我对Symfony很新。
作为用户，我只想看到我创建的实体。 用户可以登录并创建游戏，但我只想看到我创建的游戏实体。 它是用户和游戏的ManyToMany关系，其中User是拥有者。
示例：游戏＆＃34;游戏用户Joop1＆＃34;只能由用户查看 Joop1。标题为游戏的游戏＃34;游戏为Joop2＆＃34;可能只能被观看 Joop2。
如果将Joop1记录为当前用户，我怎么才能显示他用DQL / querybuilder创建的游戏？
我使用FOSUserBundle。
更新：我已将关系更改为： 用户 - ＆gt;游戏：多对多。
问题：这个sql语句的dql / querybuilder脚本是什么：
SELECT * FROM game,users_games WHERE users_games.user_id = 1
这是我目前基于Manuel DUVERNON回答的查询构建器脚本：
$em = $this->getDoctrine()->getManager();
$qb = $em->getRepository( Game::class )->createQueryBuilder( 'game_t' );
$qb->join( 'users_games.user_id', 'ug' )
->where( 'ug.user_id = :userId' )
->setParameter( 'userId', 1);
return $qb->getQuery()->getResult();
但这不起作用，因为我收到以下错误：
[语义错误]第0行，第70行附近＆＃39; .user_id ug WHERE＆＃39;：错误： 标识变量users_games用于连接路径表达式但是 以前没有定义过。

您可以获取当前登录的用户，然后使用 用户ID 请求您的dql查询。
看看：
$usr= $this->getUser();
$id=$usr->getId();
$em=$this->getDoctrine()->getManager();
$dql="SELECT * games FROM Game WHERE Game.user_id := user_id";
$query = $em->createQuery($dql);
$query->setParameter('user_id',$id);
$current_games = $query->getResult();
