I cant seem to use :through to get the grandchildren objects when the intermedetiate uses a has_one relationship with the grandchild model.
E.g. class User < ActiveRecord::Base has_many :sentences has_many :corrections, :through => :sentences end class Sentence < ActiveRecord::Base belongs_to :user has_one :correction end class Correction < ActiveRecord::Base belongs_to :sentence end I want to do User.corrections but unfortunately that doesnt work. I get ActiveRecord::HasManyThroughSourceAssociationMacroError: Invalid source reflection macro :has_one for has_many :corrections, :through => :sentences. Use :source to specify the source reflection. but if i remove the has_one and replace it with has_many like so class Sentence < ActiveRecord::Base belongs_to :user has_many :corrections #previously has_one end then It works. The problem is I dont want to specify has_many because there will only be one correction for a sentence. How do i achieve what I want, namely to be able to access all the corrections for a given user -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
