TypeError: 'CommandCursor' object is not subscriptable
我用的是pymongo 查询出来数据然后报这个错误
timer_object_id_list = TimerServer._get_collection().aggregate(
[{'$sort':{'timer_time':-1}},
{'$match':{'timer_status':'0'}},{"$group":{"_id":"$timer_object_id"}}])['result']
查询了消息发现查询出来的数据类型是commandcursor 不能带有['result']
于是去掉
timer_object_id_list = TimerServer._get_collection().aggregate(
[{'$sort':{'timer_time':-1}},
{'$match':{'timer_status':'0'}},{"$group":{"_id":"$timer_object_id"}}])
- 注意:后面的数组操作也要更换需要转换成list具体可以看pymongo的CommandCursor源码可以看看有哪些属性也可查询官网点击此处
