TypeError: 'CommandCursor' object is not subscriptable 問題解決

TypeError: 'CommandCursor' object is not subscriptable

我用的是pymongo 查詢出來數據然后報這個錯誤

timer_object_id_list = TimerServer._get_collection().aggregate(
                    [{'$sort':{'timer_time':-1}},
                     {'$match':{'timer_status':'0'}},{"$group":{"_id":"$timer_object_id"}}])['result']

查詢了消息發現查詢出來的數據類型是commandcursor 不能帶有['result']
於是去掉

timer_object_id_list = TimerServer._get_collection().aggregate(
                    [{'$sort':{'timer_time':-1}},
                     {'$match':{'timer_status':'0'}},{"$group":{"_id":"$timer_object_id"}}])

• 注意：后面的數組操作也要更換需要轉換成list具體可以看pymongo的CommandCursor源碼可以看看有哪些屬性也可查詢官網點擊此處
