Doctrine2-沒有在表中插入具有OneToMany關系的外鍵（

Question

我對doctrine2有問題，兩個模型之間存在簡單關系下面我准備了一個簡單示例

/**
 * @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;
}
}

第二等

/**
 * @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;
}
}

對於以下代碼執行，我無法將Player對象關系添加到Wallet：

player = new Player();
$player->addWallets(new Wallet);
$player->addWallets(new Wallet);
$entityManager->persist($player);
$entityManager->flush();

也許在所附圖片中會更好看：

據我所知，您必須在所有者站點 （在本例中為Wallet ，試試看：

$player = new Player();

$wallet = new Wallet();
$wallet->setPlayer($player);

$entityManager->persist($player);
$entityManager->persist($wallet);

$entityManager->flush();
