Doctrine2级联实体创建

我有两个实体User和UserProfile。UserProfile primaryKey值不是AUTO_INCREMENT，它是使用User中的主键值的一个关系。当我创建新用户时，我有一个错误：

App''PublicBundle''Entity''User''UserProfile类型的实体缺少为字段"User"分配的ID。此实体的标识符生成策略要求在调用EntityManager#persist（）之前填充ID字段。如果您想要自动生成标识符，则需要相应地调整元数据映射。

问题是如何使用下一个数据库和实体结构保存实体：

用户DDL:

CREATE TABLE `user` (
  `intUserID` int(10) unsigned NOT NULL AUTO_INCREMENT,
  PRIMARY KEY (`intUserID`),
)
CREATE TABLE `user_profile` (
  `intUserID` int(10) unsigned NOT NULL,
  PRIMARY KEY (`intUserID`),
  CONSTRAINT `user_profile_ibfk_1` FOREIGN KEY (`intUserID`) REFERENCES `user` (`intUserID`) ON DELETE CASCADE ON UPDATE CASCADE
)

用户实体：

/**
 * @ORM'Table(name="user")
 * @ORM'Entity
 */
class User
{
    /**
     * @var integer
     *
     * @ORM'Id
     * @ORM'Column(name="intUserID", type="integer", nullable=false)
     * @ORM'GeneratedValue(strategy="IDENTITY")
     */
    protected $intuserid;
    /**
     * @var 'App'PublicBundle'Entity'User'UserProfile
     *
     * @ORM'OneToOne(targetEntity="'App'PublicBundle'Entity'User'UserProfile",
     *      mappedBy="user",
     *      cascade={"persist", "remove"}
     * )
     */
    protected $profile;
}

UserProfile实体：

/**
 * @ORM'Table(name="user_profile")
 * @ORM'Entity
 */
class UserProfile
{
    /**
     * @var 'App'PublicBundle'Entity'User'User
     *
     * @ORM'Id
     * @ORM'OneToOne(targetEntity="'App'PublicBundle'Entity'User'User",
     *      inversedBy="profile"
     * )
     * @ORM'JoinColumns({
     *   @ORM'JoinColumn(name="intUserID", referencedColumnName="intUserID")
     * })
     */
    protected $user;
}

注册操作

private function registration(Request $request, $tpl)
{
    $user = new User();
    $form = $this->$form($user, 'Create');
    $form->handleRequest($request);
    if ('POST' === $request->getMethod())
    {
        if ($form->isValid())
        {
            $em->getConnection()->beginTransaction();
            try
            {
                $em = $this->getManager();
                $em->persist($user);
                $em->flush();
                $this->sendSuccessEmail($user);
                $em->getConnection()->commit();
            }
            catch ('Exception $e)
            {
                $em->getConnection()->rollback();
                throw $e;
            }
            return $this->redirect($this->generateUrl('app_profile'));
        }
    }
    return $this->render($tpl, array(
        'entity' => $user,
        'form' => $form->createView()
    ));
}
