Query Filter Bundle

Query Filter Bundle brings request filtering and pagination functionality to Symfony 4 applications that use Doctrine 2.

Installation

First, install the dependency:

$ composer require artprima/query-filter-bundle

Usage examples

Basic example

  • Controller
<?php

namespace App\Controller;

use Artprima\QueryFilterBundle\QueryFilter\Config\BaseConfig; 
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Request as HttpRequest;
use Artprima\QueryFilterBundle\Request\Request;
use Artprima\QueryFilterBundle\QueryFilter\QueryFilter;
use Artprima\QueryFilterBundle\Response\Response;
use App\Repository\ItemRepository;

class DefaultController extends Controller
{
    // ...
    
    /**
     * @Route("/") 
     */
    public function indexAction(HttpRequest $request, ItemRepository $repository)
    {
        // set up the config
        $config = new BaseConfig();
        $config->setSearchAllowedCols(['t.name']);
        $config->setAllowedLimits([10, 25, 50, 100]);
        $config->setDefaultLimit(10);
        $config->setSortCols(['t.id'], ['t.id' => 'asc']);
        $config->setRequest(new Request($request));
        
        // here we provide a repository callback that will be used internally in the QueryFilter
        // The signature of the method must be as follows: function functionName(QueryFilterArgs $args): QueryResult;
        $config->setRepositoryCallback([$repository, 'findByOrderBy']);
        
        // Response must implement Artprima\QueryFilterBundle\Response\ResponseInterface
        $queryFilter = new QueryFilter(Response::class);
        /** @var Response $data the type of the variable is defined by the class in the first argument of QueryFilter's constructor */
        $response = $queryFilter->getData($config);
        $data = $response->getData();
        $meta = $response->getMeta();
        
        // ... now do something with $data or $meta
    }
    
    // ...
}
  • Repository
<?php

namespace App\Repository;

use App\Entity\Item;
use Artprima\QueryFilterBundle\Query\Mysql\PaginationWalker;
use Artprima\QueryFilterBundle\Query\ConditionManager;
use Artprima\QueryFilterBundle\Query\ProxyQueryBuilder;
use Artprima\QueryFilterBundle\QueryFilter\QueryFilterArgs;
use Artprima\QueryFilterBundle\QueryFilter\QueryResult;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Symfony\Bridge\Doctrine\RegistryInterface;

class ItemRepository extends ServiceEntityRepository
{
    /**
     * @var ConditionManager
     */
    private $pqbManager;

    public function __construct(RegistryInterface $registry, ConditionManager $manager)
    {
        parent::__construct($registry, Item::class);
        $this->pqbManager = $manager;
    }

    
    public function findByOrderBy(QueryFilterArgs $args): QueryResult
    {
        // Build our request
        $qb = $this->createQueryBuilder('t')
            ->setFirstResult($args->getOffset())
            ->setMaxResults($args->getLimit());

        $proxyQb = new ProxyQueryBuilder($qb, $this->pqbManager);
        $qb = $proxyQb->getSortedAndFilteredQueryBuilder($args->getSearchBy(), $args->getSortBy());
        $query = $qb->getQuery();
        $query->setHint(Query::HINT_CUSTOM_OUTPUT_WALKER, PaginationWalker::class);
        $query->setHint("mysqlWalker.sqlCalcFoundRows", true);
        $result = $query->getResult();
        $totalRows = $this->_em->getConnection()->query('SELECT FOUND_ROWS()')->fetchColumn();
        
        // return the wrapped result
        return new QueryResult($result, $totalRows);
    }    
    
    // ...
}

Now you can start your php server and filter the requests:

GET http://127.0.0.1:8000/?filter[t.name]=Doe&limit=100

This request will perform a LIKE request in DQL:

SELECT t FROM Item WHERE t.name LIKE "%Doe%" LIMIT 100

Advanced example

This filtering library is best used together with JMSSerializerBundle and FOSRestBundle. You will eventually write a lot less code that it was shown in the basic example.

