laravel - 如何验证 Laravel 请求中的选择

Question

我正在构建一个应用程序来创建足球比赛。当我创建比赛时，我需要检查所选球队是否属于所选联赛。

提交表单后，我想显示一条消息，表明选择了错误的联赛。

Controller 中有store()方法

$match = new Match;
$match->round = $request->round;
$match->league_id = $request->league;
$match->home_team_id = $request->home_team;
$match->away_team_id = $request->away_team;
$match->match_date = $request->match_date;
$match->location = $request->location;

团队模型:

class Team extends Model
{
    public function league() {
        return $this->belongsTo('App\League');
    }
}

联赛模式:

class League extends Model
{
    public function teams() {
        return $this->hasMany('App\Team');
    }
}
