Symfony Howto創建一個實體並將其添加到另一個實體？

嗨，感謝您花時間閱讀本文。英語不是我的第一語言，所以我希望你能原諒我的任何錯誤。目前我正在做一個項目，以熟悉Symfony的3Symfony Howto創建一個實體並將其添加到另一個實體？

這就是我想要做的事：

我有一個一對多的關係，遊戲以PlayLog。該關係已建立，我可以在我的遊戲中查看日期列表。

我想創建一個新的PlayLog並與遊戲相關聯，以便通過遊戲訪問我所有的相關PlayLogs。視圖顯示與遊戲的ID（log.html.twig）

我的問題： 如何創建一個新的PlayLog與表單和日期formField（dateType），並將其添加到現有的遊戲？

更新：與當前的代碼，我現在得到這個錯誤：

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

這是我的代碼：

我已經想通了，我試圖堅持只有一個ID（$ gameId），但它期望整個遊戲對象。 （1）所以我首先要獲得實際存儲庫對象的ID之後，我能堅持這個對象：

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(),

與您的代碼我得到這個錯誤：在執行「INSERT INTO play_log發生異常（date，game_id）VALUES（？，？）'with params [「2017-03-04」，null]： SQLSTATE [23000]：完整性約束違規：1048'game_id'列不能爲空 – Ducky

我認爲這與您的PlayLog實體有關。刪除所有方法和$ game_id屬性，並用cli命令重建方法：bin/console doctrine：generate：entities AppBundle：PlayLog並且當然也更新數據庫模式：bin/console doctrine：schema：update --force –

啊，我非常接近：$ playlog-> getGameId（）現在返回一個ID，這意味着我可以訪問它。我更新了我的代碼 – Ducky

Symfony Howto創建一個實體並將其添加到另一個實體？
