Ok, I tried it and it works.
The idea is to put a cookie in the computer of the other person, where
it stocks all the polls it has participated to. That way it does not
depend of the IP.
The code:
def vote(request, poll_id):
p = get_object_or_404(Poll, pk=poll_id)
voted_polls=request.session.get('has_voted_poll',[])
if poll_id in voted_polls:
return render_to_response('sysvortex/polls/poll_results.html', {
'object': p,
'error_message': "You have already voted.",
})
if p.is_open == False :
# Display the poll results.
return render_to_response('sysvortex/polls/poll_results.html', {
'object': p,
'error_message': "The poll is closed.",
})
try:
selected_choice = p.choice_set.get(pk=request.POST['choice'])
except (KeyError, Choice.DoesNotExist):
# Redisplay the poll voting form.
return render_to_response('sysvortex/polls/poll_detail.html', {
'object': p,
'error_message': "You didn't select a choice.",
})
else:
selected_choice.votes += 1
selected_choice.save()
request.session['has_voted_poll']=voted_polls+[poll_id]
# 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('/polls/%s/results/' % p.id)
Any comment and improvement welcomed.
Enjoy,
