Php Symfony2+条令关联错误：类游戏没有名为home的关联

以下是MySQL表的列和行：

我正在尝试使用Team.id内部加入game.home和game.away，但我得到了错误：error:Class Travel\Bundle\TravelBundle\Entity\game没有名为home的关联我做错了什么

以下是我想要实现的预期结果，我知道如何在MySQL中实现，但不知道Symfony和Doctrine：

select 
    t1.id as gameid, 
    t1.season as gameseason, 
    t1.gametype as gametype, 
        t2.id as homeid, 
        t2.name as homename, 
        t2.abbreviation as homeabbreviation, 
        t2.type as hometype, 
        t2.image as homeimage,
            t3.id as awayid, 
            t3.name as awayname, 
            t3.abbreviation as awayabbreviation, 
            t3.type as awaytype, 
            t3.image as awayimage from Game t1 
            INNER JOIN Team t2 on t1.home  = t2.id
            INNER JOIN Team t3 on t1.away  = t3.id;

以下是我的原则实体：

Game.orm.yml：

Team.orm.yml

GameRepository.php

根据您的映射，应该如下所示：

Game.orm.yml：

你不能有多个oneToOne条目，我的意思是字符串‘oneToOne’，正如你在这里所做的一样，我编辑了我的答案，所以请检查一个oneToOne条目与两个关系：home和away
