可以在控制器规范中创建记录吗？

Question

我写了下面的例子：

it "should assign @services containing all the current user services" do
  customer = FactoryGirl.create(:user, fullname: "Iris Steensma")
  sign_in customer
  service = FactoryGirl.create(:service, user: customer)
  puts "Service.count = #{Service.count}" # Service.count = 0
  get :home
  assigns[:services].should eq([service])
end

动作控制器为：

def home
 #@services = curent_user.posted_services
 @services = Service.all
end

且 factory.rb 包含：

FactoryGirl.define do

  sequence :address do |n|
    "Street #{n}"
  end

  factory :user do
    fullname "Foo Bar"
    email { "#{fullname.gsub(' ', '.').downcase}@example.com" if fullname }
    password "secret"
  end

  factory :preference do
    profile "customer"
    user
  end

  factory :service do
    status :pending
    source_addr { generate(:address) }
    target_addr { generate(:address) }
    passenger "Mis Daysi"
    start_at Time.now
    offer 5
    payment "cash"
    user
  end

end

为什么 Factory Girl 无法创建服务记录？工厂在“rails c test”测试环境下工作正常

这是 rspec 输出：

Failures:

  1) UsersController GET home should assign @services containing all the current user services
     Failure/Error: assigns[:services].should eq([service])

       expected: [#<Service:0x460d8ea @name="Service_1003">]
            got: []

       (compared using ==)

Answer 1

我相信正确的语法是：

assigns(:service).should eq([service])

根据 rspec 文档 assigns[key] 曾经是分配实例变量的方式，这看起来有点像你正在发生的事情。

首先，这里的 user: customer 不需要，因为您使用的 customer.services.create 已经这样做了

service = customer.services.create(attributes_for(:service, user: customer))

其次，试试这个，在 service = customer.services.create 之后做类似的事情

service.valid?
puts service.errors.inspect
puts service.user == customer

也许你也可以试试

service = FactoryGirl.create(:service, :user => customer)

另外，您确定关联是在服务类上定义的吗？

没有

#<Service:0x57856f4 @name="Service_1003">

应该是

#<Service:0x57856f4 @name="Service_1003" user="<your customer object">

?

您的服务工厂是如何定义的？
