问题 clicks = SellerClick.objects.extra({'date' : "date(timestamp)"}).values('date').annotate(count=Count('timestamp')) The model has a datetime field called timestamp that was are using. I first, convert the datetime field to just a date field. Then the rest is guessing. I need to group by, and then count how many objects are of each date. So the desired result would be a date, then a count, based on how many objects have that date in the timestamp field. 回答1: I prefer to use annotate over extra
