Undefined method 'createQueryBuilder'

Question

I'm getting error for "$qb = $this->getDoctrine()->getManager()->createQueryBuilder();" this line in my project file . Can someone help me enter image description here

Answer 1

I think that $qb = $this->getDoctrine()->getManager() is getting an instance of Doctrine\Common\Persistence\ObjectManager, which doesn't have createQueryBuilder function.

From the manager, you can fetch repository for the entity you want to fetch. For example:

$qb = $this->getDoctrine()->getManager()->getRepository('App:MyClass')->createQueryBuidler()
