Sonata Admin Bundle Many-to-Many relationship not saving foreign ID - php

Question

Here is my problem. I have two entities with a Many-To-Many relationship and would like to insert in a field multiple information.
I use sonata admin for administration, and here is my code:
Notification Class:
<?php
namespace App\BlogBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Notification
*
* #ORM\Table(name="notification")
* #ORM\Entity
*/
class Notification {
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="message", type="string", length=255)
*/
private $message;
/**
* #ORM\ManyToMany(targetEntity="Etudiant",mappedBy="notification")
*/
private $etudiant;
/**
* Get id
*
* #return integer
*/
public function getId() {
return $this->id;
}
/**
* Set message
*
* #param string $message
* #return Notification
*/
public function setMessage($message) {
$this->message = $message;
return $this;
}
/**
* Get message
*
* #return string
*/
public function getMessage() {
return $this->message;
}
public function __toString() {
return $this->message;
}
public function __construct() {
$this->etudiant = new \Doctrine\Common\Collections\ArrayCollection();
}
public function setEtudiant($etudiant) {
if (count($etudiant) > 0) {
foreach ($etudiant as $i) {
$this->addEtudiant($i);
}
}
return $this;
}
/**
* Add etudiant
*
* #param \App\BlogBundle\Entity\Etudiant $etudiant
* #return Notification
*/
public function addEtudiant(\App\BlogBundle\Entity\Etudiant $etudiant)
{
$this->etudiant[] = $etudiant;
return $this;
}
/**
* Remove etudiant
*
* #param \App\BlogBundle\Entity\Etudiant $etudiant
*/
public function removeEtudiant(\App\BlogBundle\Entity\Etudiant $etudiant)
{
$this->etudiant->removeElement($etudiant);
}
/**
* Get etudiant
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getEtudiant()
{
return $this->etudiant;
}
}
Etudiant Class:
<?php
namespace App\BlogBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**

*
* #ORM\Table(name="etudiant")

*/
class Etudiant{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="nom", type="string", length=255)
*/
private $nom;
/**
* #var string
*
* #ORM\Column(name="prenom", type="string", length=255)
*/
private $prenom;
/**
* #var \DateTime
*
* #ORM\Column(name="date_naissance", type="datetime")
*/
private $dateNaissance;
/**
* #var string
*
* #ORM\Column(name="adresse", type="text")
*/
private $adresse;
/**
* #var string
*
* #ORM\Column(name="email", type="string", length=255)
*/
private $email;
/**

