There is not your problem, but maybe will be in future. The best way to clean fields that depend of other fields is override the clean method of form.

Oh, you are passing a URL to render() instead of a template name. Try something like this:

return render(request, 'signup.html', {'form': signup_form})

Sorry, didn't catch that the first time.
