As Alex says, we'll need to see the full view function to really help.
But assuming the last line what you've posted is actually the last
line of the function, you are indeed missing something - the code to
return something if the form fails validation.
The error message you've posted tells you exactly what's happening -
your view is not returning an HttpResponse. It's always your
responsibility to do this - Django won't ever do something by default
(except 404 and 500 errors). Look more closely at the example given in
the documentation:
http://docs.djangoproject.com/en/dev/topics/forms/#using-a-form-in-a-view
You'll see that in that view, the return at the end is called in both
the case of the initial GET, and if the POST failed validation.
