无法在twig中从多个代理实体打印出实体ID

我希望有人可以帮助我，也许这是一个错误或有解决方案..

我有一个与客户实体具有ManyToOne关系的作业实体。

class Job {
 /**
 * @ORM\ManyToOne(targetEntity="Client")
 */
protected $client;}

当我从控制器获取客户端时

$client = $job->getClient();
// I could get client id here in controller, but could not render in twig template
$clientId = $client->getId(); 
return $this->render('client' => $client);

并在模板中呈现

{{ client.id|default('0') }}

始终输出0，

但客户端实体的所有其他属性都可以正确输出。

{{ client.name }}   ----> this can print out properly, except {{ client.id }}

我使用Netbeans调试窗口，我看到这个客户端实体是一个代理实体，它的__isInitialized__值是0，如果我设置：

$real_client = $em->getRepository('AceCoreBundle:Client')->find(4);

这是真实的实体，可以在树枝中输出客户端ID。

即使我有一个__isInitialized__值为1的代理实体，它也可以在树枝中输出实体的id值。

不确定它有什么问题..

由于这个问题，每次我必须渲染'client_id'=＆gt; $ clientId分别为twig 

return $this->render(array('client_id' => $clientId, 'client' => $client));


{{ client_id|default('0') }}  // in twig

无论如何我可以将代理实体转换为真实实体吗？

My Client实体代码的一部分如下：

edit.html.twig 

<input type=hidden id="client-id" value="{{ client.id }}" name="client_id">

我尝试使用NetBeans来调试它，我发现当我更改app / cache / dev / classes.php时，关于4867行，在函数getAttribute中，我在下面添加了一些代码

// if I add this change to , it can print out id properly...
                    if ($item == 'id') {
                        return $object->getId();
                    }

之前：

 return $object->$item;

然后我可以在树枝上打印出id属性..

我最好的猜测是，这是由于学说延迟加载客户端实体。您应该尝试将控制器的doctrine调用切换到具有客户端连接查询的存储库方法（如果需要，请不要忘记使用paginator）。或者在您的实体上切换默认提取模式（我不记得确切的步骤）。

仍然是一个奇怪的错误，请发布您的客户实体代码以获得更好的帮助。
