Question:

This is the signup view:

def signup(request, form_class=SignupForm,          template_name="account/signup.html", success_url=None):      if success_url is None:          success_url = get_default_redirect(request)      if request.method == "POST":          form = form_class(request.POST)          if form.is_valid():              username, password = form.save()              if settings.ACCOUNT_EMAIL_VERIFICATION:                  return render_to_response("account/verification_sent.html", {                      "email": form.cleaned_data["email"],                  }, context_instance=RequestContext(request))              else:                  user = authenticate(username=username, password=password)                  auth_login(request, user)                  request.user.message_set.create(                      message=_("Successfully logged in as %(username)s.") % {                      'username': user.username                  })                  return HttpResponseRedirect(success_url)      else:          form = form_class()      return render_to_response(template_name, {          "form": form,      }, context_instance=RequestContext(request))
