工厂女孩多次has_many通过

我需要创建一些由多个工厂组成的工厂

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 – 工厂（：member_with_subscription）

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

有办法做到这一点吗？

Answer 1

考虑使用after_build回调来设置所有必需的依赖项。 例如：

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

Answer 2

我的做法略有不同，这种方式可能稍微容易理解：

 FactoryGirl.define do factory :member_with_description do after(:build) do |member| member.subscriptions << FactoryGirl.build(:subscription) end end end
