ruby-on-rails - 更改 mongoid embeds_many 关联名称

Question

使用 Rails 3.2 和 Mongoid 2.4。我有一个遗留模型 Organization，它嵌入了很多 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

我想做的是将我用来访问成员的方法从 organization.organization_members 更改为仅 organization.members。这是我所做的:

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，而 organization.organization_members 返回以前的文档，即使它没有定义 church_members。

我如何说服 Mongoid 使用以前的嵌入式集合名称并通过新方法调用(Organization#members 而不是 Organization#organization_members)访问它？

Answer 1

有一个选项 embeds_many ，称为 store_as。

class Organization
  include Mongoid::Document

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