Doctrine Extension with API Platform - SQL - php

Question

I'm working on some API Platform project.
I 'm using my API point /references to get some data containing subentities.
But the issue is that I use a Doctrine extension to filter my list. Using this extension I can filter which references I get.
But in the subentity Stock I stil have some data that I dont want.
My goal is to get all stocks that have the warehouse.owner = $owner.
Here is the code :
private function addWhere(QueryBuilder $queryBuilder, string $resourceClass): void
{
if ($this->security->isGranted('SCOPE admin') || !$this->security->isGranted('SCOPE logistician')) {
return;
}
/** #var Client $client */
$client = $this->security->getUser();
$rootAlias = $queryBuilder->getRootAliases()[0];
switch ($resourceClass) {
case Entry::class:
case Inventory::class:
$queryBuilder->join(sprintf('%s.stock', $rootAlias), 's');
break;
case Reference::class:
// I'm here
$queryBuilder->join(sprintf('%s.stocks', $rootAlias), 's');
break;
default:
return;
break;
}
$queryBuilder->join('s.warehouse', 'w', Expr\Join::WITH, 'w.owner = :owner');
$queryBuilder->setParameter('owner', $client->getSubject());
}
Here is the response :

How can I filter the subentity result by just using my extension and DQL ? Thanks

Answer 1

Extension is used for retrieve main items, not associated collection.
Instead you can use data transformer.
class ReferenceOutput {
public $stocks;
}
//Next class
use ApiPlatform\Core\DataTransformer\DataTransformerInterface;
use Symfony\Component\Security\Core\Security;
class ReferenceOutputTransformer implements DataTransformerInterface
{
private string $security;
public function __construct(Security $security)
{
$this->security = $security;
}
/**
* Transforms the given object to something else, usually another object.
* This must return the original object if no transformations have been done.
*
* #param object $object Snapshot
*
* #param string $to
* #param array $context
*
* #return object
*/
public function transform($object, string $to, array $context = [])
{
/** #var Reference $reference */
$reference = $object;
/** #var Client $client */
$client = $this->security->getUser();
$referenceOutput = new ReferenceOutput();
$stocks = $reference->getStoks()->filter(
static function($key, $stock) use ($client) {
return $stock->getWarehouse()->getOwner() === $client->getSubject();
});
$referenceOutput->stocks = $stocks;
return $referenceOutput;
}
/**
* Checks whether the transformation is supported for a given data and context.
*
* #param object|array $data object on normalize / array on denormalize
*
* #param string $to
* #param array $context
*
* #return bool
*/
public function supportsTransformation($data, string $to, array $context = []): bool
{
return ReferenceOutput::class === $to && $data instanceof Reference;
}
}
