Symfony3.4 persist of oneTomany entity - symfony-3.4

Question

i need to make a chat for one application in symfony3.4, so i created a channel entity and a message entity, i made a One to Many relations and a i add message in the channel but there is no persistent of the entity include in the intentity.
In Message Entity
/* $channel.
*
* (Many-To-One, Unidirectional)
* #ORM\ManyToOne(targetEntity="Soraya\ChatBundle\Entity\chanEntity",inversedBy="messages")
* #ORM\JoinColumn(name="channel_id", referencedColumnName="id")
*
*/
protected $channel;
public function setChannel(\Soraya\ChatBundle\Entity\chanEntity $channel ){
$this->channel = $channel;
return $this;
}
In ChanEntity Entity
/*
* $messages
* (One-To-Many, Bidirectional)
* #ORM\OneToMany(targetEntity="Soraya\ChatBundle\Messages", mappedBy="channel"),cascade={"persist", "remove"})
*
*
*/
protected $messages;
public function __construct() {
parent::__construct();
$this->messages = new ArrayCollection();
}
public function addmessages(\Soraya\ChatBundle\Entity\Messages $message){
$this->messages[]=$message;
$message->setChannel($this);
return $this;
}
In my controller
`public function addMessageAction(Request $request, $idChan, $utilisateur, $message){
$em = $this->getDoctrine()->getManager();
//message
$advertmess = new Messages();
$advertmess->setMessage($message);
$advertmess->setpseudoUtilisateur($utilisateur);
// chan
$advert2 = $em->getRepository('ChatBundle:chanEntity')->find($idChan);
$advert2->addmessages($advertmess);
// entity
$em->persist($advert2);
$em->persist($advertmess);
$em->flush();
//$em->persist($advert);
//$em->flush();
var_dump($advert2);
//var_dump($advertmess);
return new Response("OK");
}`
When i saw the var_dump in the request i can see the entity inside the entity but when i try to access to it after there nothing :
Exemple of what i can see in var_dump of chan
object(Soraya\ChatBundle\Entity\chanEntity)[790]
protected 'messages' => null
protected 'typesChan' => string 'contact' (length=7)
.......
Exemple in request
object(Soraya\ChatBundle\Entity\chanEntity)[849]
protected 'messages' =>
array (size=1)
0 =>
object(Soraya\ChatBundle\Entity\Messages)[838]
protected 'pseudoUtilisateur' => string 'user' (length=16)
protected 'message' => string 'testword' (length=5)
protected 'channel' =>
&object(Soraya\ChatBundle\Entity\chanEntity)[849]
protected 'id' => int 135
protected 'sync_uuid' => string '64373958-f69e-4b84-8543-aa3ed6b3be19' (length=36)
protected 'isDeleted' => boolean false
protected 'cree_le' =
......
The entity inside my entity don't persist i can access to the message created in mydatabase but not in the connexion between chan and message. Someone get an idea of what could be wrong ? Thank you.

Answer 1

i find my mistake, there is need one more * in the ORM JOIN, it must be like that.
/** $channel.
*
* (Many-To-One, Unidirectional)
* #ORM\ManyToOne(targetEntity="Soraya\ChatBundle\Entity\chanEntity",inversedBy="messages")
* #ORM\JoinColumn(name="channel_id", referencedColumnName="id")
*
*/
protected $channel;
