Hello guys, after doing a query with F() (see http://docs.djangoproject.com/en/dev/topics/db/queries/#query-expressions), I save the object, but then, I need to save it again.

The algorithm is simple: Y Combinator's Hacker News: Popularity = (p - 1) / ...

When the object is saved, it simply returns to the same template: if form.is_valid(): form.save() retur...
