why I cannot use such sentense:
s=People.objects.filter(Position='A')
s.comment_set.all()
The django says that the queryset does not have the attribution
comment_set.Why?
Not sure why you needed to post this question three times.
`s` is a queryset, composing a number of People objects. So it doesn't
itself have a comment_set attribute - neither does it have Schoolnum
or Gender. It's the *members* of the s queryset that have these
atttributes.