To utilize the advanced usage, install all the packages.

composer require friendsofsymfony/rest-bundle
composer require jms/serializer-bundle
composer require artprima/query-filter-bundle
  • Turn them on in config/bundles.php:
<?php

return [
    // ...
    Artprima\QueryFilterBundle\ArtprimaQueryFilterBundle::class => ['all' => true],
    FOS\RestBundle\FOSRestBundle::class => ['all' => true],
    JMS\SerializerBundle\JMSSerializerBundle::class => ['all' => true],
    // ...
];

NOTE: you may need to add further bundles depending on your set up for FOSRestBundle and/or JMSSerializerBundle.

  • Controller:
<?php

namespace App\Controller;

use App\QueryFilter\Response;
use App\Repository\ItemRepository;
use Artprima\QueryFilterBundle\QueryFilter\Config\ConfigInterface as QueryFilterConfigInterface;
use FOS\RestBundle\Controller\Annotations as Rest;
use FOS\RestBundle\Controller\FOSRestController;
use FOS\RestBundle\Routing\ClassResourceInterface;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Artprima\QueryFilterBundle\Controller\Annotations\QueryFilter;

class ItemController extends FOSRestController implements ClassResourceInterface
{
    /**
     * @Rest\View(serializerEnableMaxDepthChecks=true)
     * @ParamConverter("config", class="App\QueryFilter\Config\ItemConfig",
     *                           converter="query_filter_config_converter",
     *                           options={"entity_class": "App\Entity\Item", "repository_method": "findByOrderBy"})
     * @QueryFilter()
     * @Rest\Get("/items")
     */
    public function cgetAction(QueryFilterConfigInterface $config)
    {
        return $config;
    }
}
  • Repository:
<?php

namespace App\Repository;

use App\Entity\Item;
use Artprima\QueryFilterBundle\Query\Mysql\PaginationWalker;
use Artprima\QueryFilterBundle\Query\ConditionManager;
use Artprima\QueryFilterBundle\Query\ProxyQueryBuilder;
use Artprima\QueryFilterBundle\QueryFilter\QueryFilterArgs;
use Artprima\QueryFilterBundle\QueryFilter\QueryResult;
use Doctrine\Bundle\DoctrineBundle\Repository\ServiceEntityRepository;
use Symfony\Bridge\Doctrine\RegistryInterface;

/**
 * @method Item|null find($id, $lockMode = null, $lockVersion = null)
 * @method Item|null findOneBy(array $criteria, array $orderBy = null)
 * @method Item[]    findAll()
 * @method Item[]    findBy(array $criteria, array $orderBy = null, $limit = null, $offset = null)
 */
class ItemRepository extends ServiceEntityRepository
{
    /**
     * @var ConditionManager
     */
    private $pqbManager;

    public function __construct(RegistryInterface $registry, ConditionManager $manager)
    {
        parent::__construct($registry, Item::class);
        $this->pqbManager = $manager;
    }

    public function findByOrderBy(QueryFilterArgs $args): QueryResult
    {
        $qb = $this->createQueryBuilder('t')
            ->setFirstResult($args->getOffset())
            ->setMaxResults($args->getLimit());

        $proxyQb = new ProxyQueryBuilder($qb, $this->pqbManager);
        $qb = $proxyQb->getSortedAndFilteredQueryBuilder($args->getSearchBy(), $args->getSortBy());
        $query = $qb->getQuery();
        $query->setHint(Query::HINT_CUSTOM_OUTPUT_WALKER, PaginationWalker::class);
        $query->setHint("mysqlWalker.sqlCalcFoundRows", true);
        $result = $query->getResult();
        $totalRows = $this->_em->getConnection()->query('SELECT FOUND_ROWS()')->fetchColumn();

        return new QueryResult($result, $totalRows);
    }
}

ItemConfig:

<?php

namespace App\QueryFilter\Config;

use Artprima\QueryFilterBundle\QueryFilter\Config\BaseConfig;

class ItemConfig extends BaseConfig
{
    public function __construct()
    {
        $this->setSearchAllowedCols(array(
            't.name',
        ));

        $this->setSortCols(
            array(
                't.id',
            ),
            array('t.id' => 'desc') // default
        );
    }
}

Simple Query Filter Examples

NOTE: assume that all the used fields are enabled in the configuration

Advanced Query Filter Example

Simple mode should be enough for most of the cases, however sometimes we might need to build more complicated filters having one and the same field used.

Pagination Examples

Sorting Example

NOTE: at the moment this bundle doesn't support more than one field for ORDER BY.
