Use RedirectView in urlpatterns (needed for Django 1.5)

'django.views.generic.simple.redirect_to' is not supported in Django 1.5

Use RedirectView.as_view instead.

The existing code was already importing RedirectView but still using the old 'django.views.generic.simple.redirect_to' in the url patterns.
