無法在樹枝從許多打印出實體ID到一個代理實體

Question

我希望有人能幫助我，也許這是一個bug或者有它的解決方案..

我有具有多對一關係的作業實體到客戶實體。

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

當我從控制器

$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); 

獲得客戶，並使其在模板

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

它總是輸出0，

，但客戶端實體的所有其他屬性可以輸出正常。

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

，我使用NetBeans調試窗口，我看到這個客戶的實體是一個代理的實體，它的__isInitialized__值是0，如果我設置：

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

這是真正的實體，可以輸出客戶端id在樹枝。

即使我有一個__isInitialized__值爲1的代理實體，它也可以輸出實體的ID值在樹枝中。

不知道是什麼毛病吧..

由於這個問題，每次我都渲染時間‘的client_id’=> $單獨的clientId到小枝

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


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

反正是有我可以將代理實體轉換爲真實體？

      'client' => $client, 
     ); 
     } 

edit.html.twig

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

我試圖使用NetBeans調試它，我發現，當我更改應用程序/緩存的/ dev/classes.php，約行4867，在功能上的getAttribute，我前下方添加

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

一些代碼：

return $object->$item; 

然後，我可以在樹枝打印出id屬性..

Answer 1

我最好的猜測是，這是由於教義延遲加載客戶端實體。你應該試着將控制器的原則調用切換到一個存儲庫方法，並在客戶端加入查詢（如果需要，不要忘記使用paginator）。或者在您的實體上切換默認的獲取模式（我不記得爲此需要執行步驟）。

仍然是一個奇怪的錯誤，請發佈您的客戶端實體代碼更好的協助。
