Ruby on rails 3 用Factory_Girl建立嵌入式Mongoid模型

所以我在玩Mongoid、Rspec和Factory_Girl，我在嵌入文档时遇到了一些问题

我有以下型号：

class Profile    
   include Mongoid::Document

   #Fields and stuff
      embeds_one :address

   validates :address, presence: true 
end

class Address    
   include Mongoid::Document

   #Fields and stuff
      embedded_in :profile 
end

所以当我定义这样一个工厂时：

FactoryGirl.define do
  factory :profile do
    #fields

    address
  end
end

Failure/Error: subject { build :profile }
     Mongoid::Errors::NoParent:

       Problem:
         Cannot persist embedded document Address without a parent document.
       Summary:
         If the document is embedded, in order to be persisted it must always have a reference to it's parent document. This is most likely cause by either calling Address.create or Address.create! without setting the parent document as an attribute.
       Resolution:
         Ensure that you've set the parent relation if instantiating the embedded document direcly, or always create new embedded documents via the parent relation.

FactoryGirl.define do
  factory :profile do
    #fields

    after(:build) do |p| 
      p.create_address(FactoryGirl.attributes_for(:address))
    end
  end
end

我犯了这样一个错误：

FactoryGirl.define do
  factory :profile do
    #fields

    address
  end
end

Failure/Error: subject { build :profile }
     Mongoid::Errors::NoParent:

       Problem:
         Cannot persist embedded document Address without a parent document.
       Summary:

FactoryGirl.define do
  factory :profile do
    #fields

    after(:build) do |p| 
      p.create_address(FactoryGirl.attributes_for(:address))
    end
  end
end

我通过将工厂改成这样的方式来实现这一目标：

FactoryGirl.define do
  factory :profile do
    #fields

    address
  end
end

Failure/Error: subject { build :profile }
     Mongoid::Errors::NoParent:

       Problem:

  factory :profile do
    #fields

    after(:build) do |p| 
      p.create_address(FactoryGirl.attributes_for(:address))
    end
  end
end

这是可行的，但我希望有一个更本土的工厂女孩的方式来做这件事。看来应该有

提前谢谢

尝试使用

build\u address

而不是

create\u address

。在我看来，您的工厂被破坏了，因为您试图在配置文件记录被持久化（创建）之前创建一个地址记录<代码>构建*应将所有必要的属性分配给父模型，之后应将其与其嵌入的关系一起保存。

您也可以这样做，如中所述：

很公平，但是FactoryGirl中没有回调就无法处理这个问题吗？我不这么认为，这是mongodb/mongoid特定的东西。这在FactoryGirl 4.4.0中有效，但在4.5.0中似乎不再有效。请参阅我的（迄今尚未回答的）问题：
