統計實體中的屬性

我有一個與實體「vehicule」具有OneToMany關係的實體「用戶」。我正在計算每個用戶的車輛數量。這是我的功能統計實體中的屬性

$emm = $this->getDoctrine(); 
      $directions = $emm->getRepository('OCUserBundle:User')->findAll(); 
      foreach($directions as $direction) { 
      $direction->getVehicule()->count(); 
       } 
return $this->render('DemandevehBundle:Demande:affiche.html.twig', array('demandes' => $demandes 
        ,));

但我怎麼能把它放在返回，以便我可以在我的affiche.html.twig中使用它。因爲我想向每位用戶展示他擁有的車輛數量。非常感謝這是我的實體VEHICULE

是希望的行爲是顯示用戶以及在同一頁面的車輛數量？如果大多數情況下需要編寫自定義查詢，則可以發佈實體。 – Vamsi

我已經發布了實體。是的，我想向用戶展示他在同一頁面中所有車輛的數量。 –

的正確方法在面向對象的方式做到這一點，是定義返回VEHICULES的foreach用戶數量的方法，所以你可以這樣：

在User類定義getNumberOfVehicules功能「實體」

public function getNumberOfVehicules() 
{ 
    return $this->vehicule->count(); 
}

然後在樹枝模板，你只需簡單地調用該函數，即：

{% for user in users %} 
    <p>{{user.username}} {{user.getNumberOfVehicules()}}</p> 
{% endfor %}

，以獲得期望的結果，我會做這樣的事情（沒有測試過的查詢，但應該差不多工作）

$em = $this->getDoctrine(); 
$userRepository = $em->getRepository('OCUserBundle:User'); 
$qb = $userRepository->createQueryBuilder('user') 
    ->leftJoin('user.vehicule','vehicule') 
    ->addSelect('COUNT(vehicule.id) AS vehicule_count') 
    ->groupBy('user.id') 
    ->getQuery(); 

$result = $qb->getResult();

結果傳遞到視圖

return $this->render('DemandevehBundle:Demande:affiche.html.twig', 
array('demandes' => $result));

在視圖中，您可以迭代結果。

$qb = $this->getEntityManager()->createQueryBuilder(); 

    return $qb->select('u.username as name, count(v.id) as count') 
      ->from('OCUserBundle:User', 'u') 
      ->leftJoin('u.vehicule', 'v') 
      ->groupBy('u.id') 
      ->getQuery() 
      ->getResult();

這裏我們得到一個數組作爲結果，每個用戶加上相應的車輛沒有。只需將結果傳遞給樹枝，然後使用名稱和數量。一切都是最好的。
