Rails FactoryGirl特征与模型after_create回调的关联未设置vanity_url

问题描述

在我的模型中，我有一个after_create回调来触发该方法:

class Job < ActiveRecord::Base
  after_create :update_vanity_url

  private

  def update_vanity_url
    self.vanity_url = '/jobs/' + company.slug + '/' + slug + '/' + id.to_s + '/'
  end
end

这将为我的工作设置一个自定义URL，但是，当我尝试在优惠券工厂中使用该URL时，该URL未保存.优惠券是在未分配工作的情况下创建的.仅当使用优惠券时，它才与一个作业配对.我称其为已执行:

FactoryGirl.define do
  factory :coupon do
    code { rand(25**25) }
    percent_discount { rand(100**1) }
    start_at { Time.now }
    end_at { 30.day.from_now }

    trait :executed do |c|
      association :job, factory: [:job, :purchased] 
      c.executed_at { Time.now }
    end
  end
end

理想情况下，我希望能够调用有效的FactoryGirl.create(:coupon, :executed)，但永远不会调用after_create....

下面的每个问题注释，我添加了我的路线部分和更新:

路线

  resources :jobs, only: [:new] do
    collection do
      post 'new', to: 'jobs#create'
    end
    get '/review', to: 'reviews#new'
    patch '/review', to: 'reviews#update'
    get '/payment', to: 'payments#new'
    patch '/payment', to: 'payments#update'
  end
  match '/jobs/:company_slug/:job_slug/:id', via: :get, to: 'jobs#show'

解决方案

我研究了几个小时，这就是我发现可以使用的方法.原来不是FactoryGirl，而是模型本身...我想...

  def update_vanity_url
    self.vanity_url = '/jobs/' + company.slug + '/' + slug + '/' + id.to_s + '/'
    save
  end

In my model, I have an after_create callback that triggers the method:

class Job < ActiveRecord::Base
  after_create :update_vanity_url

  private

  def update_vanity_url
    self.vanity_url = '/jobs/' + company.slug + '/' + slug + '/' + id.to_s + '/'
  end
end

This sets up a custom url for my jobs, however, when I try to use this in my coupon factory it is not being saved. The coupon is created without a job assigned. Only when the coupon is used is it paired with one job. I referred to that as executed:

FactoryGirl.define do
  factory :coupon do
    code { rand(25**25) }
    percent_discount { rand(100**1) }
    start_at { Time.now }
    end_at { 30.day.from_now }

    trait :executed do |c|
      association :job, factory: [:job, :purchased] 
      c.executed_at { Time.now }
    end
  end
end

Ideally, I would like to be able to call FactoryGirl.create(:coupon, :executed) which works but the after_create is never called... Thoughts?

Per issue comments below, I have added my routes section and updates:

Routes

  resources :jobs, only: [:new] do
    collection do
      post 'new', to: 'jobs#create'
    end
    get '/review', to: 'reviews#new'
    patch '/review', to: 'reviews#update'
    get '/payment', to: 'payments#new'
    patch '/payment', to: 'payments#update'
  end
  match '/jobs/:company_slug/:job_slug/:id', via: :get, to: 'jobs#show'

解决方案

I researched this for hours, and this is what I found to work. It turns out it was not FactoryGirl, rather the model itself... I think...

  def update_vanity_url
    self.vanity_url = '/jobs/' + company.slug + '/' + slug + '/' + id.to_s + '/'
    save
  end
