I am trying to Catch Doctrine exception in the controller by try catch, i am using Symfony 3
try {
$em = $this->get('doctrine.orm.entity_manager');
$em->persist( $transaction );
$em->flush();
} catch(Exception $e) {
return new JsonResponse(['error' => 'already exist']);
}
Thanks in advance
Finaly i got the solution for my problem and i wanna share the solution with you
try {
$em = $this->get('doctrine.orm.entity_manager');
$em->persist( $transaction );
$em->flush();
} catch(\Doctrine\DBAL\Exception\UniqueConstraintViolationException $e) {
throw new \Symfony\Component\HttpKernel\Exception\HttpException(409, "Transaction already exist" );
} catch(\Doctrine\DBAL\Exception\ConstraintViolationException $e ) {
throw new \Symfony\Component\HttpKernel\Exception\HttpException(409, "Bad request on Transaction" );
} catch(\Doctrine\DBAL\Exception\TableNotFoundException $e ) {
throw new \Symfony\Component\HttpKernel\Exception\HttpException(409, "Transaction Table not found" );
