设计 - 从两个模型登录 [英] Devise - login from two model

问题描述

我有两个用户的机型，首先是从远程数据库遗留和公司内部的目的。 （员工登录）。二是我们的公共登记项目，并登录。但我想要一个登录表单。我搜索了很长一段时间，但一些解决方法混淆了我。

i have two user models, first is from remote database as legacy and for internal company purposes. (Employee logins). Second is our project for public registration and sign in. But i want one login form. I have searching long time, but some solutions are confusing for me.

一是传统的样子（只用于读取和验证）：

First legacy looks like (only for reading and authentication):

class CrmUser < ActiveRecord::Base

  require Rails.root.join('lib', 'devise', 'encryptors', 'sha1')
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable, :rememberable, and :omniauthable
  establish_connection "crm_data"
  set_table_name :users

  devise :database_authenticatable, :encryptable, :authentication_keys => [:login]
  alias_attribute :encrypted_password, :crypted_password
  alias_attribute :password_salt, :salt

  # Setup accessible (or protected) attributes for your model
  attr_accessible :login, :password, :password_confirmation, :remember_me, :role_id, :first_name, :last_name

第二，公众和注册：

And second, for public and registration:

class User < ActiveRecord::Base

  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable, :rememberable, and :omniauthable
  devise :database_authenticatable, :registerable, :authentication_keys => [:login]
  alias_attribute :login, :email

  # Setup accessible (or protected) attributes for your model
  attr_accessible :login, :password, :password_confirmation, :remember_me, :role_id, :first_name, :last_name

但现在我不知道该怎么做用户控制器尝试验证从第一种模式，当用户不存在，请转到第二个模型，并再次尝试。

But now i don't know how to do that User controller try to authentication from first model, and when user doesn't exists, go to second model and try it again.

使用：

• 的Rails 3.1


• 设计1.4.3

编辑：

在设计的Wiki是一些关于多模型，但我有点混乱，没有例子更为复杂。

In wiki of Devise is something about multiple model, but i'm little bit confusing, there are not example more complex.

推荐答案

您应该猴补丁 find_for_authentication 从方法设计/模型/ authenticatable.rb

module Devise
  module Models
    module Authenticatable
      def find_for_authentication(conditions)
          #put your authentication logic here
        end
    end
  end
end

关于身份验证的逻辑：
使用两个模型针对你的情况验证它是真的坏主意。您是如何想建立与两个用户模式的关系？这是一个很多不必要的code的。

About authentication logic: Using two models for authentication in your case it's realy bad idea. How do u want build relations with two users models? It's a lot of unnecessary code.

解决你的问题的正确方法是使你的表之间存在一些同步。

Correct way of resolving your problem is make some synchronization between yours tables.

• 尝试进行身份验证与基本用户模式的用户。

• Try to authenticate user with base User model.

如果用户凭据是错误的 - 试图向他CrmUser模型验证

If user credentials was wrong - try to authenticate him with CrmUser model.

如果有CrmUser认证是确定的他添加到用户表如果他不存在，存在了。

If authentication with CrmUser was OK add him to users table if he doesn't exists there already.

返回用户的模型对象。
