You're doing some very odd things here. You're putting the queryset into a
list and then putting that list into a set: so that when you iterate
through the set, what you actually get is the queryset as one object, not
the individual objects within it.
You could fix this by just doing
obj_all=set(attendance.objects.all())
- ie without the surrounding [] - but it's not clear why you think you need
a set in the first place. A queryset will never give you duplicate objects,
because it's a simple representation of the db query, which can't itself
have duplicates. You might have duplicate *data* within the table, but that
won't be de-duplicated by the set(), as the rows themselves are still
unique.
