如何在 laravel 中动态排序列表？

Question

我尝试让待办事项列表能够通过过滤器对列表进行排序，这样我就可以获得今天的列表、明天的列表或本周的列表，所以我让我的任务控制器能够接受请求等通过设计模式存储库，我接受了做雄辩的请求：

控制器任务：

class TaskController extends Controller
{

    private $taskRepository;

    public function __construct(TaskRepository $taskRepository)
    {
        $this->taskRepository = $taskRepository;
    }

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(Request $request)
    {

        if(!empty($request)){
            // dd($request);
            $tasks = $this->taskRepository->all($request);

        }else{
            $tasks = $this->taskRepository->all();
        }

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

任务库：

class TaskRepository implements RepositoryInterface
{
    // model property on class instances
    protected $task;

     // Constructor to bind model to repo
     public function __construct(Task $task)
     {
         $this->task = $task;
     }

    public function all(Request $request)
    {
        $sortBy = 'expired_at';
        $order = Carbon::now();
        $finish = null;


        if($request)
        {
            if($request->has('today'))
            {
                $order = Carbon::today();
                return Task::where($sortBy, $order)->get();
            }

            if($request->has('tomorow')){

                $order = Carbon::tomorrow();
                return Task::where($sortBy, $order)->get();
            }

            if($request->has('week'))
            {

                $order = Carbon::now()->startOfWeek();
                $finish = Carbon::now()->endOfWeek();
                return Task::whereBetween($sortBy, [$order, $finish])->get();

            }


        }else{

            return Task::orderBy('order')->get();
        }
    }

为了完成我的索引，我使用“get”方法完成了表单：

div>

        <form action="{{ route('tasks.index') }}" class="flex justify-between items-center p-2">
                <div>

                    <select name="orderByDate" id="">
                        @foreach(['today','tomorow', 'week'] as $orderDate)
                            <option value="{{ $orderDate }}">{{ ucfirst($orderDate) }}</option>
                        @endforeach
                    </select>
                </div>

                <div>
                    <button type="submit">Filter</button>
                </div>
        </form>

</div>
<ul class="my-5">
    @foreach ($tasks as $task)

        @if($task->order == 0)

        <li class="flex text-red-600 justify-between p-2">
            // task->name
            // task-> date
            // task-> edit
            // task->delete
        </li>
        @else

            <li class="flex justify-between items-center p-2">
                // task->name
              // task-> date
              // task-> edit
              // task->delete
            </li>

        @endif
        @empty
            <p>Pas de tâches aujourd'hui crée en une</p>
        @endforelse
</ul>

@endsection

aparrently 我的 foreach 不适用于数组，所以如果有人知道我应该如何解决这个问题，这将是一个活生生的救星？

试试这个代码库功能

public function all(Request $request)
{
    $sortBy = 'expired_at';
    $order = Carbon::now();
    $finish = null;


    if($request)
    {
        if($request->has('today'))
        {
            $order = Carbon::today();
            return Task::query()->where($sortBy, $order)->orderBy($sortBy)->get();
        }

        if($request->has('tomorow')){

            $order = Carbon::tomorrow();
            return Task::query()->where($sortBy, $order)->orderBy($sortBy)->get();
        }

        if($request->has('week'))
        {

            $order = Carbon::now()->startOfWeek();
            $finish = Carbon::now()->endOfWeek();
            return Task::query()->whereBetween($sortBy, [$order, $finish])->orderBy($sortBy)->get();

        }


    }else{

        return Task::query()->orderBy($sortBy)->get();
    }
}
