Symfony 如何创建实体并将其添加到另一个实体？
Symfony Howto create a entity and add it to another?
您好，感谢您花时间阅读本文。
英语不是我的第一语言，所以我希望您能原谅我的任何错误。
目前我正在做一个项目来熟悉 Symfony 3。
这就是我想要做的：
我有一个 oneToMany 关系，Game 到 PlayLog。
关系已建立，我可以在我的游戏中查看日期列表。
我想创建一个新的 PlayLog 并与游戏相关联，这样我就可以通过游戏访问所有相关的 PlayLog。
显示带有游戏 ID 的视图 (log.html.twig)
我的问题：
如何使用表单和日期 formField(dateType) 创建新的 PlayLog，并将其添加到现有游戏中？
更新：使用当前代码我现在得到这个错误：
An exception occurred while executing 'INSERT INTO play_log (date,
game_id) VALUES (?, ?)' with params ["2017-03-04", null]:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'game_id'
cannot be null
这是我的代码：

不确定这是否是您要找的答案..
您可以稍微调整一下 Playlog 控制器中的 newAction 和他的 Route 注释，以便在路由中添加 gameId
/**
* Creates a new playLog entity.
*
* @Route("/{gameId}/new", name="playlog_new")
* @Method({"GET", "POST"})
*/
public function newAction(Request $request, $gameId)
{
$em = $this->getDoctrine()->getManager();
$game = $em->getRepository('AppBundle:Game')->find($gameId);
if(null === $game) {
throw $this->createNotFoundException('The game with id ' . $gameId . ' does not exist.');
}
$playLog = new Playlog();
$playLog->SetGame($game);
$form = $this->createForm('AppBundle\Form\PlayLogType', $playLog);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em->persist($playLog);
$em->flush($playLog);
return $this->redirectToRoute('playlog_show', array('id' => $playLog->getId()));
}
return $this->render('playlog/new.html.twig', array(
'playLog' => $playLog,
'form' => $form->createView(),
));
}
我已经弄明白了，我试图坚持只使用一个 ID ($gameId)，但它需要整个 Game 对象。 (1) 所以我首先必须使用 ID 获取实际的存储库对象，然后才能持久化该对象：
public function newAction(Request $request, $gameId)
{
$playlog = new PlayLog();
$em = $this->getDoctrine()->getManager();
// (1) Get Game object with given gameId:
$game = $em ->getRepository(Game::class)->find($gameId);
//Set the Game object
$playlog->setGame($game);
$form = $this->createForm('AppBundle\Form\PlayLogType', $playlog);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
/* @var $playLog PlayLog */
$playlog = $form->getData();
$em->persist($playlog);
$em->flush();
}
return $this->render('playlog/new.html.twig', array(
'playLog' => $playlog,
'form' => $form->createView(),
));
}

不确定这是否是您要找的答案..
您可以稍微调整一下 Playlog 控制器中的 newAction 和他的 Route 注释，以便在路由中添加 gameId
/**
* Creates a new playLog entity.
*
* @Route("/{gameId}/new", name="playlog_new")
* @Method({"GET", "POST"})
*/
public function newAction(Request $request, $gameId)
{
$em = $this->getDoctrine()->getManager();
$game = $em->getRepository('AppBundle:Game')->find($gameId);
if(null === $game) {
throw $this->createNotFoundException('The game with id ' . $gameId . ' does not exist.');
}
$playLog = new Playlog();
$playLog->SetGame($game);
$form = $this->createForm('AppBundle\Form\PlayLogType', $playLog);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em->persist($playLog);
$em->flush($playLog);
return $this->redirectToRoute('playlog_show', array('id' => $playLog->getId()));
}
return $this->render('playlog/new.html.twig', array(
'playLog' => $playLog,
'form' => $form->createView(),
));
}
我已经弄明白了，我试图坚持只使用一个 ID ($gameId)，但它需要整个 Game 对象。 (1) 所以我首先必须使用 ID 获取实际的存储库对象，然后才能持久化该对象：
public function newAction(Request $request, $gameId)
{
$playlog = new PlayLog();
$em = $this->getDoctrine()->getManager();
// (1) Get Game object with given gameId:
$game = $em ->getRepository(Game::class)->find($gameId);
//Set the Game object
$playlog->setGame($game);
$form = $this->createForm('AppBundle\Form\PlayLogType', $playlog);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
/* @var $playLog PlayLog */
$playlog = $form->getData();
$em->persist($playlog);
$em->flush();
}
return $this->render('playlog/new.html.twig', array(
'playLog' => $playlog,
'form' => $form->createView(),
));
}
