Avitab,
Whitespace is very important to Python.
You added an extra tab to your else and else clause of your try expression.
Consider the error message: unindent does not match outer indentation level
The message is mentioning indents, so let’s check our indents for any problems.
try:
selected_choice =
question.choice_set.get(pk=request.POST['choice'])
except (KeyError, Choice.DoesNotExist):
#Redisplay the question voting form.
return render(request, 'polls/detail.html',
{
'question': question,
'error_message': "you didn't
select a choice.",
})
else:
selected_choice.votes +=1
selected_choice.save()
#...
#...
#...
return
HttpResponseRedirect(reverse('polls:results', args=(question.id,)))
