cakephp：acl问题：无法在用户控制器中使用initdb函数填充aros_acos表

Question

当我尝试运行app / users / initdb时，我收到警告512并且我无法填充aros_acos表。有谁知道我做错了：

 Warning (512): DbAcl::allow() - Invalid node [CORE\cake\libs\controller\components\acl.php, line 361]Code | Context

以下是我的users_controller.php

 class UsersController extends appController{
       var $name = 'Users';

function beforeFilter(){
    parent::beforeFilter();
    $this->Auth->allow(array('*'));
}

function index() {
    $this->User->recursive = 0;
    $this->set('users', $this->paginate());
}

function login(){
}

function logout(){
}
      .........

      function initdb(){
//gets reference of Group model and modify its id to be able to specify the ARO we wanted, this is due to how AclBehavior works. AclBehavior does not set the alias field in the aros table so we must use an object reference or an array to reference the ARO we want.
    $group=& $this->User->Group; 
    //Allow admins to everything
    $group->id=7;
    $this->Acl->allow($group,'controllers');

    //allow managers to posts and widgets
    $group->id=8;
    $this->Acl->deny($group,'controllers');
    $this->Acl->allow($group,'controllers/Posts');
    $this->Acl->allow($group, 'controllers/Widgets');


    //allow users to only add and edit on posts and widgets
    $group->id=9;
    $this->Acl->deny($group,'controllers');
    $this->Acl->allow($group,'controllers/Posts/add');
    $this->Acl->allow($group,'controllers/Posts/edit');
    $this->Acl->allow($group,'controllers/Widgets/add');
    $this->Acl->allow($group,'controllers/Widgets/edit');

    //we add an exit to avoid an ugly "missing views" error message
    echo "all done";
    exit;
}

非常感谢任何帮助。感谢。
