[PHP]Zend Framework zend_acl zend_auth Opcje

[cykcykacz]

Witam, uczę się Zend Framework z tutoriala, w pewnym momencie napotykam na błąd.

Plik Bootstrap.php

Kod

<?php

class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
    protected function _initAutoLoad() {

        $modelLoader = new Zend_Application_Module_AutoLoader(array(
                        'namespace' => '',
                        'basePath' => APPLICATION_PATH ));

        $this->_acl = new Model_LibraryAcl;
        $this->_auth = Zend_Auth::getInstance();

        $fc = Zend_Controller_Front::getInstance();
        $fc->registerPlugin(new Plugin_AccessCheck());

        return $modelLoader;
    }

Plik AccessCheck.php

Kod

<?php
class Plugin_AccessCheck extends Zend_Controller_Plugin_Abstract {

     private $_acl = null;
     private $_auth = null;

    public function __construct(Zend_Acl $acl, Zend_Auth $auth) {
        $this->_acl = $acl;
        $this->_acl = $auth;
    }
    public function preDispatch(Zend_Controller_Request_Abstract $request) {
                $resource = $request->getControllerName();
                $action = $request->getActionName();

                $identity = $this->_auth->getSorage()->read();
                $role = $identity->role;

                if(!$this->_acl->isAllowed($role, $resource, $action)){
                                $request->setControllerName('authentication')
                                        ->setActionName('login');
        }
    }
}

Plik LibraryAcl.php

Kod

<?php
class Model_LibraryAcl extends Zend_Acl {
    public function __construct() {
        $this->add(new Zend_Acl_Resource('sala'));
        $this->add(new Zend_Acl_Resource('edit'), 'sala');
        $this->add(new Zend_Acl_Resource('add'), 'sala');

        $this->add(new Zend_Acl_Resource('sale'));
        $this->add(new Zend_Acl_Resource('list'), 'sale');

        $this->addRole(new Zend_Acl_Role('user'));
        $this->addRole(new Zend_Acl_Role('admin'), 'user');

        $this->allow('user', 'sale', 'list');
        $this->allow('admin', 'sala', 'edit');
        $this->allow('admin', 'sala', 'add');
    }
}

Otrzymuję taki komunikat:

Kod

Catchable fatal error: Argument 1 passed to Plugin_AccessCheck::__construct() must be an instance of Zend_Acl, none given, called in C:\xampp\htdocs\sala\application\Bootstrap.php on line 15 and defined in C:\xampp\htdocs\sala\application\plugins\AccessCheck.php on line 7

Proszę o lekarstow:).
Ps: Pewnie wszystko jest ładnie opisane w komunikacie błędu, jednak ja jeszcze tego nie ogarniam.
