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_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

我想做的是将用于访问成员的方法从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，并且 organization.organization_members 返回以前的文档，即使它没有定义 Church_members。

如何说服 Mongoid 使用之前嵌入的集合名称并通过新方法调用（Organization#members 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
