CakePHP项目中引入Auth & Acl 控制

class AppController extends Controller {  
    public $components = array(  
        'Acl',  
        'Auth' => array(  
            'authorize' => array(  
                'Actions' => array('actionPath' => 'controllers')  
            )  
        ),  
        'Session'  
    );  
    public $helpers = array('Html', 'Form', 'Session');  
  
    public function beforeFilter() {  
        //Configure AuthComponent  
        $this->Auth->loginAction = array(  
          'controller' => 'users',  
          'action' => 'login'  
        );  
        $this->Auth->logoutRedirect = array(  
          'controller' => 'users',  
          'action' => 'login'  
        );  
        $this->Auth->loginRedirect = array(  
          'controller' => 'posts',  
          'action' => 'add'  
        );  
    }  
}

class User extends AppModel {  
    public $belongsTo = array('Group');  
    public $actsAs = array('Acl' => array('type' => 'requester'));  
  
    public function parentNode() {  
        if (!$this->id && emptyempty($this->data)) {  
            return null;  
        }  
        if (isset($this->data['User']['group_id'])) {  
            $groupId = $this->data['User']['group_id'];  
        } else {  
            $groupId = $this->field('group_id');  
        }  
        if (!$groupId) {  
            return null;  
        }  
        return array('Group' => array('id' => $groupId));  
    }  
    public function bindNode($user) {  
        return array('model' => 'Group', 'foreign_key' => $user['User']['group_id']);  
    }  
 }

class Group extends AppModel {  
    public $actsAs = array('Acl' => array('type' => 'requester'));  
  
    public function parentNode() {  
        return null;  
    }  
}

//app/Config/boostrap.php  
// ...  
CakePlugin::load('AclExtras');  
  利用bash命令生成可用的acos数据
Bash代码  
./Console/cake AclExtras.AclExtras aco_sync
