Method 'QueryBuilder' not found in class ObjectRepository - php

Question

New to Symfony & Doctrine
I trying to fetch a selection of objects from a MySQL database via Doctrine in a Symfony project. I am doing this with createQueryBuilder;
$repository = $this->getDoctrine()
->getRepository('mcsyncBundle:DB');
$query = $repository->createQueryBuilder('p')
->select('p')
->where('(p.created=:)' . $till)
->setParameter('created', $till)
->orderBy('p.created', 'ASC')
->getQuery();
$PackDB = $query->getResult();
But I keep getting the error:
*Method 'QueryBuilder' not found in class \Doctrine\Common\Persistence\ObjectRepository*.
Anyone that can explain (fix) this problem?
EDIT: This error is coming from inside PHPStorm by the way and NOT from Symfony itself

Answer 1

I suppose you wrote that code in a Controler file. QueryBuilders are meant to be in Repository files. For /Entity/Plop.php, you should have /Entity/PlopRepository.php as well.
PlopRepository.php
namespace Foo\BarBundle\Entity;
use Doctrine\ORM\EntityRepository;
class PlopRepository extends EntityRepository
{
public function getCreatedP()
{
$qb = $this->createQueryBuilder('p')
->select('p')
->where('p.created = :created')
->setParameter('created', $till)
->orderBy('p.created', 'ASC');
return $qb->getQuery()
->getResults();
}
// ...
}
EDIT 1 : and there was a mistake in your ->where('...') statement I fixed ;)
EDIT 2 : to be complete, controller part :
TotoController.php
public function getPlopAction()
{
$entityManager = $this->getDoctrine()->getManager();
$plopRepository = $entityManager->getRepository('FooBarBundle:Plop');
$plops = $plopRepository->getCreatedP();
// ...
}
