Given the following associations, I need to reference the Question
that a Choice
is attached through from the Choice
model. I have been attempting to use belongs_to :question, through: :answer
to perform this action.
class User
has_many :questions
has_many :choices
end
class Question
belongs_to :user
has_many :answers
has_one :choice, :through => :answer
end
class Answer
belongs_to :question
end
class Choice
belongs_to :user
belongs_to :answer
belongs_to :question, :through => :answer
validates_uniqueness_of :answer_id, :scope => [ :question_id, :user_id ]
end
I am getting
NameError uninitialized constant
User::Choice
when I try to do current_user.choices
It works fine, if I don't include the
belongs_to :question, :through => :answer
But I want to use that because I want to be able to do the validates_uniqueness_of
I am probably overlooking something simple. Any help would be appreciated.
You can also delegate:
class Company < ActiveRecord::Base
has_many :employees
has_many :dogs, :through => :employees
end
class Employee < ActiveRescord::Base
belongs_to :company
has_many :dogs
end
class Dog < ActiveRecord::Base
belongs_to :employee
delegate :company, :to => :employee, :allow_nil => true
end
