Can someone spot something that could possibly cause a runtime error ? This
the Poll example from the djangoproject homepage. Any help is appreciated.
*views.py: *
from django.http import HttpResponse, HttpResponseRedirect
from django.shortcuts import render, get_object_or_404
from django.core.urlresolvers import reverse
from polls.models import Poll, Choice
def index(request):
latest_poll_list = Poll.objects.all().order_by('-pub_date')[:5]
context = {'latest_poll_list': latest_poll_list}
return render(request, 'polls/index.html', context)
def detail(request, poll_id):
poll = get_object_or_404(Poll, pk=poll_id)
return render(request, 'polls/detail.html', {'poll':poll})
def results(request, poll_id):
poll = get_object_or_404(Poll, pk=poll_id)
return render(request, 'polls/results.html', {'poll': poll})
def vote(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
try:
selected_choice = p.choice_set.get(pk=request.POST['choice'])
except (KeyError, Choice.DoesNotExist):
# Redisplay the poll voting form.
return render(request, 'polls/detail.html', {
'poll': p,
'error_message': "You didn't select a choice.",
})
else:
selected_choice.votes += 1
selected_choice.save()
# Always return an HttpResponseRedirect after successfully dealing
# with POST data. This prevents data from being posted twice if a
# user hits the Back button.
return HttpResponseRedirect(reverse('polls:results', args=(p.id,)))
