Comment:
I am re-opening this, as I think the decision here ought to be revisited.
It reflects poorly on Django for the tutorial to teach poor coding
practices, particularly when there is a race condition in a vote-tallying
app. More and more, such race conditions are being treated as true
security vulnerabilities.
Following
[http://www.reddit.com/r/programming/comments/33zg4u/race_conditions_on_facebook_digitalocean_and/cqpxnpp
discussion on reddit], I suggest putting a note in the tutorial mentioning
that the code indeed has a race condition, and that more advanced users
should consider Django's F-expressions instead.
