Apply filters in custom data provider

Hi, i have a problem.

I can not figure it out how to apply filters for custom collection data provider. In this examples provider does not do anything but filters are problem.

This is my resource file:

resources:
    LocationBundle\Entity\Location:
        itemOperations:
            get:
                method: 'GET'
                normalization_context:
                    groups: ['location-item']
        collectionOperations:
            get:
                method: 'GET'
                normalization_context:
                    groups: ['location-list']
        attributes:
            filters: ['location.search', 'location.boolean']

My provider:

class LocationCollectionDataProvider implements CollectionDataProviderInterface
{
    /**
     * @var EntityRepository
     */
    private $locationRepository;

    public function __construct(EntityRepository $locationRepository)
    {
        $this->locationRepository = $locationRepository;
    }

    public function getCollection(string $resourceClass, string $operationName = null)
    {
        if (Location::class !== $resourceClass) {
            throw new ResourceClassNotSupportedException();
        }

        return $this->locationRepository->findAll();

    }

}

services:

    location.repository:
        class: Doctrine\ORM\EntityRepository
        factory: ["@doctrine.orm.entity_manager", getRepository]
        arguments: [ LocationBundle\Entity\Location ]

    location.collection_data_provider:
        class: 'LocationBundle\DataProvider\LocationCollectionDataProvider'
        public: false
        arguments: [ "@location.repository" ]
        tags:
            -  { name: 'api_platform.collection_data_provider', priority: 2 }

Tnx! 😄

Hi,

I’m also interested in this issue because it’s not explained in the docs how you can create a custom filter and apply it to a custom data provider. You have only an example where you create a custom filter but it’s tied to doctrine.

I’ve found that for Symfony 3.4+ it can be added to the service definition this way:

services:
    AppBundle\DataProvider\ShopContentLibraryItemProvider:
        tags: [ { name: 'api_platform.collection_data_provider', priority: 3 } ]
        autoconfigure: false
        arguments:
            $collectionExtensions: !tagged api_platform.doctrine.orm.query_extension.collection

Unfortunately the project is on Symfony 3.3, so apparently I have to create a compiler pass 🙄
