添加過濾器到自定義控制器Dunglas API

Question

我想在symfony2 Dunglas api包中添加一個自定義控制器的過濾器。 我想通過一些參數過濾我的實體，當我嘗試獲取對象集合。 例如，我有一個名爲「商店」的實體具有「電話」屬性，我想用此參數過濾所有商店。 的URL可能是這樣的：？

... /網絡/ app_dev.php/API /店_format = JSON &電話= '1234567'

但我可以」過濾器添加到我的控制器...如果我嘗試初始化一個過濾器，出現錯誤是這個：

{ 
    "@context": "/DKCore/web/app_dev.php/api/contexts/Error", 
    "@type": "Error", 
    "hydra:title": "An error occurred", 
    "hydra:description": "Error: Call to a member function getDescription() on a non-object",

    {

    {

     "file": "/var/www/html/DKCore/web/app_dev.php", 
     "line": 0, 
     "args": [] 
    } 
    ] 
} 

這是我的自定義控制器：

namespace AppBundle\Controller; 

use Dunglas\ApiBundle\Controller\ResourceController; 
use Dunglas\ApiBundle\Event\DataEvent; 
use Dunglas\ApiBundle\Event\Events; 
use Symfony\Component\HttpFoundation\Request; 
use Dunglas\ApiBundle\Api\Resource; 

class StoreController extends ResourceController 
{ 

    public function getAction(Request $request, $number) 
    { 
     $em = $this->getDoctrine()->getManager(); 
     $store = $em->getRepository('AppBundle:Store')->findOneBySiteId($number); 
     $groups = ['groups' => ['details']]; 
     $resource = new Resource('AppBundle\Entity\Store'); 
     $resource->initNormalizationContext($groups); 
     $object = $this->findOrThrowNotFound($resource, $store->getId()); 
     $this->get('event_dispatcher')->dispatch(Events::RETRIEVE, new DataEvent($resource, $object)); 
     return $this->getSuccessResponse($resource, $object); 
    } 

    public function getListAction(Request $request) 
    { 
     $groups = ['groups' => ['list']]; 
     $filters=['telephone'=>'948314796']; 
     $resource = new Resource('AppBundle\Entity\Store'); 
     $resource->initFilters($filters); 
     $resource->initNormalizationContext($groups); 
     $data = $this->getCollectionData($resource, $request); 
     if (
      $request->get($this->container->getParameter('api.collection.pagination.page_parameter_name')) && 
      0 === count($data) 
     ) { 
      throw $this->createNotFoundException(); 
     } 
     $this->get('event_dispatcher')->dispatch(Events::RETRIEVE_LIST, new DataEvent($resource, $data)); 
     return $this->getSuccessResponse($resource, $data, 200, [], ['request_uri' => $request->getRequestUri()]); 
    } 
} 

非常感謝您的幫助。 Regards

你真的需要一個自定義控制器嗎？我想你可以use the builtin search filter做你想要什麼：

# app/config/services.yml 

services: 
    resource.store.search_filter: 
     parent: "api.doctrine.orm.search_filter" 
     arguments: [ { telephone: "exact" } ] 

    resource.store: 
     parent: "api.resource" 
     arguments: [ "AppBundle\Entity\Store" ] 
     calls: 
      -  method: "initFilters" 
        arguments: [ [ "@resource.store.search_filter" ] ] 
     tags:  [ { name: "api.resource" } ] 

然後要求GET /api/stores?telephone=1234567（不帶引號）。
