Doctrine2 -未在具有关系OneToMany的表中插入外键(

Question

我对下面两个模型之间的简单关系的doctrine2有一个问题，我准备了一个简单的示例

/**
 * @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;
}
}

和二等舱

/**
 * @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;
}
}

对于下面的代码执行，我无法将Player对象关系添加到Wallet：

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

也许在附加的图片中会更好地看到：

据我所知，您必须在owning site上设置此设置，在本例中为Wallet，试一试：

$player = new Player();

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

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

$entityManager->flush();
