Is there a way to negate a boolean returned to variable?

Solution 1:

You can do this:

item.active = not item.active

That should do the trick :)

I think you want

item.active = not item.active

item.active = not item.active is the pythonic way

Another (less ~~concise~~ readable, more arithmetic) way to do it would be:

item.active = bool(1 - item.active)

The negation for booleans is not.

def toggle_active(item_id):
    item = Item.objects.get(id=item_id)
    item.active = not item.active
    item.save()

Thanks guys, that was a lightning fast response!
