurrently updates? The fact that so much of the tree needs to be rewritten on inserts concerns me. Is anyone actually using it. I noticed that the status of acts_as_nested_set was unclear at the time the rails book was written. Regards, Glen

Hello, I''m currently using the gem ''nested_set'' for comment threading. What I want to do is prevent the comment level from going more than 2 levels deep. What I tired doing was something like this: class Comment < ActiveRecord::Base .... before_save :ensure_max_nestedset_level private # We d...

...s_tree :order => "name" belongs_to :catagory, :class_name => "Category", :foreign_key => "parent_id" has_many :sub_category, :class_name => "Category", :foreign_key => "parent_id" Which seems right I know that acts_as_nested_set has the ability to traverse through the structure but everything I hear says not to use it yet. My question is more or less can I till use it''s methods? Should I? Or would the best practice be to write a helper for this? I am a bit new to Rails but this is really stumping me, or...

Hello, I''m working to install the acts_as_commentable plugin on my Rails 3 app. After adding "acts_as_commentable" to my book model, I then added a comment form on my book show view: <% form_for(@comment) do|f| %> <%= f.hidden_field :book_id %> <%= f.label :comment %><br /> <%= f.text_area :comment %> <%= f.submit "Post

I''m desperate. A few hours ago I was checking my server because we are running a survey for a new client and everything looked good for that app but I noticed another Rails app was quite large (twice as normal) so I decided it was time for a restart. Big mistake. Upon restart the application gave me a 500 error. Checking the logs I found a stack level too deep error that after hours I
