I tried to user delete_if on an association: class Group < ActiveRecord::Base has_many :memberships, :dependent => :destroy has_many :users, :through => :memberships ... end This is the controller method, trying to use delete_if. Although some elements are removed (s2 < s1), the save method does not update the association. def intersect_or_remove_group other_group =

I am using elasticsearch for querying in my application. Lets say there are 2 models Class Topic has_many :posts and Class Article has_many :comments I want to do a combined search on both these models and my query looks like: Tire.search [Article, Topic], {:load => {:include => [:posts, :comments]}} do |search| ... end This is where I encounter a problem. I get the Association

If I try: articletmp.article_groups.each{ |x| @article.article_groups.delete(y) } It deletes some of the groups. @article.article_groups.clear works. Why dosn''t the to first examples work as expected?? Do I have to put groups I don''t want to

How can I get a list of all model classes in the domain of a Rails application (all models, both in "app/models" and in components/somedir/model.rb)? Thanx in advance for your precious help! Edoardo "Dado" Marcora

Hi Everyone, Do I edit the corresponding migration also to show the belongs_to (and the has_many)? I have a many to many relationship where I am using the "has_many :through" association. When I place in the individual classes the ''has_many :through'' and the ''belongs_to'' associations, do I also edit the corresponding migrations to reflect those

I am saving an array of active record objects (college courses) in the session as session[:course_list]. This is the cart for a registration controller. If a student chooses to delete the course from the list I get the :id as params[:id]. However if I do session[:course_list].delete_if {|x| x.id ==params[:id]} does not work. session[:course_list].delete_at(idx) works. Ocourse to do this I have

Hi all, In my controller I am doing the following to populate a nested form for a has_many through association: def new @specification = Specification.new Component.find_each.each do |component| @specification.component_specifications.build(:component_id => component.id) end The idea being whenever someone creates or edits a form, it will be populated with all

I have two model classes: class Item < ActiveRecord::Base belongs_to :channel, :counter_cache => true validates_presence_of :channel end class Channel < ActiveRecord::Base has_many :items, :dependent => true end In the Channel controller I have variable channel.items, an Array of Items. I would like to use the Array find method. However, channel.items.find() is a Rails

Considering an object with several has_many :through => associations, what is the ''best'' way to handle validations? As an example: class Student < ActiveRecord::Base # some attrbutes like # :name # :grade # relationships has_many :students_assignment, :dependent => :destroy has_many :assignments, :through => :students_assignment has_many

Hi all. Got a stupid-simple question about associations. I have two models - school and course. There are a fixed number of schools (set up in the migration). Each course is assigned a school and a school will be associated with multiple courses... How do I set up the associations? Do (can) I have School :has_one :course and Course :has_many :schools? Does the schools table then get a course_id

Hi. I have a couple of best practices questions regarding polymorphic associations, naming join tables and user permissions. Currently I have implemented the user authentication model from the rails recipes book. Basically it goes something like this: MODEL CLASSES: class User < ActiveRecord::Base has_and_belongs_to_many :roles end class Role < ActiveRecord::Base

Hi, I haven''t done any associations before, so please forgive my incorrect use of terminology... If I set up a has_many :through association, can I manipulate the associated instances directly (like an Array), or do I need to manipulate the join model? For example, suppose I have two classes and the associated join model: class foo has_many :foo_bars has_many :bars, :through

I posted something about this a week ago wihtout response, but have made some progress since. However, I''m still not getting exactly what I want. OK, three core tables: create_table :reference_items do |t| t.column :title, :string, :limit => 255 t.column :year, :integer, :limit => 4 t.column :type, :string t.column

Can someone clarify this for me? Suppose I have two tables like: class Company < ActiveRecord::Base belongs_to :category end class Category < ActiveRecord::Base has_many :companies end I understand that the belongs_to causes related companies to be read from the db when I ask for a category. I suspect SQL something like select * from categories, companies where category.id

Hi, here is a warningmessage i got while i am testing my new puppet installation with .23.2 and storedconfig and reports and all the bell and whistle :) DEPRECATION WARNING: Calling .create on a has_many association without saving its owner will not work in rails 2.0, you probably want .build instead See http://www.rubyonrails.org/deprecation for details.

Hi, I''m very new to rspec, so if this is not the right forum please let me know. I''m starting to spec my models first in an existing rails app, porting from a mix of Test::Unit, and simply_bdd amongst others. I''m at the point where I want to test that certain associations are present. What I''m not sure of is should I test the association or the method and

I have Users who can "own" Projects. There is only one owner. Users in general can be authorized to view certain projects. Here is my initial stab at this: class User < ActiveRecord::Base has_many :projects # ownership has_many :project_viewers, :dependent => :destroy has_many :projects, :through => :project_viewers, :uniq => true ... end class
