Question

下面的代码是从mongoDB获取数据，并在日期范围(sum(prepayment_amount) and sum(total_prepayment_amount) group by checkin_from date)中绘制图表中金额和日期的总和。金额总和在y axis，日期在x axis。

从这段代码我得到金额和日期的总和，但问题是，

查看日期和时间2017-10-05T19:07:17Z & 2017-10-05T00:00:00Z。在这种情况下（sum(prepayment_amount)和sum(total_prepayment_amount)日期分别绘制。

如果日期和时间为2017-10-05T00:07:17Z & 2017-10-05T00:00:00Z。我得到了正确的结果。

我不知道问题出在哪里。我添加了例外结果。任何帮助，将不胜感激。感谢

请检查图像，在这里你可以找到问题。为了更好地理解，我已经在x轴上列出了时间。

Note:In graph data not match with question data because I have connected database with test server.

Answer 1

在$group中您直接使用$checkin_from作为时间日期，因此按日期和时间进行分组。

答案是使用$dateFormat，所以我们只有没有时间的日期：

'_id' => ['checkin_from' => ['$dateFormat' => ['date' => '$checkin_from', format => '%Y-%m-%d']], 'cabinname' => '$cabinname']

Answer 2

您可以使用此组雄鹿，我将字符串转换为数字。根据提供的数据，total_prepayment_amount和prepayment_amount是字符串它们应为$sum的整数。

  [
    '$group' =>[
      '_id' => [
          'checkin_from' => '$checkin_from',
          'cabinname' => '$cabinname'
       ],
      'total_prepayment_amount' => [
           '$sum' => ['$toInt' => '$total_prepayment_amount']
       ],
      'prepayment_amount' => [
         '$sum' => ['$toInt' => '$prepayment_amount']
       ],
    ],
  ],

在查询mongodb时喜欢这样

total_prepayment_amount: {$sum : { $toInt: "$total_prepayment_amount"}},

请确保 mongodb ^ 4.0 （用于$ toInt）
