一个表里存了三个外键该怎么关联？

class Goods extends Model
{
    public function city()
    {
        return $this->belongsTo(City::class,'city_id','goods_id');
    }
    public function goodsInfo()
    {
        return $this->belongsTo(GoodsInfo::class,'goods_info_id','goods_id');
    }
}

class GoodsController extends Controller
{
    public function Index(Goods $goods)
    {
        $goods->with(['city','goods_info'])->get();
    }
}
