工厂女孩多个has_many通过的 [英] factory girl multiple has_many through's

问题描述

我需要创建一些工厂，这些工厂由多个具有很多贯通的工厂组成

I need to create some factories that are made of multiple has many through's

这是我的模特

Topic
  has_many :plan_topics
  has_many :plans, :through => :plan_topics

PlanTopic
  belongs_to :plan
  belongs_to :topic

Plan
  has_many :subscriptions
  has_many :members, :through => :subscriptions
  has_many :plan_topics
  has_many :topics, :through => :plan_topics

Subscription
  belongs_to :member
  belongs_to :plan

Member
  has_many :subscriptions
  has_many :plans, :through => :subscriptions

这就是我所拥有的

Factory.define :topic do |topic|
  topic.name "Operations"
end

Factory.define :plan do |plan|
  plan.title "A test Finance plan"
  plan.price "200"
end

Factory.define :plan_topic do |plan_topic|
  plan_topic.topic {|topic| topic.association(:topic)}
  plan_topic.plan {|plan| plan.association(:plan)}
end

我想做的是-Factory(:member_with_subscription)

What I would like to do is this - Factory(:member_with_subscription)

Factory.define :member_with_subscription do |subscription|
  subscription.association(:plan_with_topic)
  subscription.association(:member)
end

有没有办法做到这一点?

Is there a way of doing this ?

推荐答案

考虑使用after_build回调设置所有必需的依赖项.例如:

Consider using after_build callback to set all required dependencies. For example:

Factory.define :member_with_subscription, :class => 'Member' do |m|
  m.after_build do |member|
    member.subscriptions << Factory.build(:subscription)
  end
end
