从数据库中获取所有记录到 Laravel 中的特定月份

Question

在我的数据库中我有这个预订记录

App\Reservation {#2632
     id: 1,
     user_id: 7,
     rest_id: 23,
     reservation_date: "2019-08-29",
     from_time: "16:00:00",
     to_time: "00:00:00",
     count_of_people: 15,
     loyalty_points: 100,
     confirme: 2,
     cancle: 0,
     surveySended: 0,
     surveyAnswer: 0,
     created_at: null,
     updated_at: null,
   },

在我的控制器中，我有这段代码试图检索本月的所有预订：

public function getRestAdmin(Request $request,$rest_id)
{

$restaurant=Restaurant::find($rest_id);
  $today=\Carbon\Carbon::today();
//reservations made this month
$reservations=$restaurant->reservations()->where('confirme',2)->whereBetween('reservation_date',[$today->startOfMonth(),$today->endOfMonth()])->get();
 }

但我总是得到 null!!

Answer 1

假设您在数据库中对这些日期进行了预订，请尝试让 Carbon 直接在查询之前完成繁重的工作（无需先设置为今天）：

$start = new Carbon('first day of this month');
$end = new Carbon('last day of this month');

然后只需将变量添加到查询中：

whereBetween('reservation_date',[$start, $end]) ...

您也可以在 Carbon 上使用此方法：

$start = Carbon::now()->startOfMonth();

Answer 2

强制格式来自 Carbon

$reservations = $restaurant
    ->reservations()
    ->where('confirme',2)
    ->whereBetween('reservation_date',[
        $today->startOfMonth()->format('Y-m-d'),
        $today->endOfMonth()->format('Y-m-d')
    ])->get();
