我很难弄清楚这个错误的确切含义:

    An error occurred in a `before(:suite)` hook.
    Failure/Error: FactoryGirl.lint

    FactoryGirl::InvalidFactoryError:
      The following factories are invalid:

      * question - Validation failed: Option must 
      exist, Question must exist (ActiveRecord::RecordInvalid)  

这些是工厂:

    # question has many options through quiz
    FactoryGirl.define do
     factory :question, class: 'Question' do
       option "What color are your eyes"
     end
   end 

    # option has many questions through quiz
    FactoryGirl.define do
      factory :option, class: 'Option' do
        option "blue"
      end
    end

    # JoinTable 
    FactoryGirl.define do
      factory :quiz, class: 'Quiz' do
        option nil
        question nil
      end
    end

我的猜测是 nil 测验工厂中的关联旁边与错误有关。我试图阅读FactoryGirl的文档,以了解如何创建正确的关联,但我不理解某些事情。例如:

• 更重要的是,因为我想先创建一个问题,然后告诉问题它有什么选项,我如何在工厂中实现这一点?

编辑:

选项模型:

    class Option < ApplicationRecord
      has_many :quizzes
      has_many :questions, through: :quizzes
    end  

问题模型

   class Question < ApplicationRecord
     has_many :quizzes
     has_many :options, through: :quizzes
   end 

测验模型

    class Some::QuizQuestion < ApplicationRecord
      belongs_to :questions
      belongs_to :options
    end
