Invalid text representation: 7 ERROR: invalid input syntax for uuid: "test" - postgresql

Question

I'm using Symfony 3.2 with doctrine and postgresql.
I've created an entity with a uuid as primary key.
My entity definition:
/**
* Booking
*
* #ORM\Table(name="booking")
* #ORM\Entity(repositoryClass="AppBundle\Repository\BookingRepository")
* #ORM\EntityListeners({"AppBundle\EventListener\BookingListener"})
*/
class Booking {
/**
* #var string
*
* #ORM\Column(type="guid")
* #ORM\Id
* #ORM\GeneratedValue(strategy="UUID")
*/
private $id;
}
In my controller I have a show action like this:
/**
* #Route("booking/{id}", name="booking_show")
* #Method({"GET"})
*/
public function showAction(Request $request, Booking $booking) {
...
}
Everything seems to work fine, but when I try to load a route putting an wrong value as an ID (i.e. /booking/hello123), I receive a:
SQLSTATE[22P02]: Invalid text representation: 7 ERROR: invalid input syntax for uuid: "hello123"
Instead I would expect a 404.
Is there a way to capture this exception and redirect to a 404 page?

Answer 1

You can make use of Route Requirements - you can specify what conditions your parameter need to match to "qualify" to a certain route. This requirement is a regex, so all you need to do is to write a regex for an UUID
/**
* #Route("booking/{id}", name="booking_show", requirements={"id": "[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}"})
* #Method({"GET"})
*/
public function showAction(Request $request, Booking $booking) {
...
}
NOTE: Regex used above is just first result I found in Google for UUID regex, I didn't verify if it works
In the end if your id does not match regex, it does not match route and you should get 404.

Answer 2

you need to change the showaction
/**
* #Route("booking/{id}", name="booking_show")
* #Method({"GET"})
*/
public function showAction(Request $request,$bookingID) {
$em = $this->getDoctrine()->getManager();
$booking = $em->getRepository('AppBundle:Entity')->find(bookingID);
if(!$booking)
$this->createNotFoundException('No entity found with id :'.$bookingID);
...
}
