symfony entities many to many, i add new fields - php

Question

I try this code: Symfony: ManyToMany table extra columns
This new field is because the user have a diferent role for diferent events.
In the fist time i can add add the new fields on table user.evento, but now i cant. And i dont find the problem.
I get this fail:
An exception occurred while executing 'INSERT INTO user_evento (user_id, evento_id) VALUES (?, ?)' with params [3, 18]: SQLSTATE[HY000]: General error: 1364 Field 'tipoinvitado' doesn't have a default value
why not detecting the other 2 fields ?
capture of my sql update with the new fields
my entity UserHasEvento:
/**
* #ORM\Entity
* #ORM\Table(name="user_evento")
*/
class UserHasEvento
{
/**
* #ORM\Id
* #ORM\Column(name="id", type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Evento", cascade={"persist"}, fetch="LAZY")
* #ORM\JoinColumn(name="evento_id", referencedColumnName="id")
*/
private $eventos;
/**
* #ORM\ManyToOne(targetEntity="User", cascade={"persist","remove"}, fetch="LAZY" )
* #ORM\JoinColumn(name="user_id", referencedColumnName="id",nullable=true)
*/
private $users;
/**
* #ORM\Column(name="tipoinvitado", type="string", length=255, nullable=true)
*/
private $tipoinvitado;
/**
* #var \DateTime|null
*
* #ORM\Column(name="fechainscripcion", type="datetime", nullable=true)
*/
private $fechainscripcion;
public function setTipoinvitado(string $tipoinvitado): self
{
$this->tipoinvitado = $tipoinvitado;
return $this;
}
public function getTipoinvitado(): string
{
return $this->tipoinvitado;
}
public function getFechainscripcion()
{
return $this->fechainscripcion;
}
public function setFechainscripcion($fechainscripcion): self
{
$this->fechainscripcion = $fechainscripcion;
return $this;
}
public function __construct()
{
$this->createdAt= new \DateTime('now');
}
}
My controller update.
public function asignarUsuario(Request $request, Evento $evento, Userhasevento $userhasevento){
$user_repo = $this->getDoctrine()->getRepository(User::class);
$users = $user_repo->findAll();
$evento = $this->getDoctrine()->getRepository(Evento::class)->findOneById($evento);
$form = $this->createForm(AsignarEventoFormType::class, $evento);
$form->handleRequest($request);
if($form->isSubmitted() && $form->isValid()){
$users = $evento->GetUsers();
foreach($users as $user){
$user->addEvento($evento);
$evento->addUser($user);
$userhasevento->SetTipoinvitado('normal');
$userhasevento->setFechainscripcion(new \DateTime('now'));
$em = $this->getDoctrine()->getManager();
$em->persist($evento);
$em->persist($userhasevento);
$em->flush();
}
return $this->redirect($this->generateUrl('evento_detalle', ['id' => $evento->getId()]));
}
return $this->render('evento/AsignarEvento.html.twig',[
'form' => $form->createView()
]);
}

Answer 1

Is your field $tipoinvitado disappear?
You might have changed your relation and the null boolean of $tipoinvitado at some point. You made your migration after changing any relation?
This can happen when you change your relations and had already data stored in you DB in a field that disappear because of you relation change.
I might be able to help you, don't hesitate giving more info

Answer 2

You have the answer in the error, the $tipoinvitado field has the annotation nullable=false which is a not null constraint (prevent storing null value), so it should absolutely have a value.
So you either give it a default value, give a value or change it to nullable=true.
