    }
}

class Order extends Model
{

    }
}

use App\User;

class UserController extends Controller

    {
        $users = User::with('orders')->get();

        return view('users.index', compact('users'));
    }

@foreach ($users as $user)
    <h2>{{ $user->name }}</h2>
    <ul>
        @foreach ($user->orders as $order)
