Question

使用Rails 3.2和Mongoid 2.4。我有一个遗留模型，即组织，embeds_many organization_members。它看起来像这样：

class Organization
  include Mongoid::Document

  embeds_many :organization_members
end

class OrganizationMembers
  include Mongoid::Document
  embedded_in :organization
end

我想要做的是将用于访问成员的方法从 organization.organization_members 更改为 organization.members 。这就是我所做的：

class Organization
  include Mongoid::Document

  embeds_many :members, class_name:"OrganizationMember"
end

class OrganizationMembers
  include Mongoid::Document
  embedded_in :organization
end

但是，现在organization.members返回一个空数组，organization.organization_members返回以前的文档，即使它没有定义church_members。

如何说服Mongoid使用以前的嵌入式集合名称并通过新的方法调用（Organization＃members not Organization＃organization_members）访问它？

Answer 1

embeds_many有一个选项，名为store_as。

class Organization
  include Mongoid::Document

  embeds_many :members, 
              class_name:"OrganizationMember", 
              store_as: 'organization_members'
end

更改mongoid embeds_many关联名称
