Symfony 3.4 Attempted to call an undefined method named "createQueryBuilder" of class "AppBundle\Entity\User"

Question

I generated entities and forms with symfony and tried to create a simple form. But I get an error which I cannot solve.

Attempted to call an undefined method named "createQueryBuilder" of class "AppBundle\Entity\User".

Controller:

public function groupedit(Request $request) {
    $group = new Group();
    $form = $this->createForm(GroupType::class, $group);

    $form->handleRequest($request);

    return $this->render(
                    'form.html.twig', array('form', $form->createView())
    );
}

Group Form Type

<?php

use Symfony\Component\Form\AbstractType;

use Symfony\Component\OptionsResolver\OptionsResolver;

class GroupType extends AbstractType
{
    /**
     * {@inheritdoc}
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('name')->add('systemgroup')->add('user');
    }/**
     * {@inheritdoc}
     */
    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'AppBundle\Entity\Group'
        ));
    }

    /**
     * {@inheritdoc}
     */
    public function getBlockPrefix()
    {
        return 'appbundle_group';
    }


}

Have someone an idea where the problem is?

Answer 1

The problems seems to be in your entity mapping where you declare

repositoryClass: User

while you should pass a valid Doctrine repository class instead of your entity class.

So either you remove repositoryClass from mapping if you don't need custom repository functions or create a valid class which should look like the following:

namespace AppBundle\Repository;

use Doctrine\ORM\EntityRepository;

class UserRepository extends EntityRepository
{
    // your custom repository functions here
}

and then proper mapping

repositoryClass: AppBundle\Repository\UserRepository
