将过滤器添加到自定义控制器Dunglas API

我正在尝试向symfony2 Dunglas api包中的自定义控制器添加一个过滤器。 当我尝试获取对象集合时，我希望通过一些参数筛选实体。 例如，我有一个名为store的实体，它有一个属性phone，我想用这个参数过滤所有的存储。 url可能类似于：

…/web/app_dev.php/api/stores？\u format=json&telephone='1234567'

但我无法将筛选器添加到我的控制器。。。如果我尝试初始化过滤器，出现的错误如下：

{
  "@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",
  "trace": [

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

这是我的自定义控制器：

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()]);
    }
}

非常感谢你的帮助。

关于

您真的需要定制控制器吗？我认为你可以做你想做的事：

# 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" } ]

然后请求GET/api/stores？telephone=1234567，不带引号
