Запрос не работает с Doctrine2

Question

Я разрабатываю небольшой веб-сайт, чтобы узнать Symfony2, и у меня проблема с запросом Doctrine, и я не понимаю, почему.

Это мой EventRepository

class EventRepository extends \Doctrine\ORM\EntityRepository 
{ 
    public function findByBounds($lat, $lng, $zoom) 
    { 
     $em = $this->getEntityManager(); 
     $bounds = 0.025; 

     $latBound1 = $lat + $bounds * 2 ** $zoom/2; 
     $latBound2 = $lat - $bounds * 2 ** $zoom/2; 
     $lngBound1 = $lng + $bounds * 2 ** $zoom/2; 
     $lngBound2 = $lng - $bounds * 2 ** $zoom/2; 

     $latBoundMin = $latBound1 < $latBound2 ? $latBound1 : $latBound2; 
     $latBoundMax = $latBound1 > $latBound2 ? $latBound1 : $latBound2; 
     $lngBoundMin = $lngBound1 < $lngBound2 ? $lngBound1 : $lngBound2; 
     $lngBoundMax = $lngBound1 > $lngBound2 ? $lngBound1 : $lngBound2; 

     $query = $em->createQuery(
      "SELECT e 
      FROM AppBundle:Event e 
      WHERE (e.lat BETWEEN :latBoundMin AND :latBoundMax) AND (e.lng BETWEEN :lngBoundMin AND :lngBoundMax) 
      ORDER BY e.date ASC"); 

     $query->setParameters(array(
      "latBoundMin" => $latBoundMin, 
      "latBoundMax" => $latBoundMax, 
      "lngBoundMin" => $lngBoundMin, 
      "lngBoundMax" => $lngBoundMax, 
     )); 

     return $query->getResult(); 
    } 
} 

Это мой indexAction в моем EventController

public function indexAction(Request $request) 
{ 
    $em = $this->getDoctrine()->getManager(); 
    $lat = $request->request->get("locationLat"); 
    $lng = $request->request->get("locationLng"); 
    $zoom = 0; 

    // search events by lat, lng and bounds 
    // $events = $em->getRepository('AppBundle:Event')->findAll(); 
    // do { 
    // 
     $latBound1 = $lat + 0.025 * 2 ** $zoom/2; 
     $latBound2 = $lat - 0.025 * 2 ** $zoom/2; 
     $lngBound1 = $lng + 0.025 * 2 ** $zoom/2; 
     $lngBound2 = $lng - 0.025 * 2 ** $zoom/2; 

     $latBoundMin = $latBound1 < $latBound2 ? $latBound1 : $latBound2; 
     $latBoundMax = $latBound1 > $latBound2 ? $latBound1 : $latBound2; 
     $lngBoundMin = $lngBound1 < $lngBound2 ? $lngBound1 : $lngBound2; 
     $lngBoundMax = $lngBound1 > $lngBound2 ? $lngBound1 : $lngBound2; 
    // 
    //  $events = $em->getRepository("AppBundle:Event")->findByBounds($lat, $lng, $zoom); 
    //  $numEvents = 0; 
    //  foreach ($events as $event) { 
    //   $numEvents++; 
    //  } 
    // } while ($numEvents < 5 && $zoom <= 3); 

    $events = $em->getRepository("AppBundle:Event")->findByBounds($lat, $lng, $zoom); 
    $numEvents = 0; 
    foreach ($events as $event) { 
     $numEvents++; 
    } 

    return $this->render('event/index.html.twig', array(
     'events' => $events, 
     "lat" => $lat, 
     "lng" => $lng, 
     "zoom" => $zoom, 
     "numEvents" => $numEvents, 
     "lat1" => $latBoundMin, 
     "lat2" => $latBoundMax, 
     "lng1" => $lngBoundMin, 
     "lng2" => $lngBoundMax, 
    )); 
} 

Все события в БД ...

И запрос в SQL, который работает ...

Я не могу понять, почему мой запрос в DQL не работает правильно :(

Answer 1

Изменить

$query->setParameters(array(
      "latBoundMin" => $latBoundMin, 
      "latBoundMax" => $latBoundMax, 
      "lngBoundMin" => $lngBoundMin, 
      "lngBoundMax" => $lngBoundMax, 
     )); 

в

$query->setParameter('latBoundMin', $latBoundMin) 
     ->setParameter('latBoundMax', $latBoundMax) 
     ->setParameter('lngBoundMin', $lngBoundMin) 
     ->setParameter('lngBoundMax', $lngBoundMax);
