Question

我有像

这样的文件

{"title":"title_1","website":"website_1","isEdited":"true"},
{"title":"title_2","website":"website_1","isEdited":"true"},
{"title":"title_3","website":"website_2"},
{"title":"title_4","website":"website_3","isEdited":"false"}

所以文件有＆＃34; isEdited＆＃34;具有多个值的字段（None，true，flase）我想计算它们的所有出现次数并将它们分组为

{'_id' : '$website','edited_count': '?', 'not_edited_count': '?'}

而不是上面我能够得到这个

{u＆＃39; isEditedCount＆＃39;：2，你＆＃39; _id＆＃39;：你＆＃39; website_1＆＃39;}

使用此管道

[
  {"$match": {"isEdited": 'true'}},
  {"$group": {"_id": "$website", "isEditedCount": {"$sum": 1}}}
]

和 [ {u＆＃39; isNotEditedCount＆＃39;：1，你＆＃39; _id＆＃39;：u＆＃39; website_2＆＃39;}， {u＆＃39; isNotEditedCount＆＃39;：1，你＆＃39; _id＆＃39;：你＆＃39; website_3＆＃39;} ]

使用此管道

[
  {"$match":{"$or":[{"isEdited": None},{"isEdited": 'false'}]}},
  {"$group":{"_id": "$website","isNotEditedCount": {"$sum": 1}}}
]

我想将两个管道合并为一个

如何匹配单个字段与两个不同的值并在mongoDB聚合python中计算匹配的文件？
