Description
If I try to serialize collection of objects which have embedded collection, I get Undefined property error.
The problem is in vendor/symfony/json-streamer/Write/StreamWriterGenerator.php:186, which generate code like
foreach ($value->events as $value)
and redefine $value with embedded object.
How to reproduce
namespace App\Dto;
use Symfony\Component\JsonStreamer\Attribute\JsonStreamable;
#[JsonStreamable]
class User
{
public array $names;
}
namespace App\Controller;
use App\Dto\User;
use App\Repository\UserRepository;
use Symfony\Component\HttpFoundation\StreamedResponse;
use Symfony\Component\JsonStreamer\StreamWriterInterface;
use Symfony\Component\TypeInfo\Type;
class UserController
{
public function retrieveUsers(StreamWriterInterface $jsonStreamWriter): StreamedResponse
{
$user1 = new User();
$user1->names = ['John', 'Alex'];
$user2 = new User();
$user1->names = ['Mark', 'Andre'];
$users = [$user1, $user2];
$type = Type::list(Type::object(User::class));
$json = $jsonStreamWriter->write($users, $type);
return new StreamedResponse($json);
}
}
Possible Solution
Replace in vendor/symfony/json-streamer/Write/StreamWriterGenerator.php:186
$this->createDataModel($type->getCollectionValueType(), new VariableDataAccessor('value'), $options, $context),
to
$this->createDataModel($type->getCollectionValueType(), new VariableDataAccessor('value' . rand()), $options, $context),
