导轨定制foreign_key两个表上的名字

问题描述

我有两个型号，例如用户和俱乐部以及它们的属性：

I have two models, for example User and Club with their attributes:

User:
  id
  uid
  email
  etc.

和

Club:
  id
  player_id
  address
  supporter
  etc.

由于某些原因，连接属性是 clubs.player_id 与 users.uid 不是 clubs.player_id 与 users.id 。是否有可能连接这两个模型一到一使用联想 HAS_ONE 和 belongs_to的？ THX

For some reason, the join attribute is clubs.player_id with users.uid NOT clubs.player_id with users.id. Is it possible connecting these two model with one-to-one association using has_one and belongs_to? thx

推荐答案

我敢打赌，这将工作：

class User < ActiveRecord::Base
  has_one :club, :foreign_key => :player_id, :primary_key => :uid
end

class Club < ActiveRecord::Base
  belongs_to :user, :foreign_key => :player_id, :primary_key => :uid
end
