similar to: using :include with acts_as_tree?

I am struggling with how to do eager loading of an acts_as_tree model. If the model Stuff acts_as_tree I know I can do this to get children as well: Stuff.find(:all, :include => :children) But what if the model I am including is the one that acts_as_tree? For example, say Picture belongs_to Category. Category acts_as_tree and I want to get all pictures that are members of a category that

I have a model using acts_as_tree which is working fine. Being new to Ruby I''m don''t know what enumerator is best to use for traversing a tree by depth. I can write one, but before I do I wanted to know if there is there an enumerator for traversing trees available that the community recommends?

Hey guys and gals, I have the following object that has acts_as_versioned: class Note < ActiveRecord::Base acts_as_versioned belongs_to :user end The schema for my notes table is as follows: create_table :notes, :force => true do |t| t.column :id, :integer t.column :noteshare_id, :integer t.column :user_id, :integer t.column :title, :string

Will the find from acts_as_paranoid filter down to an :include? For instance class parent acts_as_paranoid has_many: children end and class child acts_as_paranoid belongs_to :parent end Then if you Parent.find(:all, :include => children) you will get all the children if they are deleted or not. I guess the find that filters out the deleted_at is null does not filter down to the includes

So I have a model that acts_as_tree and I run a method on a collection of all of these records. This method walks the tree and fetches the parent/children, etc. This results in many, many duplicate SQL queries to be executed. Is there a way to eagerly load all of these models? Something along the lines of: Model.find(:all, :include => [:children, :parent]) If I execute the above statement, I

In DHH''s keynote, he alluded to doing logins with REST. Has anyone implemented this, and if so, would you mind elaborating on how you did it please? Thanks in advance. -- Posted via http://www.ruby-forum.com/.

I have a STI class tree. I want to set some default values (calculated values so I can''t set it in the database as defaults) on every created instance regardless of what subclass is actually instantiated. So I figured adding a after_create callback in the top class in the hierarchy should do the trick. It seems it doesn''t get called :( Code: class SuperClass <

Is it possible to stack :include''s in a situation like this: A has_many Bs B belongs_to A B has_many Cs C belongs_to B The result of the query looking something like...

I have two models, Stop and Station, they relate one station to many stops. Stop has_one :station Station belongs_to :stop So I can do @station.stops, but I cant do @stop.station, is this right? For example in the view I have: <% for @stop in @stops %> <tr> <td><%= @stop.station.name %></td> <td><%= @stop.time.hour.to_s + '':''

I''m using bundled_resource, login_engine, and a few other plugins. It appears Rails considers plugins in alphabetic order. Turns out that there is a particular order that will work and alphabetic ain''t it. The login engine must be loaded first. Bundled resource then includes ''application_helper'' and the application helper includes LoginEngine. If

Ok, I have read most of Agile Web Dev... so I had a question about beautifying URLs using routes.rb. I''m trying to architect a content management system in which a user can create template pages. This way, when a user creates a template page nested within, it displays it as though it''s displaying a folder structure, much like a directory tree (using acts_as_tree). I have a

Hi I''d like to know how to have ActiveResource generate a URL for the /teams/1/edit type of resource. I''ve got custom_methods.rb and have used Team.find(1).get(:edit) This generates http://localhost:xxxx/teams/1/edit.xml But all I get returned is a hash of the attributes (in this case of team 1), rather than an object of team 1. In other words the

I want to have a form to change a users password. I can''t figure out what the method in the controller should look like. I tried @user.save and @user.update_attributes, but can''t get it to work. My Form: ############################## <%= start_form_tag :action => "update_password", :id => @user.id %> <%= password_field ("user",

So, I sat down to use set_fixture_class, and it bombed on the first thing I tried: set_fixture_class :content_drafts => "Article::Draft" I made a quick patch, and I''d appreciate a quick run through your tests to make sure it doesn''t disturb anything: http://dev.rubyonrails.org/ticket/4095 As I was typing this, I realized that the string gives us no benefits.

This GemPlugin will gzip your HTTP responses from mongrel if the client says that it supports it (eg, most modern browsers).

Search doesn''t seem to be working, so forgive me if I''m covering old ground here, but I''m having a difficult time figuring out how to implement a "SUM()" function using Active record. Obviously, I could just create a query, but I''d rather make it part of my active record object. Basically I have an object called "Report <
