Question

i made a new bundle,
made a new controller
made few entities

entity does get in the database when i use php console dotrine:schema:update –force

i make a form,
form pops great,
when i submit i use

if ($form->isValid()) {
                // perform some action, such as saving the task to the database

                $em = $this->getDoctrine()->getEntityManager();
                $em->persist($type);
                $em->flush();


                return $this->redirect($this->generateUrl('_success'));
            }

i get a big fat error :

Class Naus\Biobalance\Entity\Sample is not a valid entity or mapped
super class.

i’ve double checked my top..
and use Naus\bundle\Entity\Sample; is mentioned like it is supposed to be ?
no clear answers online, hope someone can help..

the first lines of the entity (on request)

<?php 

namespace Naus\Biobalance\Entity;

use Doctrine\ORM\EntityManager;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="sample")
 */
class Sample
{

regarding the appkernel :

<?php

use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {

Answer 1

Apparently, setting the auto_mapping setting found in config.yml solves the problem.
