Use consistent indentations of one tab, or four spaces, per indent. Apart from anything else it makes your code much easier to read.

Look at line 16, and the lines immediate above and below it:
Python
def detail(request, question_id):
   try:
     question = Question.objects.get(pk=question_id)
    except Question.DoesNotExist:
Indentation in Python is critical: all code with exactly the same whitespace at the left is part of the same block: any change in whitespace ends the block and starts a new one.
So the first line in the try is a block on it's own, and the system cannot work out what to do with the subsequent lines at all.
