Symfony2的：插入王牌

Question

類

我有這樣的錯誤，當我嘗試在類中添加王牌：

警告：PDO ::引用（）預計參數1是字符串，對象... /供應商指定/doctrine/dbal/lib/Doctrine/DBAL/Connection.php線568

我的代碼：

$oid = new ObjectIdentity('class', new Post()); 

$aclProvider = $this->get('security.acl.provider'); 

try { 
    $acl = $aclProvider->createAcl($oid); 
} catch (AclAlreadyExistsException $exists) { 
    return; 
} 

$builder = new MaskBuilder(); 
$builder->add('view'); 
$mask = $builder->get(); 

$acl->insertClassAce(new RoleSecurityIdentity('IS_AUTHENTICATED_ANONYMOUSLY'), $mask); 

$aclProvider->updateAcl($acl); 

任何想法？

嘗試定義，像這樣的對象標識：

$entityoid = new ObjectIdentity('class', 'YourComp\\YourBundleBundle\\Entity\\Post');
