【问题描述】：

如何在 laravel eloquent raw 方法中编写分组和统计状态？我正在使用 mongodb。

出于测试目的，我使用 mysql 进行了计数（结果和查询在下面给出），但我不知道如何在 mongodb 中进行计数。

请检查下面给出的集合和代码。谢谢

SQL

SELECT count(*), status, date FROM booking WHERE date BETWEEN '2017-08-01' AND '2017-08-31' group by status, date order by date

结果

count status date 3 1 2017-08-01 1 2 2017-08-01 2 2 2017-08-02 1 3 2017-08-02 1 1 2017-08-03 1 2 2017-08-03 1 1 2017-08-04 1 2 2017-08-04 1 3 2017-08-04 1 3 2017-08-05 2 2 2017-08-06 2 3 2017-08-07 1 1 2017-08-08 1 2 2017-08-08 1 3 2017-08-08 1 1 2017-08-09 1 2 2017-08-09

Controller.php

$bookings               = Booking::raw(function ($collection) use ($cabinName, $dateBegin, $dateEnd) {
                return $collection->aggregate([
                    [
                        '$match' => [
                            'is_delete' => 0,
                            'cabinname' => $cabinName,
                            'checkin_from' => ['$gte' => $dateBegin, '$lte' => $dateEnd]
                        ],
                    ],
                    [
                        '$group' =>
                            [
                                '_id' => ['checkin_from' => '$checkin_from','cabinname' => '$cabinname'],

                            ],
                    ],
                    [
                        '$project' =>
                            [
                                'checkin_from' => '$_id.checkin_from',
                                'cabinname' => '$_id.cabinname',

                            ],
                    ],
                    [
                        '$sort' =>
                            [
                                'checkin_from' => 1
                            ],
                    ],
                ]);
            });

【解决方案1】：

这是带有计数和分组依据的原始查询。

Controller.php

$bookings               = Booking::raw(function ($collection) use ($cabinName, $dateBegin, $dateEnd) {
                return $collection->aggregate([
                    [
                        '$match' => [
                            'is_delete' => 0,
                            'cabinname' => $cabinName,
                            'checkin_from' => ['$gte' => $dateBegin, '$lte' => $dateEnd]
                        ],

                                'count' => ['$sum' => 1]
                            ],
