更改mongoid embeds_many協會名稱

Question

使用Rails 3.2和Mongoid 2.4。我有一個遺留模型組織，即embeds_many organization_members。它看起來是這樣的：

class Organization 
    include Mongoid::Document 

    embeds_many :organization_members 
end 

class OrganizationMembers 
    include Mongoid::Document 
    embedded_in :organization 
end 

我希望做的是從organization.organization_members只是organization.members改變我用它來訪問成員的方法。下面是我做了什麼：

class Organization 
    include Mongoid::Document 

    embeds_many :members, class_name:"OrganizationMember" 
end 

class OrganizationMembers 
    include Mongoid::Document 
    embedded_in :organization 
end 

不過，現在organization.members返回一個空數組和organization.organization_members返回以前的文件，即使它church_members沒有定義。

如何說服Mongoid使用先前的嵌入式集合名稱並通過新的方法調用訪問它（組織成員不是Organization＃organization_members）？

Answer 1

有一個選項embeds_many，稱爲store_as。

class Organization 
    include Mongoid::Document 

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