so it means when i call user[1] after user[0], it is possible that i
will get same record if someone else insert a new record into database
between 2 calls.

thank you.
then a basic python question.
how does queryset implement it?
does python also allow operator (e.g. []) overloading?

user = User.objects.filter(pk="")
user is a QuerySet
every time i call user[0], i returns a different reference.
maybe it should be a python question.
i want to know i QuerySet does that.

You received this message because you are subscribed to the Google Groups
"Django users" group.
To
users = User.objects.filter(pk=1)
user0 = user[0]
user1 = user[1]
user0 is user1
returns false
it seems [] returns different reference every time it is called?
how could this be done?
i know it's maybe a python question, if i post it in a wrong group,
i'm sorry.
