Это мое первое приложение Symfony.Я пытаюсь создать менеджер интервенций, поэтому создал три объекта: Intervention, Comment и User.
. Пользователи управляются FOSUserBundle.

Проблема заключается вкогда я пытаюсь получить доступ к Intervention с помощью Doctrine, у меня появляется циклическая ссылка.
Я думал, что comments при вмешательстве возвращает коллекцию пользователей, которая также возвращает comments ...
$repository = $this->getDoctrine()->getRepository(Intervention::class);
$intervention = $repository->findBy(['statut' => 1]);
return $this->json($intervention);
Есть ли у вас какие-либо предложения, чтобы заставить мой код работать, пожалуйста?Спасибо.
Решение:
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Encoder\JsonEncoder;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
public function getLocations(){
$encoder = new JsonEncoder();
$normalizer = new ObjectNormalizer();
$normalizer->setCircularReferenceHandler(function ($object, string $format = null, array $context = array()) {
return $object->getId();
});
$serializer = new Serializer(array($normalizer), array($encoder));
$repository = $this->getDoctrine()->getRepository(Intervention::class);
$intervention = $repository->findBy(['statut' => 1]);
$response = new Response($serializer->serialize($intervention, 'json'));
$response->headers->set('Content-Type', 'application/json');
return $response;
}
Спасибо за вашу помощь.
