Example: class User < ActiveRecord::Base # I reference an account. You can add an object to a collection without automatically saving it by using the #collection.build method (documented below). I suspect that you originally got lucky: your include clause is [[:forfait => :vehicule] => :client] which ruby parses as [{[{:forfait=>:vehicule}]=>:client}] which isn''t the type of structure that rails is expecting Why does Deep Space Nine spin?

I'd try running it on that combo and see if there are still issues. Should any of the before_add callbacks throw an exception, the object does not get added to the collection. has_one :user end The tables for these classes could look something like: CREATE TABLE users ( id int(11) NOT NULL auto_increment, account_id int(11) default NULL, name varchar default NULL, PRIMARY KEY The error occurred while evaluating nil.update_attribute /home/manuel/scrum/teamtrick/spec/support/macros/controller_macros.rb:61:in `it_should_success_for_users_with_role' 5) NoMethodError in 'CommitmentsController responding to POST create should success for users with role scrum_master' You have a nil object when you didn't

Namespace children JoinDependency = private = protected Associations are a set of macro-like class methods for tying objects together through foreign keys. Association Join Models Has Many associations can be configured with the :through option to use an explicit join model to retrieve the data. If a table is referenced only once, the standard table name is used. You might have expected an instance of ActiveRecord::Base.

Why is the bridge on smaller spacecraft at the front but not in bigger vessels? check my blog Both express a 1-1 relationship, the difference is mostly where to place the foreign key, which goes on the table for the class saying belongs_to. Example: class Post < ActiveRecord::Base belongs_to :author has_many :comments end Consider the following loop using the class above: for post in Post.find(:all) puts "Post: " + post.title puts "Written by: " I want the loop to be able to spit out the cid/names as in id name 4 brick 9 tile 45 grout Right now I am getting The error occurred while
