Rspec 工厂女工通过协会有很多经验

我在这里遵循公认的答案

我有很多朋友通过协会

class Therapist < ActiveRecord::Base

has_many :clients, dependent: :destroy
has_many :courses, through: :clients

当我运行测试时，我得到以下错误

Failure/Error: let(:therapist) { create :therapist_with_course }
 ActiveRecord::HasManyThroughCantAssociateThroughHasOneOrManyReflection:
   Cannot modify association 'Therapist#courses' because the source reflection class 'Course' is associated to 'Client' via :has_many.

首先应该创建治疗师工厂，在创建治疗师之后，您将附加课程工厂。在你的案例中，你的工厂：治疗师和你的课程没有关于治疗师的信息

课程和客户端模型中的关联是如何定义的？类课程FactoryGirl.define do factory :course do client end end

Failure/Error: let(:therapist) { create :therapist_with_course }
 ActiveRecord::HasManyThroughCantAssociateThroughHasOneOrManyReflection:
   Cannot modify association 'Therapist#courses' because the source reflection class 'Course' is associated to 'Client' via :has_many.

FactoryGirl.define do
   factory :therapist do
      # The therapist attributes here
      after(:create) { |therapist| therapist.courses << FactoryGirl.create(:course) }
   end
end
