I think class django.contrib.syndication.feeds.Feed need
item_categories methods that allow use of categories also in high-level
syndication framework.
Something like this should work:
# ITEM CATEGORIES --One of the following three is optional. The
# framework looks for them in this order.
#
# If you specify this, you must specify item_categories.
def item_categories(self, obj):
"""
Takes an item, as returned by items(), and returns the item's
categories as a Python list.
"""
def item_categories(self):
"""
Returns the categories for every item in the feed.
"""
item_categories = ("Action", "Drama", "Sci-Fi",) # Hard-coded
categories.
