使用 Factory_Girl 设置嵌入式 Mongoid 模型

Question

所以我正在使用 Mongoid、Rspec 和 Factory_Girl，但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

所以当我这样定义工厂时：

FactoryGirl.define do
  factory :profile do
    #fields

    address
  end
end

我收到这样的错误：

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.

我通过将工厂更改为这样的方式使其工作：

FactoryGirl.define do
  factory :profile do
    #fields

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

这可行，但我希望有一种更原生的 Factory_Girl 方式来执行此操作。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 而不是create_address。在我看来，您的工厂已损坏，因为您试图在保留（创建）个人资料记录之前创建地址记录。 build_* 应该将所有必要的属性分配给父模型，然后它应该与它的嵌入关系一起被持久化。
