我有两张桌子: 拥有id,group_id和name的团队 具有id,home_team_id,away_team_id,日期和分数的游戏
正如您在我的游戏表中看到的那样,有两个外键(home_team_id和away_team_id)指向同一个表(团队)。 如何用laravel雄辩的方式映射这些关系? 我试过了,但失败了:
namespace App;
use Illuminate\Database\Eloquent\Model;
class Team extends Model
{
public function group(){
return $this->belongsTo('App\Group');
}
public function games(){
return $this->hasMany('App\Game');
}
}
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Game extends Model
{
public function homeTeam(){
$this->belongsTo('App\Team', 'home_team_id');
}
public function awayTeam(){
$this->belongsTo('App\Team', 'away_team_id');
}
public function bets(){
$this->hasMany('App\Bet');
}
}
在我看来,我想打电话给home_team-&gt; name和away_team-&gt; name:
<td>{{ $game->homeTeam->name }}</td>
<td>{{ $game->awayTeam->name }}</td>
我收到此错误: 关系方法必须返回类型为Illuminate \ Database \ Eloquent \ Relations \ Relation
的对象和
关系方法必须返回Illuminate \ Database \ Eloquent \ Relations \ Relation类型的对象(查看:/home/vagrant/Code/em/resources/views/schedule/index.blade.php)
答案 0 :(得分:2)
您需要从方法中返回关系。例如:
return $this->belongsTo('App\Team', 'home_team_id');
您在团队模型中执行此操作,但不是游戏模型。
