Doctrine2 - No foreign key inserted in the table with relation OneToMany( - php

Question

I have a problem with doctrine2 with a simple relationship between the two models
Below I have prepared a simple example
/**
* #Entity(repositoryClass="PlayerRepository") #Table(name="players")
*/
class Player {
/**
* #Id #Column(type="integer") #GeneratedValue
*/
protected $id;
/**
* #OneToMany(targetEntity="Wallet", mappedBy="player", cascade={"persist"})
* #var Wallet[]
*/
private $wallets;
public function __construct() {
$this->wallets = new ArrayCollection();
}
public function getId() {
return $this->id;
}
public function setId($id) {
$this->id = $id;
}
public function getWallets() {
return $this->wallets;
}
public function addWallets($wallets) {
$this->wallets[] = $wallets;
}
}
And second class
/**
* #Entity(repositoryClass="WalletRepository") #Table(name="wallets")
*/
class Wallet
{
/**
* #Id #Column(type="integer") #GeneratedValue
*/
protected $id;
/**
* #ManyToOne(targetEntity="Player", inversedBy="wallets")
*/
private $player;
public function getId() {
return $this->id;
}
public function setId($id) {
$this->id = $id;
}
public function getPlayer() {
return $this->player;
}
public function setPlayer($player) {
$this->player = $player;
}
}
For the following code execution, I am not able to add Player object relations to Wallet:
player = new Player();
$player->addWallets(new Wallet);
$player->addWallets(new Wallet);
$entityManager->persist($player);
$entityManager->flush();
Maybe it will be better seen in the attached picture:

As far as I know you have to set this on the owning site, in this case Wallet, give it a try:
$player = new Player();
$wallet = new Wallet();
$wallet->setPlayer($player);
$entityManager->persist($player);
$entityManager->persist($wallet);
$entityManager->flush();
