Question

如何在laravel eloquent raw方法中编写group by和count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中计算。

请检查下面的集合和代码。感谢

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这样

$bookings               = Booking::raw(function ($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
                            ],
                    ],
                ]);
            });

以下是带有count和group by的原始查询。

<强> Controller.php这样

$bookings               = Booking::raw(function ($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','status' => '$status'],
                                'count' => ['$sum' => 1]
                            ],
                    ],
                    [
                        '$project' =>
                            [
                                'checkin_from' => '$_id.checkin_from',
                                'cabinname' => '$_id.cabinname',
                                'status' => '$_id.status',
                                'count' => 1,
                            ],
                    ],
                    [
                        '$sort' =>
                            [
                                'checkin_from' => 1
                            ],
                    ],
                ]);
            });

如何在laravel eloquent raw方法中从mongo db collection中获取状态字段的数量？
