Mongoid協會擴展代理所有者

Question

我正在努力如何去Mongoid的擴展協會所有者。 AFAIK它是ActiveRecords中的proxy_association.owner。

class Something 
    field :some_field 

    has_many :whatevers, extend: ExtraStuff 
end 

module ExtraStuff 
    def recent 
    # I need "some_field" here, but there's no "proxy_association" 
    end 
end 

Answer 1

我相信'基地'是你正在尋找的方法！

class Something 
    field :some_field 

    has_many :whatevers, do 
     def my_extension_method 
     klass # Something 
     base # #<Something _id="..." > 
     end 
    end 
end
