Rails3國外主鍵錯誤圓形

Question

我在我的RoR3.2.1應用程序中通過關係直接轉發了has_many。唯一的變化是我正在使用一個不同的外鍵/主鍵，因爲我使用的是舊數據庫。

出於某種原因，當我創建新記錄時，這些值將保存在錯誤的字段中。組名保存到用戶名中，反之亦然。

我的radusers通過radusergroups有很多radgroups。我的連接表有列用戶名和組名。

Raduser.rb：

has_many :radusergroup, :dependent => :destroy, :foreign_key => :groupname, :primary_key => :username 
has_many :radgroup, :through => :radusergroup 

Radgroup.rb：

has_many :radusergroup, :dependent => :destroy 
has_many :raduser, :through => :radusergroup 

Radusergroup.rb

belongs_to :raduser, :primary_key => :username 
belongs_to :radgroup, :primary_key => :groupname, :foreign_key => :username 

我在表單中有這樣的：

- Radgroup.all.each do |radgroup| 
    = check_box_tag "raduser[radgroup_ids][]", radgroup.id, @raduser.radgroup.include?(radgroup), :id => "raduser_radgroup_id_#{radgroup.id}" 
    = radgroup.groupname 

當我打救，我的記錄保存周圍走錯了路：

INSERT INTO `radusergroup` (`groupname`, `id`, `priority`, `username`) VALUES ('username1233', NULL, 1, 'groupname123') 

而且表：

+------------------+--------------+----------+----+ 
| username   | groupname | priority | id | 
+------------------+--------------+----------+----+ 
| groupname123  | username1233 |  1 | 1 | 
+------------------+--------------+----------+----+ 

任何人在那裏能夠幫助呢？

我相信沒有：爲primary_key選項關聯。這必須在課堂上進行定義。你可以嘗試改變你的類此：

Raduser.rb：

primary_key :username 

has_many :radusergroup, :dependent => :destroy, :foreign_key => :username 
has_many :radgroup, :through => :radusergroup 

Radgroup.rb：

primary_key :groupname 

has_many :radusergroup, :dependent => :destroy, :foreign_key => :radgroup 
has_many :raduser, :through => :radusergroup 

Radusergroup.rb

belongs_to :raduser, :foreign_key => :username 
belongs_to :radgroup, :foreign_key => :groupname
