I have tried to add dynamic Zend_Acl assertions to my project following this article: http://www.amazium.com/blog/content-driven-access-control-with-zend-acl
After days of thinking I still can't put it to work properly. It throws an error: "Catchable fatal error: Argument 1 passed to Application_Model_User::populate() must be an array, object given, called in C:\Program Files\Zend\Apache2\htdocs\guardian\application\models\User.php on line 14 and defined in C:\Program Files\Zend\Apache2\htdocs\guardian\application\models\User.php on line 92".
Through debugging I found out the line in ClientController
$subsidiary->setAllowed($this->_acl->isAllowed($user, $subsidiary));
caused the problem. But I cannot get how to make it work. It seems that isAllowed creates an instance of User though I pass it there directly.
My code is the following:
class My_Controller_Helper_Acl extends Zend_Acl{
public function __construct(){
$this->add(new Zend_Acl_Resource('index'));
$this->add(new Zend_Acl_Resource('client'));
$this->add(new Zend_Acl_Resource('search'));
$this->add(new Zend_Acl_Resource('subsidiary'));
$this->add(new Zend_Acl_Resource('user'));
$this->add(new Zend_Acl_Resource('error'));
$this->add(new Zend_Acl_Resource('subs'));
$guest = My_Role::ROLE_GUEST;
$client = My_Role::ROLE_CLIENT;
$technician = My_Role::ROLE_TECHNICIAN;
$coordinator = My_Role::ROLE_COORDINATOR;
$admin = My_Role::ROLE_ADMIN;
$this->addRole(new Zend_Acl_Role($guest));
$this->addRole(new Zend_Acl_Role($client));
$this->addRole(new Zend_Acl_Role($technician), $client);
$this->addRole(new Zend_Acl_Role($coordinator), $technician);
$this->addRole(new Zend_Acl_Role($admin));
$this->allow($guest, array('user', 'error'));
$this->deny($guest, 'user', array('register', 'rights', 'delete'));
$this->allow($client);
$this->deny($client, 'client', 'new');
$this->deny($client, 'client', 'delete');
$this->deny($client, 'user', array('register', 'rights', 'delete'));
$this->allow($client, 'subs', null, new My_Controller_Helper_UserOwned());
$this->allow($coordinator, 'client', array('new', 'delete'));
$this->allow($admin);
}
}
class My_Controller_Helper_UserOwned implements Zend_Acl_Assert_Interface{

if (!$resource instanceof Application_Model_UserOwnedInterface){
throw new Exception('UserOwnedInterface not implemented');
}
$auth = Zend_Auth::getInstance();
if(!$auth->hasIdentity()){
return false;
}
$user = new Application_Model_User($auth->getIdentity());
return $resource->isOwnedByUser($user);
}
}

$subsidiary->setAllowed($this->_acl->isAllowed($user, $subsidiary));

$this->view->subsidiaries = $subsidiaries;

When I put debug on the $options param in User in populate function, I get the result (1) when the user is created in ClientController [user = $users->getByUsername($this->_username);], which is correct. On the line with isAllowed, I mentioned in the beginning, I get the result (2). But I don't get why the User object is even created on that line. I'm desperate. Would you know, where the mistake is?
Result (1):
object(Application_Model_User)#169 (6) {
["idUser":"Application_Model_User":private] => string(1) "6"
["username":"Application_Model_User":private] => string(6) "klient"
["password":"Application_Model_User":private] => string(64) "82a78c724f3242148990897a3b754e1f57442311fab5cde74c2a238d8c8858fc"

["role":"Application_Model_User":private] => string(1) "4"
["userSubsidiaries":"Application_Model_User":private] => array(1) {
[0] => string(1) "2"
}
}
