Neither the property “dispositif” nor one of the methods

Question

In a controller, I create a form:

$em = $this->getDoctrine()->getManager();

$formProjetSearch = $this->createForm(EgwProjetSearchType::class, $em, [
    'em' => $this->getDoctrine()->getManager(),
]);

In my EgwProjetSearchType, I have:

$builder->add('dispositif', 'entity', array(
  'class'   => 'LeaPrestaBundle:EgwDispositif', 
  'property'  => 'nomDispositif',
  'label'   => 'nomDispositif',
  'required'  => true,
  'empty_value' => '',
  'query_builder' => function(EntityRepository $er) 
  {
    return $er->createQueryBuilder('d')
      ->where('d.isActive = :isActive')
      ->setParameter('isActive', 1)
      ->orderBy('d.nomDispositif','ASC');
  },
));

And I've got this error:

Neither the property "dispositif" nor one of the methods "getDispositif()", "dispositif()", "isDispositif()", "hasDispositif()", "__get()" exist and have public access in class "Doctrine\ORM\EntityManager".

Nonetheless, the entity exists:

<?php

namespace Lea\PrestaBundle\Entity;

use Doctrine\Common\Collections\ArrayCollection;

use Doctrine\ORM\Mapping as ORM;

/**
 * Lea\PrestaBundle\Entity\EgwDispositif
 *
 * @ORM\Table(name="egw_dispositif")
 * @ORM\Entity
 */
class EgwDispositif
{
  /**
   * @var integer $idDispositif
   *
   * @ORM\Column(name="id_dispositif", type="integer", nullable=false)
   * @ORM\Id
   * @ORM\GeneratedValue(strategy="IDENTITY")
   */
  private $idDispositif;

  /**
  * @ORM\ManyToOne(targetEntity="EgwTypePrestation", inversedBy="dispositifs")
  * @ORM\JoinColumn(name="id_type_prestation", referencedColumnName="id")
  */
  private $idTypePrestation;

ETC ...

Thanks for your help !

Thakns for your messages, but, I just want to display in a form a entity in a listbox : i use the type EgwProjetSearchType, i add a field which is "dispositif" coming from entity EgwDispositif (which exists) and the return message is :

Neither the property "dispositif" nor one of the methods "getDispositif()", "dispositif()", "isDispositif()", "hasDispositif()", "__get()" exis``t and have public access in class "Doctrine\ORM\EntityManager"

So it's not a problem of argument EM passed in the form EgwProjetSearchType : Symfony says "the entity doesnt exists"....

I dont have to pass EwgDispositif ?? It was not the cas in Symfony 2 : i had :

$formProjetSearch = $this->createForm(new EgwProjetSearchType($this-

getDoctrine()->getManager()));

And this doesnt work anymore in 3.4. So i changed the code :

$formProjetSearch = $this->createForm(EgwProjetSearchType::class, $em, [
'em' => $this->getDoctrine()->getManager(),
]);

The second argument to createForm expects the data to be handled (e.g. your entity [though beware best practices]), you're passing the entity manager, which is probably not what you want. — Yoshi
yes i want to pass em in arg like : symfony.com/doc/3.4/form/form_dependencies.html — Alain Ouakbar Tabba Sardinalui
That's quite alright, just pass it in the options array, as you're already doing. 'em' => $this->getDoctrine()->getManager(),. — Yoshi
Again, you're passing $em as the second parameter to createForm. As per your code $em is the entity manager which obviously is not the form data! What you need is (for example), something like: $this->createForm(EgwProjetSearchType::class, new EgwDispositif(), [ 'em' => $this->getDoctrine()->getManager(), ]); — Yoshi
if you fixed the above issue with passing the entity manager as parameter and are now passing the actual entity instance there instead - you should also fix the form builder add to use "idDispositif" instead of "dispositif" (the addition should match your entity property). — ejuhjav

In your entity you need to define your getters and setters. Your entity class is private so you must define public getters and setters to access the private objects.
