Eloquent 与多列的关系

Question

所以我有以下 match table，其中包含参加那场比赛的球队的号码。我想与看起来像这样的 teams 建立关系：

团队Table

| id | number |  name   |  etc  |
| 1  |  1234  | Example |  etc  |
| 2  |  2345  | Example |  etc  |

etc...

匹配 Table

| id |  match  |  red1  | red2 | blue1 | blue2 |
| 1  |    1    |  1234  | 1710 |  673  | 2643  |
| 2  |    2    |  2345  | 1677 | 4366  | 246   |

etc...

我想要 $this->match->where("match", "=", "2")->first()->teams();。

我试过使用 hasMany() 但我似乎无法使用 red1, red2, blue1, blue3 列。

我尝试过的：

class Matches extends Model
{
    protected $table = "match_table";

    protected $fillable = [
        "match_id",
        "time",
        "bluescore",
        "redscore",
        "red1",
        "red2",
        "red3",
        "blue1",
        "blue2",
        "blue3",
    ];

    public function teams()
    {
        return $this->hasMany("App\Models\Teams", "number", ["red1", "red2", "blue1", "blue2"]);
    }
}

我最后做的只是遍历我想要的每一列，然后返回一个新的 Collection 和其中的结果。

public function teams()
{
    $result = [];

    foreach($this::$teamColumns as $column) {
        $result[] = $this->hasMany("App\Models\Teams", "number", $column)->first();
    }

    return new Collection($result);
}
