工厂女孩:如何建立has_many/through关联 [英] Factory Girl: How to set up a has_many/through association

问题描述

我一直在努力使用Factory Girl建立has_many/through关系.

I've been struggling with setting up a has_many/through relationship using Factory Girl.

我有以下型号:

class Job < ActiveRecord::Base
  has_many :job_details, :dependent => :destroy
  has_many :details, :through => :job_details
end

class Detail < ActiveRecord::Base
  has_many :job_details, :dependent => :destroy
  has_many :jobs, :through => :job_details
end

class JobDetail < ActiveRecord::Base
  attr_accessible :job_id, :detail_id
  belongs_to :job
  belongs_to :detail
end

我的工厂:

factory :job do
  association     :tenant
  title           { Faker::Company.catch_phrase }
  company         { Faker::Company.name }
  company_url     { Faker::Internet.domain_name }
  purchaser_email { Faker::Internet.email }
  description     { Faker::Lorem.paragraphs(3) }
  how_to_apply    { Faker::Lorem.sentence }
  location        "New York, NY"
end

factory :detail do
  association :detail_type <--another Factory not show here
  description "Full Time"
end

factory :job_detail do
  association :job
  association :detail
end

我想要的是在默认Detail为全职"的情况下创建我的工作工厂.

What I want is for my job factory to be created with a default Detail of "Full Time".

我一直在尝试遵循此方法，但是没有任何运气: FactoryGirl有很多通过

I've been trying to follow this, but have not had any luck: FactoryGirl Has Many through

我不确定应如何使用after_create通过JobDetail附加明细.

I'm not sure how the after_create should be used to attach the Detail via JobDetail.

推荐答案

尝试类似的方法.您要构建一个detail对象，并将其附加到作业的详细信息关联中.当您使用after_create时，创建的作业将被屈服于该块.因此，您可以使用FactoryGirl创建一个明细对象，并将其直接添加到该作业的明细中.

Try something like this. You want to build a detail object and append it to the job's detail association. When you use after_create, the created job will be yielded to the block. So you can use FactoryGirl to create a detail object, and add it to that job's details directly.

factory :job do
  ...

  after_create do |job|
    job.details << FactoryGirl.create(:detail)
  end
end
