Doctrine ORM SearchFilter

doctrine

API Platform provides a generic system to apply filters and sort criteria on collections. Useful filters for Doctrine ORM, MongoDB ODM and ElasticSearch are provided with the library. By default, all filters are disabled. They must be enabled explicitly.

// src/App/Entity.php
namespace App\Entity;
use ApiPlatform\Metadata\GetCollection;
use ApiPlatform\Metadata\QueryParameter;
use Doctrine\ORM\Mapping as ORM;
#[GetCollection(
    uriTemplate: 'books{._format}',
    parameters: [

Declare a QueryParameter with the :property pattern that matches the properties declared on the Filter. The filter is a service declared in the next class.

        ':property' => new QueryParameter(filter: 'app.search_filter'),
    ]
)]
#[ORM\Entity]
class Book
{
    #[ORM\Id, ORM\Column, ORM\GeneratedValue]
    public ?int $id = null;
    #[ORM\Column]
    public ?string $title = null;
    #[ORM\Column]
    public ?string $author = null;
}

// src/App/DependencyInjection.php
namespace App\DependencyInjection;
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;
function configure(ContainerConfigurator $configurator): void
{

This is the custom search filter we declare, if you prefer to use decoration, suffix the parent service with .instance. They implement the PropertyAwareFilterInterface that allows you to override a filter’s property.

    $services = $configurator->services();
    $services->set('app.search_filter')
             ->parent('api_platform.doctrine.orm.search_filter')

Search strategies may be defined here per properties, read more on the filter documentation.

             ->args([['author' => 'partial', 'title' => 'partial']])
             ->tag('api_platform.filter');
}

// src/App/Playground.php
namespace App\Playground;
use Symfony\Component\HttpFoundation\Request;
function request(): Request
{

Try changing the search value in the interactive Playground.

    return Request::create('/books.jsonld?author=a', 'GET');
}

// src/DoctrineMigrations.php
namespace DoctrineMigrations;
use Doctrine\DBAL\Schema\Schema;
use Doctrine\Migrations\AbstractMigration;
final class Migration extends AbstractMigration
{
    public function up(Schema $schema): void
    {
        $this->addSql('CREATE TABLE book (id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, title VARCHAR(255) NOT NULL, author VARCHAR(255) NOT NULL)');
    }
}

// src/App/Fixtures.php
namespace App\Fixtures;
use App\Entity\Book;
use Doctrine\Bundle\FixturesBundle\Fixture;
use Doctrine\Persistence\ObjectManager;
use function Zenstruck\Foundry\anonymous;
use function Zenstruck\Foundry\faker;
use function Zenstruck\Foundry\repository;
final class BookFixtures extends Fixture
{
    public function load(ObjectManager $manager): void
    {
        $bookFactory = anonymous(Book::class);
        if (repository(Book::class)->count()) {
            return;
        }
        $bookFactory->many(10)->create(fn () => [
            'title' => faker()->name(),
            'author' => faker()->firstName(),
        ]);
    }
}

// src/App/Tests.php
namespace App\Tests;
use ApiPlatform\Playground\Test\TestGuideTrait;
use ApiPlatform\Symfony\Bundle\Test\ApiTestCase;
use App\Entity\Book;
final class BookTest extends ApiTestCase
{
    use TestGuideTrait;
    public function testGetDocumentation(): void
    {
        static::createClient()->request('GET', '/books.jsonld');
        $this->assertResponseIsSuccessful();
        $this->assertMatchesResourceCollectionJsonSchema(Book::class, '_api_books{._format}_get_collection', 'jsonld');
        $this->assertJsonContains([
            'hydra:search' => [
                '@type' => 'hydra:IriTemplate',
                'hydra:template' => '/books.jsonld{?author,title}',
                'hydra:variableRepresentation' => 'BasicRepresentation',
                'hydra:mapping' => [
                    [

                        'variable' => 'author',
                        'property' => 'author',
                        'required' => false,
                    ],
                    [
                        '@type' => 'IriTemplateMapping',
                        'variable' => 'title',
                        'property' => 'title',
                        'required' => false,
                    ],
                ],
            ],
        ]);
    }
}
