我有兩個實體User和UserProfile。 UserProfile primaryKey值不是AUTO_INCREMENT,它是使用來自User的主鍵值的一對一關係。當我創建新的用戶我有一個錯誤:Doctrine2級聯實體創建
Entity of type App\PublicBundle\Entity\User\UserProfile is missing an assigned ID for field 'user'. The identifier generation strategy for this entity requires the ID field to be populated before EntityManager#persist() is called. If you want automatically generated identifiers instead you need to adjust the metadata mapping accordingly.
問題是我如何能夠拯救實體下一個數據庫和實體的結構:
用戶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
)
用戶實體:
/**
* @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;
}
用戶配置實體:
/**
* @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;
}
註冊行動
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()
));
}
試圖保持兩個主鍵同步通常比它的價值更麻煩。特別是在使用諸如Doctrine 2之類的對象關係管理器時。只需要按照流程進行操作,併爲UserProfile指定它自己的數據庫ID。或者使用嵌入式值對象。 – Cerad
是的,我想過這個,但我想另一種更正確的方式是存在的 –
