Symfony2的：插入王牌

Question

类

我有这样的错误，当我尝试在类中添加王牌：

警告：PDO ::引用（）预计参数1是字符串，对象... /供应商指定/doctrine/dbal/lib/Doctrine/DBAL/Connection.php线568

我的代码：

$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？

尝试定义，像这样的对象标识：

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