If you are stuck on django 1.2 like I am and RedirectView doesn't exist, another route-centric way to add the redirect mapping is using:
(r'^match_rules/$', 'django.views.generic.simple.redirect_to', {'url': '/new_url'}),
You can also re-route everything on a match. This is useful when changing the folder of an app but wanting to preserve bookmarks:
(r'^match_folder/(?P<path>.*)', 'django.views.generic.simple.redirect_to', {'url': '/new_folder/%(path)s'}),
This is preferable to django.shortcuts.redirect if you are only trying to modify your url routing and do not have access to .htaccess, etc (I'm on Appengine and app.yaml doesn't allow url redirection at that level like an .htaccess).
