This is a very simple way of getting authenticated RSS feeds in django, by slightly changing the django.contrib.syndication.views

1) copy django/contrib/syndication/views.py into mysite/feeds/views.py

2) replace the contents of that file with the snippet

3) any feeds which you require login just add them to the auth_required list. In this case I require login for /feeds/mystuff/ so I make auth_required = ['mystuff']

My directory structure is like this:

mysite/feeds/

views.py

feedmodels.py

feedmodels.py is just where you make your feed models (see http://docs.djangoproject.com/en/dev/ref/contrib/syndication/ where they give an example of "LatestEntries")

[urls.py] - this is what I add in urls.py

from mysite.feeds.feedmodels import Latest,MyPersonalStuff

feeds = {

'latest':Latest,

'mystuff':MyPersonalStuff,

}

(r'^feeds/(?P<url>.*)/$', 'mysite.feeds.views.feed', {'feed_dict': feeds}),
