Question

所以我正在玩Mongoid，Rspec和Factory_Girl，我在嵌入式文档方面遇到了一些问题。

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

所以当我定义这样的工厂时：

FactoryGirl.define do
  factory :profile do
    #fields

    address
  end
end

我收到了这样的错误：

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.

我通过将工厂改为这样的方式来实现它：

FactoryGirl.define do
  factory :profile do
    #fields

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

这有效，但我希望有一种更原生的Factory_Girl方式。好像应该有。

提前致谢！

Answer 1

您也可以这样做，如Factory Girl + Mongoid embedded documents in fixtures中所述：

FactoryGirl.define do
  factory :profile do |f|
    #fields
    address { FactoryGirl.build(:address) }
  end
end

Answer 2

尝试使用build_address代替create_address。在我看来，你的工厂已经坏了，因为在创建配置文件记录之前，你正试图创建一个地址记录。 build_*应该为父模型分配所有必要的属性，以后它应该与其嵌入的关系一起保存。

使用Factory_Girl设置嵌入式Mongoid模型
