Cakephp 使用不同的表和列进行身份验证

如何在cakephp中更改用于身份验证的用户表名和列名。默认情况下，它以用户作为表名

class AppController extends Controller {

    public $components = array(
        'Session','Security',
        'Auth' => array(
            'loginRedirect' => array('controller' => 'project', 'action' => 'index', 'Project Details'),
            'logoutRedirect' => array('controller' => 'users', 'action' => 'login')
        )
    );



    function beforeFilter() {
        $this->Auth->allow('login');

    }
}

型号：

  App::uses('AppModel', 'Model');
    class Users extends AppModel {
    var $useTable = 'manager';


    }

在AppController的beforeFilter（）方法中添加以下代码

function beforeFilter(){
   parent::beforeFilter();
   $this->Auth->authenticate = array(
   AuthComponent::ALL => array("fields" => array("username" => "your_username_column", "password" => "your_password_column") )

))；

}

如何登录用户id和用户名$this->Auth->user（'id'）$此->身份验证->用户（'username'）；
