Having problems combining Zend_Acl and Zend_Navigation - zend-framework

Question

I have a Federico_Plugin_Acl that extends Zend_Controller_Plugin_Abstract which looks like this:
class Federico_Plugin_Acl extends Zend_Controller_Plugin_Abstract {
private $_acl = null;
private $_auth = null;
const DEFAULT_ROLE = 'guest';
public function __construct($auth) {
$this->_auth = $auth;
$this->_acl = new Zend_Acl();
$this->_acl->addRole(new Zend_Acl_Role(self::DEFAULT_ROLE));
$this->_acl->addRole(new Zend_Acl_Role('user'), self::DEFAULT_ROLE);
$this->_acl->addRole(new Zend_Acl_Role('admin'), 'user');
$this->_acl->addResource(new Zend_Acl_Resource('index'));
$this->_acl->addResource(new Zend_Acl_Resource('users'));
$this->_acl->addResource(new Zend_Acl_Resource('about'));
$this->_acl->addResource(new Zend_Acl_Resource('gisele'));
$this->_acl->addResource(new Zend_Acl_Resource('admin'));
$this->_acl->allow('guest', 'index');
$this->_acl->allow('guest', 'about');
$this->_acl->deny('guest', 'gisele');
$this->_acl->deny('guest', 'users');
$this->_acl->allow('user', 'users', array('index'));
$this->_acl->allow('admin', 'users');
$this->_acl->allow('admin', 'gisele');
}
public function preDispatch(Zend_Controller_Request_Abstract $request) {
if ($this->_auth->hasIdentity()) {
$role = $this->_auth->getStorage()->read()->role;
} else {
$role = self::DEFAULT_ROLE;
}
$action = $request->getActionName();
$controller = $request->getControllerName();
if ($this->_acl->has($controller)) {
if (!$this->_acl->isAllowed($role, $controller, $action)) {
$request->setActionName('login');
$request->setControllerName('index');
}
}
}
}
And this method is in my bootstrap to make use of this class:
protected function _initNavigation()
{
$this->_auth = Zend_Auth::getInstance();
$this->_acl = new Federico_Plugin_Acl($this->_auth);
$this->bootstrap('view');
$view = $this->getResource('view');
$config = new Zend_Config_Xml(APPLICATION_PATH . '/configs/navigation.xml','nav');
$navigation = new Zend_Navigation($config);
$roleAuth = $this->_auth->getIdentity();
if(null == $roleAuth)
$role = 'guest';
else
$role = $roleAuth->role;
$view->navigation($navigation)->setAcl($this->_acl)->setRole($role);
}
With these configurations set like that, I get the following error:
Catchable fatal error: Argument 1 passed to Zend_View_Helper_Navigation_HelperAbstract::setAcl() must be an instance of Zend_Acl, instance of Federico_Plugin_Acl given, called in /home/fiodorovich/public_html/gisele/application/Bootstrap.php on line 118 and defined in /home/fiodorovich/library/ZendFramework/library/Zend/View/Helper/Navigation/HelperAbstract.php on line 333
Call Stack
Which is to be expected since Federico_Plugin_Acl is an instance of Zend_Controller_Plugin_Abstract...Still, if I extend Zend_Acl instead I get this error:
Fatal error: Zend_Acl_Role_Registry_Exception: Role 'guest' not found in /home/fiodorovich/library/ZendFramework/library/Zend/View/Helper/Navigation/HelperAbstract.php on line 522
So...I've been trying for a while to get this thing solved,... but don't seem to get this to work properly...Any ideas on what I'm missing here?

Answer 1

Zend_Controller_Plugin_Abstract and Zend_Acl are completelly different things. What you want to do is get the ACL object out of your plugin (which is now in private section) and pass it over to
$view->navigation($navigation)->setAcl(<here>);
