has_many :through join table conditions not applied on create
Reported by Ehren | February 1st, 2011 @ 07:44 PM
Rails 3.0.3
Given the following models
class User < ActiveRecord::Base
has_many :roles
has_many :owner_roles, :class_name => "Role", :conditions => {"roles.name" => "project_owner"}
has_many :projects, :through => :roles
has_many :owned_projects, :through => :owner_roles, :source => :project
end
class Role < ActiveRecord::Base
belongs_to :user
belongs_to :project
end
class Project < ActiveRecord::Base
has_many :roles
has_many :users, :through => :roles
end
When I attempt to use the owned_projects association to create a
project for a user:
User.first.owned_projects.create
I get the error
ActiveRecord::UnknownAttributeError: unknown attribute: roles.name
The expected behavior is that the name attribute on the role record used to join the user to the new project would be set to "project_owner"
