Error on update query symfony2 - symfony

Question

I generated the CRUD for the entity Evenement(event) , which is working. But now I want to update a field in another entity called notification everytime an Evenement is added. Each Evenement has a categorie

}
In the createAction that was generated after the execution of the CRUD for the Evenement entity I added the update query :
public function createAction(Request $request)
{
$entity = new Evenement();
$request = $this->getRequest();
$form = $this->createForm(new EvenementType(), $entity);
$form->bindRequest($request);
$entity->upload();
$cat=$entity->getCategorie();
if ($cat) {
$catn = $cat->getNomCat();
$query = $this->container->get('doctrine')->getEntityManager()->createQuery( 'UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1 WHERE n.categorie LIKE :catn ' );
$query->setParameter('categorie', $catn);
$query->execute();
}
if ($form->isValid()) {
$em = $this->getDoctrine()->getEntityManager();
$em->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('mql14mqlme_adminshow', array('id' => $entity->getId())));
}
return array(
'entity' => $entity,
'form' => $form->createView(),
);
}
And the error I'm getting is this:
[Semantical Error] line 0, col 61 near 'categorie LIKE': Error:
Invalid PathExpression. Must be a StateFieldPathExpression.

Answer 1

You set the wrong parameter in the update query.
On this line:
$query = $this->container->get('doctrine')->getEntityManager()->createQuery(
'UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1
WHERE n.categorie LIKE :catn' );
$query->setParameter('categorie', $catn);
$query->execute();
It should be:
$query = $this->container->get('doctrine')->getEntityManager()->createQuery(
'UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1
WHERE n.categorie LIKE :catn' );
$query->setParameter('catn', $catn);
$query->execute();

Answer 2

n.categorie is an entity (of type Mql14\mqlmeBundle\Entity\Categorie) and you can't compare entities using LIKE.
Try replacing LIKE with =.
Change
UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1 WHERE n.categorie LIKE :catn
To
UPDATE Mql14mqlmeBundle:Notification n SET n.etat=1 WHERE n.categorie = :catn
