我需要通过employeeId来计算工作时间的总和。我的意思是，对象3和5（下面的集合）属于同一个employeeId（63fefac1ce76e418acc00ee7）。我应该怎么做才能得到工作时间的数量？
我试着用 Mongoose 聚合物，但至今没有成功。

    clockIn: 2023-03-04T06:27:27.013Z,

  {

    employeeId: ObjectId("63fef8c7ce76e418acc00e98"),

    updatedAt: 2023-03-04T16:49:27.044Z,
    __v: 0
  },
  {
    _id: new ObjectId("64037df808650d277693f106"),
    clockIn: 2023-03-03T06:31:56.290Z,
    clockOut: 2023-03-03T15:03:58.632Z,
    employeeId: ObjectId("63fefac1ce76e418acc00ee7"),
    createdAt: 2023-03-04T17:20:56.302Z,
    updatedAt: 2023-03-04T17:20:58.633Z,
    __v: 0
  }`

这是我的Axios Get，但结果带来了每天的工作小时数，而不是根据需要对天数求和。

- 得到**

timesheetRouter.get('/timesheet/:clockIn/:clockOut/show', async (req, res) => {
  try {
    const clockInOutTimesheet = await Timesheet.find().populate('employeeId', 'name employeeCode department fulltime')
    return res.status(200).json(clockInOutTimesheet)
  } catch (error) {
    console.log(error)
    return res.status(500).json({message: "Error code 1001"})
  }
})

结果应该是这样的：

employeeId: 63feed3c60a04fbc61c52f91 ==> 4.03 hours
employeeId: 63feece460a04fbc61c52f89 ==> 8.08 hours
employeeId: 63fefac1ce76e418acc00ee7 ==> (7.98 + 8.03) = 16.01 hours
employeeId: 63fef8c7ce76e418acc00e98 ==> 8.73 hours

按热度按时间

需要将日期更改为ISODate
按empoyeeId和$sum平均值分组（分钟）
转换为小时

db.collection.aggregate([
  {
    $group: {
      _id: "$employeeId",
      averageTime: {
        $sum: {
          $avg: {
            $dateDiff: {
              startDate: {
                $dateFromString: {
                  dateString: "$clockIn",
                },
              },
              endDate: {
                $dateFromString: {
                  dateString: "$clockOut",
                },
              },
              unit: "minute",
            },
          },
        },
      },
    },
  },
  {
    $project: {
      hours: {
        $round: [
          {
            $divide: ["$averageTime", 60],
          },
          2,
        ],
      },
    },
  },
]);
