I'm heeding Adrian's call for m-r doc nitpicks.

My Python is pretty basic, but in the section of the m-r tutorial04.txt where the vote() function is defined, the code has this:

def vote(request, poll_id):
    selected_choice = p.choice_set.filter(pk=request.POST['choice'])
    selected_choice.votes += 1

The pk= lookup returns a selected_choice that is a <class 'django.db.models.query.QuerySet'>, but that particular creature has no attribute votes to be incremented by the code a few lines further down, so it throws an AttributeError exception. I'm sure it's just a minor tweak of how you talk to the QuerySet class, but that is black magic that's way beyond me.

FWIW, I was able to poke around and find the votes attibute in the list returned by doing a ...


... but that's too ugly to be believed. So, anyways, I think there may be a problem here (but I could be wrong).

it should be p.choice_set.get(pk=request.POST['choice'])
