Question

我在RoR3.2.1应用程序中有一个直接的has_many关系。唯一的变化是我正在使用不同的外键/主键，因为我正在使用旧数据库。

出于某种原因，当我创建新记录时，值会保存在错误的字段中。组名保存到用户名，反之亦然。

我的radusers通过radusergroups有很多radgroups。我的连接表包含用户名和组名列。

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

我的形式是：

- 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

当我点击保存时，我的记录保存错误：

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

表格：

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

那里的任何人都可以帮忙解决这个问题吗？

我认为没有：关联的primary_key选项。这必须在课堂上定义。您可以尝试将课程更改为：

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
