嗨，谢谢你花时间阅读本文。 英语不是我的第一语言，所以我希望你能帮我找错。 目前我正在做一个熟悉Symfony 3的项目。
这就是我想要做的事情：
我有一个OneToMany关系，Game to PlayLog。 建立关系，我可以查看我的游戏中的日期列表。
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。 显示的视图带有游戏ID（log.html.twig）
我的问题： 如何使用表单和日期formField（dateType）创建一个新的PlayLog，并将其添加到现有游戏中？
更新：使用当前代码我现在收到此错误：
执行＆＃39; INSERT INTO play_log时发生异常（日期， game_id）VALUES（？，？）＆＃39;与params [＆＃34; 2017-03-04＆＃34;，null]： SQLSTATE [23000]：完整性约束违规：1048列＆＃39; game_id＆＃39; 不能为空
这是我的代码：

不确定这是否是您要找的答案..
您可以在Playlog控制器中稍微调整newAction和他的Route注释，以便在路径中添加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(),
));
}

我已经弄清楚了，我试图坚持只有一个ID（$ gameId），但它期待整个Game对象。 （1）所以我首先必须使用ID获取实际的存储库对象，之后我可以保留此对象：
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(),
));
}
