similar to: Call AR belongs_to association accessor ID method on object assignment

Hi, Does anyone know a good way to override AR associations to take special cases into account. My current take is the example below which allows the ''root'' user to access all products, but only works if I remember to call it with a .all/.find or similar method: ''user.products.all'' instead of ''user.products''. Ideally I guess I want to return a

Hi. I have a problem with the association methods which passed to a model through a belongs_to declaration. Here''s an illustration of the issue: GIVEN: # migration class CreateArticlesAndAuthorsTables < ActiveRecord::Migration   def self.up     create_table :articles do |t|       t.text     :title       t.integer :author_id     end     create_table :authors do |t|       t.text

Under Rails 2.3.2 using a completely brand new project, I have 2 models: class Author < ActiveRecord::Base # name:string end class Book < ActiveRecord::Base # title:string belongs_to :author # author_id end And a simple test where i create a Book with an Author using the belongs_to and then update the foreign key directly: require ''test_helper'' class BookTest

Seemingly, when I use a symbol, I get an ActiveRecord error stating ''Can''t convert symbol into String.'' Why can''t I use a symbol here? Possibly this is a deeper misunderstanding of symbols in general on my part. #ActiveRecord error class Book < ActiveRecord::Base belongs_to :author, :class_name => :Person, :foreign_key => :author_id end #works

I''d want to have a table called "comments", which could belong to either an author OR a book. In my structure I wouldn''t be sure whether to include an "author_id" or a "book_id", or both. What would be the best way to handle this

I''ve got a publications table that contains an author_id foreign key and a pubrole_id foreign key. What I want to do is query the DB using AR so that I can get a list of all publications that belong_to a particular author, and group the results by the pubrole.role_name (Author, Joint Author, Editor, etc.) so that the results look something like: Author book1 info book2 info etc.

Hello, I''m learning A.R Associations by creating a simple forum that consists of 3 tables: ahuthors, topics and posts.

Regarding validates_associated... Let''s say I have: article belongs_to author But for whatever reason, I want an article to also be written anonymously and therefore not require an author. Then I have: Article: belongs_to :author validates_associated :author But I DON''T have validates_presence_of. What I want to do is validate that an author is valid --if it is

Today I face with incorrect behavior in ActiveRecord. It take place when I try to use :include parameter for .find method. Where are two typical cases: 1. You have record with self-referential joins CREATE TABLE keywords (id, group_id); class Keyword < ActiveRecord::Base belongs_to :group, :class_name => "Keyword", :foreign_key =>
