model

     attr_accessable  :xrk_user_id,  :user_name, :status, :user_type,:encrypted_password, :password, :current_password

db/migrate :reate_table

    create_table :users, comment: "用户表" do |t|

      ## Recoverable

      ## Rememberable

      t.datetime :current_sign_in_at
      t.datetime :last_sign_in_at
      t.string   :current_sign_in_ip
      t.string   :last_sign_in_ip

      ## Lockable

在 new 一个 user 的时候 xrk_user_id 时有值，但是 save 的时候却被清空了。请问这个是什么问题啊？???,在线等啊....(数据库用的是 PG)
