mysql - RedBeanPHP 多个 FK 到同一个表

Question

我正在使用最新版本的 RedBeanPHP。我正在对足球比赛结构进行建模。一场比赛由 2 支球队进行，属于一个比赛日(数据库中的赛程)。

$o = R::dispense('game');
$o->l = R::load('team',$l[$i]);
$o->v = R::load('team',$v[$i]);
$o->fixture = R::load('fixture',$id);
$id = R::store($o);

在数据库中，RB创建2个Fk:

• index_foreignkey_game_team
• index_foreignkey_game_fixture

插入游戏后，此代码不起作用:

$games = R::find('games',"fixture_id='$ID'");
foreach( $games as $o ):
    echo $o->l->id; // Cannot access to the Local Team
    echo $o->v->id; // Cannot access to the Visit Team
endforeach

谢谢!

Answer 1

只需使用别名来告诉 RedBeanPHP 'v' 和 'l' 是什么。

方法如下:

//for testing only...
list($team1, $team2) = R::dispense('team', 2);

$game = R::dispense('game');
$game->team = R::load('team',$team1);
$game->visitor = R::load('team',$team2);
$id = R::store($game);
$theGame = R::load('game', $id);


echo 'team1: '.$theGame->team->id;
echo PHP_EOL;
//here I tell RedBeanPHP: visitor IS a team.
echo 'team2: '.$theGame->fetchAs('team')->visitor->id;

希望这有帮助!
