Question

rails 5.0.4 ruby 2.5.1 rspec 3.7 capybara

我需要一些有关创建工厂以及如何在功能说明中使用它们的帮助。我一直遇到同样的问题，当我认为解决了这个问题时，我又遇到了同样的问题。

型号：

customer.rb
 has many jobs

job.rb
 belongs to customer
 has_many hours

hour.rb
 belongs to job

工厂：

#customer.rb
FactoryGirl.define do
  factory :customer, :class => Customer do
    name "abc construction"
    contact "John"
    street "101 Main street"
    city "Anywhere"
    state "NY"
    zip "12345"
    phone "123-555-4567"
  end
end

#job.rb
FactoryGirl.define do
  factory :job, :class => Job do
    customer_id
    street "55 first str"   
    city "Anywhere"
    state "NY"
    zip "12345"  
    phone "123-456-7890"
    created_at Time.now
    updated_at Time.now
    description  "Test Job"
    name "house repairs"    
  end
end

# hour.rb
FactoryGirl.define do
  factory :hour, :class => Hour do
    job_id
    date_worked Date.today  
    hours 1
    description "test"   
  end
end

小时功能说明

# hours_spec.rb
context "edit form" do
    before(:each) do
      customer=FactoryGirl.create(:customer)
      job=FactoryGirl.create(:job, :customer_id => customer.id)
      hours=FactoryGirl.create(:hour, :job_id => job.id)

      visit edit_hour_path(:id => hours.id)
    end
    scenario "update messages shows" do
      within('form') do
        fill_in 'hour_description', with: 'testing'
      end
      click_button("Update Hours")
      expect(page).to have_content("You updated the record")
    end
  end

运行小时规格测试

rspec spec/features/hours_spec.rb
...
.....Capybara starting Puma...
* Version 3.9.1 , codename: Private Caller
* Min threads: 0, max threads: 4
* Listening on tcp://127.0.0.1:44465
.DEPRECATED: Capybara::Helpers::normalize_whitespace is deprecated, please update your driver
.F

Failures:

  1) Hours edit form update messages shows
     Failure/Error: job=FactoryGirl.create(:job, :customer_id => customer.id)

     ArgumentError:
       Trait not registered: customer_id
     # ./spec/features/hours_spec.rb:58:in `block (3 levels) in <top (required)>'

Finished in 0.86646 seconds (files took 1.24 seconds to load)
8 examples, 1 failure

如果将我的工作工厂更改为具有customer_id的值，则会收到类似的错误，但有一个数字（488）。也许它会显示为customer_id？

FactoryGirl.define do
  factory :job, :class => Job do
    customer_id FactoryGirl.create(:customer)
    ...
end

rspec spec/features/hours_spec.rb

Failures:

  1) Hours edit form update messages shows
     Failure/Error: job=FactoryGirl.create(:job, :customer_id => customer.id)

     ArgumentError:
       Trait not registered: 488
     # ./spec/features/hours_spec.rb:58:in `block (3 levels) in <top (required)>'

我在做什么错？正确的方法是什么？

感谢您的帮助！

Answer 1

您需要将哈希传递给工厂方法，而不是分配局部变量

job=FactoryGirl.create(:job, customer_id: customer.id)

尽管由于您在工作和客户之间建立了belongs_to关联，所以您应该在factory_girl（现在称为factory bot）中进行关联，并在工厂中拥有customer，而不是customer_id https://github.com/thoughtbot/factory_bot/blob/master/GETTING_STARTED.md#associations

Answer 2

FactoryGirl最近被重命名为FactoryBot，并且由于与日期有关的问题而取消了对为属性分配静态值的支持（工厂中的所有日期/时间将始终被指定为读取代码的时间/日期，而不是它实际上是在运行。您应该进行更新，并在工厂中使用关联，而不是直接分配ID。


#customer.rb
FactoryBot.define do
  factory :customer, :class => Customer do
    name { "abc construction" }
    contact { "John" }
    street { "101 Main street" }
    city { "Anywhere" }
    state { "NY" }
    zip { "12345" }
    phone { "123-555-4567" }
  end
end

#job.rb
FactoryBot.define do
  factory :job do # class defaults to one matching the factory name
    customer # association type defaults to one matching the name
    street { "55 first str" }   
    city { "Anywhere" }
    state { "NY" }
    zip { "12345" }  
    phone { "123-456-7890" }
    # created_at and updated_at are handled automatically 
    # created_at { Time.now }
    # updated_at { Time.now }
    description  { "Test Job" }
    name { "house repairs" }    
  end
end

job = FactoryBot.create（：job）＃这将自动创建一个关联的客户

job = FactoryBot.creatE（：job，客户：FactoryBot.create（：customer，名称：'abc'））＃将使用作为关联客户传递的客户
