如何在laravel中显示2个表中id为的用户名

public function orders()
{
    return $this->hasMany(Order::class, 'user_id');
}

public function user()
{
    return $this->belongsTo(User::class, 'user_id');
}

public function showOrders()
{
    $orders = Order::with('user')->get();

    return view('orders', compact('orders'));
}

@foreach ($orders as $order)
    <p>订单号: {{ $order->order_number }}</p>
    <p>用户名: {{ $order->user->name }}</p>
@endforeach
