SF2 form : error Neither the property ... nor one of the methods "get

Question

I try to do a contact form with Symfony 2.4.1 and I have the following error :

Neither the property "contact" nor one of the methods "getContact()", "isContact()", "hasContact()", "__get()" exist and have public access in class "Open\OpcBundle\Entity\Contact". 

I understand the error itself, but I can't find any resources to solve it in SF2 forms documentation or on the web:

The controller code looks like this:

[..]

class OpcController extends Controller {
public function contactAction(Request $request) {      
  $contact = new Contact();

  $form = $this->createForm(new ContactType(), $contact);

  $form->handleRequest($request);

  return $this->render("OpenOpcBundle:Opc:contact.html.twig",
        array("formu" => $form->createView(),
        )
  );      
}   
}  

The Contact Entity looks like this :

[...] 
class Contact {
  protected $nom;
  protected $courriel;
  protected $sujet;
  protected $msg;

public function getNom() {
  return $this->nom;
}

public function setNom($nom) {
  $this->nom = $nom;
}

public function getCourriel() {
  return $this->courriel;
}

public function setCourriel($courriel) {
  $this->courriel = $courriel;
}

public function getSujet() {
  return $this->sujet;
}

public function setSujet($sujet) {
  $this->sujet = $sujet;
}

public function getMsg() {
  return $this->msg;
}

public function setMsg($msg) {
   $this->msg = $msg;
}  
} 

And the Form class code:

public function buildForm(FormBuilderInterface $builder, array $options) {
  $builder->add('contact');
  ->add('nom', 'text'))
    ->add('courriel', 'email')
    ->add('sujet', 'text')
          ->add('msg', 'textarea')
    ->add('submit', 'submit');
}

public function getName() {
  return "Contact";
}

public function setDefaultOptions(OptionsResolverInterface $resolver) {
  $resolver->setDefaults(array('data_class' => 'Open\OpcBundle\Entity\Contact', ));
}
} 

Where is my mistake? Thanks

Answer 1

Your error is correct and telling you that you entity Contact does not have the contact property and no related getter setter method while in your buildForm() you have used contact property like $builder->add('contact'); but there is no related property exists in the entity,Define the property first in your entity

class Contact {
  protected $nom;
  protected $courriel;
  protected $sujet;
  protected $msg;
  protected $contact;

public function getContact() {
  return $this->contact;
}

public function setContact($contact) {
  $this->contact= $contact;
}
/* ...
remaining methods in entity 

*/
}

or if its a non mapped field then you have to define this field in builder as non mapped

$builder->add('contact','text',array('mapped'=>false));

By defining above you will not need to update your entity
