Getting exception when trying to generate feed

I am trying to generate a feed.
So I added the following lines to urls.py

feeds = {'latest': main_feed}
urlpatterns += patterns('',
      (r'^rss/(?P<url>.*)/$',
'django.contrib.syndication.views.feed',
{'feed_dict': feeds})
      )

The class main_feed is,

def main_feed (Feed):
    blog = Blog.objects.all()[0]
    title = blog.title
    link = "/rss/latest/"
    description = blog.description
    def items (self):
       entries = BlogEntry.entry.all()[:blog.recents * 2]
       return entries

Now I should be getting the feed at /rss/latest/ , but I am
getting an
error like
TypeError at /rss/latest/
main_feed() takes exactly 1 argument (2 given)

Full error stack,
Traceback:

That should be:

class main_feed(Feed):
