Couchdb-如何按日期和没有id字段的相反顺序获取结果

我正在测试一些Couchdb特性，我希望按插入日期、按I字段查询的相反顺序获得结果 示例文档：

   "date": "2014-05-05T15:52:42Z"
}

我的看法是：

function(doc) {
  if(doc.i && doc.date){
      emit([doc.i,doc.date],1); // 1 to test only
  }
}

我正在用以下方法进行测试：

myview?startkey=["3566120224"]&endkey=["3566120224",{}]&reversed=true

但我得到的数据的日期顺序没有颠倒

我有两次相同的数据日期&日期为[ms date]，1399305161，即=2014-05-05T15:52:42Z 我认为我可以使用更易于解析的couchdb数据类型对结果进行排序，但使用日期字段不起作用 此外，我不需要id字段，如何将其从结果中排除？

如果查看，您可以看到反向查询不是受支持的查询选项。要反转数据，请执行以下操作：

myview?endkey=["3566120224"]&startkey=["3566120224",{}]&descending=false

如果不需要ID字段，可以在最高分组级别返回减少的值：

myview?endkey=["3566120224"]&startkey=["3566120224",{}]&descending=false&group_level=2

要删除该文档，我只需编写：

    function(doc) {
      if(doc.i && doc.date){
        emit([doc.date],1); // just removed doc.i
     }
    }

要扭转结果，请执行以下操作：

您可以更改结果，以便使用降序选项。但我认为这是一种不好的做法，因为这取决于使用此功能的客户端。 假设这是视图的默认用法，我会选择以整数形式返回日期。Date.parsedoc.Date.valueof应该以整数或双精度返回历元时间。如果返回带有“-”的值，则默认情况下，视图将按降序排序。这是假设您不需要密钥中的格式化日期。
