If you're using a DQL Query:
try {
$em->createQuery('...')->getSingleResult();
} catch(\Exception $e) {
return new Response('...');
}
Will throw an exception if no record is returned.
Same thing with "getResult" instead of "getSingleResult" should return
an ArrayCollection with a count of 0 if nothing is found:
$users = $em->createQuery('...')->getResult();
if($users->count() == 0)
throw new Exception('...');
(return a Response, throw an Exception, whatever you like, but those
are the tests I currently use).
