similar to: belongs_to not saving foreign key

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

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

Suppose I have a site about books and authors, and users can leave comments on either a book or an author. 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 encountered what seems like an odd omission in the behaviour of belongs_to associations: if you assign to the foreign key attribute, it doesn''t update the associated object (or mark a previously loaded one as stale) until you explicitly save or reload it. Let''s say we have a Company model, which belongs_to :city : >> torchbox =

Hi, Haven''t been able to find this raised before but I''m sure it must have been. When assigning an object to a belongs_to association I would like it to call the *association*_id= method instead of directly updating the attributes array. This is because I want to modify the behaviour when assigning a particular object without writing separate methods for whether it''s

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

Hello, I''m learning A.R Associations by creating a simple forum that consists of 3 tables: ahuthors, topics and posts. This is the schema: class AddAuthorAndTopicAndPostTables < ActiveRecord::Migration def self.up create_table :authors do |t| t.column :username, :string t.column :email, :string t.column :created_on, :datetime end create_table

Hello, Hope this isn''t a newbie question - but I don''t seem to be able to find relevent information elsewhere. I am having trouble getting the following to work: Schema ====== ActiveRecord::Schema.define(:version => 1) do create_table "authors", :force => true do |t| t.column "name", :string end create_table "books", :force =>

Perhaps this is intentional, but it seems unlikely: class Person < ActiveRecord::Base belongs_to :school end p = Person.find(:first) p.school # nil p.school_id = School.find_by_name(''High School'').id p.school.name # High School p.school_id = School.find_by_name(''Primary School'').id p.school.name # High School <= Shouldn''t this be Primary

Hi, In this tutorial http://wiki.rubyonrails.com/rails/show/HowtoUseJoinsWithFindAll it sad: sql =<<SQL SELECT articles.*, authors.name AS author_name FROM articles LEFT JOIN authors ON author_id = authors.id SQL and this return *app/controllers/media_controller.rb:366: can''t find string "SQL" anywhere before EOF* what is wrong? the tutorial or ruby changed? please,

Suppose I have three tables - authors, posts and topics. Every post have a topic and every topic has an author, so I have posts.topic_id and topic.author_id. When the author is guest (not registered), author_id is nil. I need to find all the posts (in one query) where every post have all the information of the topic and the auther, so if p is one of those posts I could get the name of the

Something is getting lost here. def create @home = Team.find_by_user_id(current_user.id) for player in @home.players player.update_attribute(:game_id, @game.id) end end def show @players = Player.find_all_by_game_id(params[:id]) end view <%= @players.size %> # mistakenly equals zero Played with the console and everything should be working fine...

Hi, Everything is in the title. With Rails 2.3.4 and MySQL 5.0.41: If have a table like this: +----------------+------------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+------------+------+-----+---------+----------------+ | id | int(11) | NO | PRI | NULL |

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 =>

Hi! I faced some issue while using it for dynamic attrs indexing/search. Maybe I made something wrong. Here is test method. Everything works just fine until last line http://pastie.caboo.se/66274 . Tested on both stable and trunk of aaf and ferret 0.11.4. the short version of code below: Contact.acts_as_ferret :fields => [ :first_name ] assert

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.

Hey, I got a form which looks like this: - form_for(@article, :html => {:multipart => true}, :url => articles_path) do |f| = errors_for(@article) .field = f.label :text %br = f.text_field :text .field = f.label :author_id %br = f.text_field :author_id .actions = f.submit But since I don''t want anyone to type in an author id I changed it

I''m trying to write a test like the one at the bottom of page 148 in Agile Rails. I''m using rails 1.0 I''ve created the fixture correctly I''m pretty sure because the test database table is being populated per the fixture. I have what I think is a simple unit test: ========= require File.dirname(__FILE__) + ''/../test_helper'' class CaseTest
