In cotroller i have getVilla metod which return json response.
I get one villa by id from database in $villa variable, and this work fine. When i print_r($villa) i have villa object with all data.
But when i push $villa in response with
json_encode: json_encode(['villa' => $villa]), villa is empty...
villa: {}

* #param $id
* #param EntityManagerInterface $em
* #return Response
*/
public function getVilla($id, EntityManagerInterface $em): Response
{
$repository = $em->getRepository(Villa::class);
$villa = $repository->findOneBy(['id' => $id]);
return new Response(json_encode([
'villa' => $villa,
]));
}

Answer 1

You are returning a json response from a response so you should use JsonResponse instead:
use Symfony\Component\HttpFoundation\JsonResponse;
//...
return new JsonResponse([
'villa' => $villa,
]);
However, your array contain an object $villa, not an array.
So you should either make a new array from your villa object or serialize it.
The easy way would be to make a new array from villa :
public function getVilla($id, EntityManagerInterface $em): Response
{
$repository = $em->getRepository(Villa::class);
$villa = $repository->findOneBy(['id' => $id]);
if($villa){
$villaArray['id'] = $villa->getId();
$villaArray['cityNameOrSomething'] = $villa->getCityName();
//Do the same for other attribute you want to get in your json
}else{
$villaArray = [];
}
return new Response([
'villa' => $villaArray,
]);
}
The other way would be to use the serializer component so that you do not have to make a new array.
Just follow the Symfony Documentation on the usage to find the one you want to use.