/**

*/
private $dateInscription;
/**
* #var int
*
* #ORM\Column(name="frais_scolarite", type="integer")
*/
private $fraisScolarite;
/**
* #ORM\ManyToMany(targetEntity="Notification",inversedBy="etudiant")
*#ORM\JoinColumn(name="user_notificaiton")
*/
private $notification;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set nom
*
* #param string $nom
* #return Etudiant
*/
public function setNom($nom)
{
$this->nom = $nom;
return $this;
}
/**
* Get nom
*
* #return string
*/
public function getNom()
{
return $this->nom;
}
/**
* Set prenom
*
* #param string $prenom
* #return Etudiant
*/
public function setPrenom($prenom)
{
$this->prenom = $prenom;
return $this;
}
/**
* Get prenom
*
* #return string
*/
public function getPrenom()
{
return $this->prenom;
}
/**
* Set dateNaissance
*
* #param \DateTime $dateNaissance
* #return Etudiant
*/
public function setDateNaissance($dateNaissance)
{
$this->dateNaissance = $dateNaissance;
return $this;
}
/**
* Get dateNaissance
*
* #return \DateTime
*/
public function getDateNaissance()
{
return $this->dateNaissance;
}
/**
* Set adresse
*
* #param string $adresse
* #return Etudiant
*/
public function setAdresse($adresse)
{
$this->adresse = $adresse;
return $this;
}
/**
* Get adresse
*
* #return string
*/
public function getAdresse()
{
return $this->adresse;
}
/**
* Set email
*
* #param string $email
* #return Etudiant
*/
public function setEmail($email)
{
$this->email = $email;
return $this;
}
/**
* Get email
*
* #return string
*/
public function getEmail()
{
return $this->email;
}
/**
* Set telephone
*
* #param integer $telephone
* #return Etudiant
*/
public function setTelephone($telephone)
{
$this->telephone = $telephone;
return $this;
}
/**
* Get telephone
*
* #return integer
*/
public function getTelephone()
{
return $this->telephone;
}
/**
* Set numInscription
*
* #param string $numInscription
* #return Etudiant
*/
public function setNumInscription($numInscription)
{
$this->numInscription = $numInscription;
return $this;
}
/**
* Get numInscription
*
* #return string
*/
public function getNumInscription()
{
return $this->numInscription;
}
/**
* Set dateInscription
*
* #param \DateTime $dateInscription
* #return Etudiant
*/
public function setDateInscription($dateInscription)
{
$this->dateInscription = $dateInscription;
return $this;
}
/**
* Get dateInscription
*
* #return \DateTime
*/
public function getDateInscription()
{
return $this->dateInscription;
}
/**
* Set fraisScolarite
*
* #param integer $fraisScolarite
* #return Etudiant
*/
public function setFraisScolarite($fraisScolarite)
{
$this->fraisScolarite = $fraisScolarite;
return $this;
}
/**
* Get fraisScolarite
*
* #return integer
*/
public function getFraisScolarite()
{
return $this->fraisScolarite;
}
public function __toString() {
return $this->nom;
}
public function __construct() {
$this->notification = new \Doctrine\Common\Collections\ArrayCollection();
}
function setNotification($notification) {
if (count($notification) > 0) {
foreach ($notification as $i) {
$this->addEtudiant($i);
}
}
return $this;
}
/**
* Add notification
*
* #param \App\BlogBundle\Entity\Notification $notification
* #return Etudiant
*/
public function addNotification(\App\BlogBundle\Entity\Notification $notification)
{
$this->notification[] = $notification;
return $this;
}
/**
* Remove notification
*
* #param \App\BlogBundle\Entity\Notification $notification
*/
public function removeNotification(\App\BlogBundle\Entity\Notification $notification)
{
$this->notification->removeElement($notification);
}
/**
* Get notification
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getNotification()
{
return $this->notification;
}
}
Finally My NotificationAdmin:
<?php
namespace App\BlogBundle\Admin;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Show\ShowMapper;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
class NotificationAdmin extends Admin {
// Fields to be shown on create/edit forms
protected function configureFormFields(FormMapper $formMapper) {
$formMapper
->add('message', 'text')
->add('etudiant', 'sonata_type_model', array(
'required' => false,
'multiple' => true
))
;
}
// Fields to be shown on filter forms
protected function configureDatagridFilters(DatagridMapper $datagridMapper) {
$datagridMapper
->add('message')
->add('etudiant')
;
}
// Fields to be shown on lists
protected function configureListFields(ListMapper $listMapper) {
$listMapper
->addIdentifier('message')
->add('etudiant')
;
}
// Fields to be shown on show action
protected function configureShowFields(ShowMapper $showMapper) {
$showMapper
->add('id')
->add('nom')
;
}
public function prePersist($notification){
$this->preUpdate($notification);
}
public function preUpdate($notification){
$notification->setEtudiant($notification);
}
public function getBatchActions() {
// retrieve the default batch actions (currently only delete)
$actions = parent::getBatchActions();
if (
$this->hasRoute('edit') && $this->isGranted('EDIT') &&
$this->hasRoute('delete') && $this->isGranted('DELETE')
) {
$actions['merge'] = array(
'label' => 'action_merge',
'translation_domain' => 'SonataAdminBundle',
'ask_confirmation' => true
);
}
return $actions;
}
}
And there is nothing in my table "etudiant_notification".

Please make the following changes (bold lines) to your code:
Notification.php
/**
* Add etudiant
*
* #param \App\BlogBundle\Entity\Etudiant $etudiant
* #return Notification
*/
public function addEtudiant(\App\BlogBundle\Entity\Etudiant $etudiant)
{
$etudiant->addNotification($this);
$this->etudiant[] = $etudiant;
return $this;
}
Etudiant.php
/**
* Add notification
*
* #param \App\BlogBundle\Entity\Notification $notification
* #return Etudiant
*/
public function addNotification(\App\BlogBundle\Entity\Notification $notification)
{
$notification->addEtudiant($this);
$this->notification[] = $notification;
return $this;
}
and check what happens. No guarantee, but you can give it a try. Bonne chance!
