Doctrine persist: - mysql

Question

I'm a beginner at Symfony. My problem is that I try to add values to my base MySQL and the problem is that I have the same id, but i verified my entity and i generate values #ORM/GeneratedValues, i don't understand where is my fault.
Routing :
esprit_parc_AjoutVoiture:
path: /Ajout_voiture/
defaults: { _controller: ParcBundle:Voiture:add }
My controller:
public function addAction (Request $Request)
{
$Voiture = new Voiture();
$form = $this->createForm(VoitureType::class,$Voiture);
$form->handleRequest($Request);
if ($form->isValid())
{
$em=$this->getDoctrine()->getManager();
$em->persist($Voiture);
$em->flush();
return $this->redirect($this->generateUrl(
'esprit_parc_Affichage'
));
}
return $this->render(
'ParcBundle:Voiture:ajout.html.twig',
array('form'=>$form->createView()
));
}
}
Entity Voiture:
<?php
namespace ParcBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Class voiture
* #package ParcBundle\Entity
* #ORM\Entity
* #ORM\Table(name="Voiture")
*/
class Voiture
{
/**
* #ORM\Column( type="integer")
* #ORM\Id
* #ORM\GeneratedValue
*/
private $id;
/**
* #ORM\Column(type="string",length=255)
*
*/
private $Serie;
/**
* #ORM\Column(type="datetime",length=255)
*/
private $DateMiseCirculation;
/**
* #ORM\Column(type="string",length=255)
*/
private $Marque;
/**
* #ORM\ManyToOne(targetEntity="ParcBundle\Entity\Modele" )
* #ORM\JoinColumn(name="id", referencedColumnName="id");
*/
private $modele;
public function getId()
{
return $this->id;
}
public function setId($id)
{
$this->id = $id;
}
public function getModele()
{
return $this->modele;
}
public function setModele($modele)
{
$this->modele = $modele;
}
public function getSerie()
{
return $this->Serie;
}
public function setSerie($Serie)
{
$this->Serie = $Serie;
}
public function getDateMiseCirculation()
{
return $this->DateMiseCirculation;
}
public function setDateMiseCirculation($DateMiseCirculation)
{
$this->DateMiseCirculation = $DateMiseCirculation;
}
public function getMarque()
{
return $this->Marque;
}
public function setMarque($Marque)
{
$this->Marque = $Marque;
}
}
Error:
An exception occurred while executing 'INSERT INTO Voiture (serie, date_mise_circulation, marque, id) VALUES (?, ?, ?, ?)' with params ["2313", "2012-12-03 02:02:00", "sd", 1]:
SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1' for key 'PRIMARY'
PS : i have values with id = "1" and it should increment automatically the id.
[EDIT]: Class VoitureType:
<?php
namespace ParcBundle\Form;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class VoitureType extends AbstractType
{
/**
* {#inheritdoc}
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('Serie')
->add('DateMiseCirculation')
->add('Marque')
->add('modele', EntityType::class, array(
"class" => "ParcBundle:Modele",
"choice_label"=> "libelle"
))
->add("Ajouter",SubmitType::class);
}
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'ParcBundle\Entity\Voiture'
));
}
/**
* {#inheritdoc}
*/
public function getBlockPrefix()
{
return 'parcbundle_voiture';
}
}

You have an old schema in your database and MySQL does not know that attribute id is auto increment value. To update your schema you can use one of methods:
Internal tool from Doctrine: php bin/console doctrine:schema:update --force.
Use DoctrineMigrationsBundle.
Remember that sometimes schema do not want to update because of foreign keys. Solution for this is just remove existing data.
