Я получаю undefined method 'answers'
ошибку с этим: @survey.questions.answers
Просто запуск @survey.questions
работает, как вы ожидаете.
Вот мои настройки модели:
class Survey < ActiveRecord::Base
has_many :questions
accepts_nested_attributes_for :questions, :reject_if => lambda { |a| a[:text].blank? }, :allow_destroy => true
end
class Question < ActiveRecord::Base
belongs_to :survey
has_many :answers
accepts_nested_attributes_for :answers, :reject_if => lambda { |a| a[:text].blank? }, :allow_destroy => true
end
class Answer < ActiveRecord::Base
belongs_to :question
has_many :responses
end
Итак, что я здесь не так делаю?У каждой модели есть правильное поле _id
для создания ассоциации.
Я использую Rails 3.0.3.Кроме того, вот полный след:
>> @survey.questions.answers
