Doctrine/MySQL: field missing in ResultSetMapping - php

Question

I have a native query an want to fill a ResultSetMapping object with the results of my query.
Everything works as expected, but the field "distance". The field in the resulting array is always empty. When i run my query directly in MySQL there are results for "distance", so i guess my SQL is ok?
class PlaceRepository extends EntityRepository
{
public function getAllWithMainImage($lat, $lon)
{
try
{
$rsm = new ResultSetMapping;
$rsm->addScalarResult('slug', 'slug');
$rsm->addScalarResult('title', 'title');
$rsm->addScalarResult('rating', 'rating');
$rsm->addScalarResult('visited_at', 'visited_at');
$rsm->addScalarResult('img', 'img');
$rsm->addScalarResult('distance', 'distance');
return $this->getEntityManager()
->createNativeQuery('SELECT p.slug, p.title, p.rating, p.visited_at, pp.file AS img, ROUND(GLength(
LineString(
p.place_point,
GeomFromText("POINT(:lat :lon)")
)
) * 111.12, 1) AS distance
FROM place p
LEFT JOIN place_picture AS pp
ON p.id = pp.place_id
GROUP BY p.id
ORDER BY distance
LIMIT 20', $rsm)
->setParameter('lat', $lat)
->setParameter('lon', $lon)
->getResult();
}
catch(\Doctrine\ORM\NoResultException $e)
{
return false;
}
}
}
Repository function called from Crontroller:
class PlaceRestController extends Controller
{
public function getPlacesAction(ParamFetcher $paramFetcher)
{
$view = FOSView::create();
$view->setHeader('Access-Control-Allow-Origin', '*');
$em = $this->getDoctrine()->getManager();
$data = $em->getRepository('TouringPlaceBundle:Place')->getAllWithMainImage(48.39227479328352, 9.985520839691162); //hard-coded for debugging
print_r($data); //… [img] => xzz.jpg, [distance] =>
if($data)
{
$view->setStatusCode(200)->setData($data);
}
return $view;
}
}
Where is my mistake?

Answer 1

Can you add the part of your code where you are calling this method?
Where does the return value go? In an entity?
Evenf if I don't think so, the problem might come from the multiples quotes so :lat and :lon are not changed into the values you want them to be. Have you checked the profiler to be sure they are replaced?
