php - CakePHP ACL 教程 initDB 函数警告

Question

我关注 http://book.cakephp.org/2.0/en/tutorials-and-examples/simple-acl-controlled-application/part-two.html教程和我的组略有不同(第 4 组和第 5 组)4 是访客，5 是管理员

    function initDB() {
 10         $group = $this->User->Group;
 11         //Allow admins to everything
 12         $group->id = 5;      
 13         $this->Acl->allow($group, 'controllers');
 14        //^doesnt work
 15        //$this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 5), 'controllers');
 16        
 17        
 18         $group->id = 4;
 19         $this->Acl->deny($group, 'controllers');
 20         $this->Acl->allow($group, 'controllers/User/login');
 21         $this->Acl->allow($group, 'controllers/User/logout');
 22        /*
 23        $this->Acl->deny(array( 'model' => 'Group', 'foreign_key' => 4), 'controllers');
 24        $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 4), 'controllers/User/login');
 25        $this->Acl->allow(array( 'model' => 'Group', 'foreign_key' => 4), 'controllers/User/logout');
 26 */      
 27         
 28         
 29         echo "all done";
 30         exit();
 31     }

但是当我运行此功能时，出现以下错误

Warning (512): DbAcl::allow() - Invalid node [CORE/Cake/Controller/Component/AclComponent.php, line 387]
Warning (512): DbAcl::allow() - Invalid node [CORE/Cake/Controller/Component/AclComponent.php, line 387]all done

是什么赋予了？!

编辑 - 我的 App Controller 看起来像这样

<?php

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() {
        $this->Auth->actionPath = 'controllers/';
        //Configure AuthComponent
        $this->Auth->loginAction = array('controller' => 'users', 'action' => 'login');
        $this->Auth->logoutRedirect = array('controller' => 'users', 'action' => 'login');
        $this->Auth->loginRedirect = array('controller' => 'images', 'action' => 'index');
        $this->Auth->allow('display');
    }   
}


?>

编辑2:
完整警告看起来像这样

如果您希望我发布任何其他代码，请告诉我。

根据警告，以及您调用 3 次的事实 $this->Acl->allow()一次$this->Acl->deny()但似乎只收到 2 个警告，我假设发出警告的行如下:

$this->Acl->allow($group, 'controllers/User/login');
$this->Acl->allow($group, 'controllers/User/logout');

我不使用 AclExtras 将 acos 表与现有操作同步，但 AFAIK 在检查 AclComponent 的权限时要求 acos 表中的 Controller 别名是复数形式。所以我假设您的 acos 表不包含任何别名为 User 的记录但是一条别名为 Users 的记录.

这可以解释为什么您的 acos 表中没有任何可以由 'controllers/User/login' 识别的节点。也不是 'controllers/User/logout' .

如果我的假设是正确的，那么以下代码将起作用:

$this->Acl->allow($group, 'controllers/Users/login');
$this->Acl->allow($group, 'controllers/Users/logout');
