エンティティ内の属性をカウントする

Question

エンティティ "vehicule"とOneToMany関係にあるエンティティ "user"があります。私は各ユーザーの車両数を数えようとしています。これは私の機能です

$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 
        ,)); 

しかし、どのように私は私のaffiche.html.twigでそれを使用できるように私はそれを返すことができます。彼が持っている車両の数をforeachユーザーに表示したいからです。どうもありがとう これは

Answer 1

OOPの方法でこれを行うには正しい方法は、vehicules foreachの利用者の数を返すメソッドを定義することであるので、あなたはこれに可能性：

あなたのユーザークラス「エンティティ」でgetNumberOfVehicules関数を定義

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

は、あなたの小枝テンプレートであなただけの単純すなわち、その関数を呼び出します。

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

Answer 2

ですが、私はこのような何かをするだろう（クエリをテストしていませんが、それはかなり多くの仕事）

$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(); 

はビュー

に結果を渡す必要があります10

ビューでは、結果を反復処理できます。

Answer 3

$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(); 

ここでは、各ユーザーと対応する車両の番号との結果として配列を取得します。ちょうど結果を小枝に渡してからforeach名とcount.Allベスト。
