Design pattern to handle anonymous users and event tracking using bitmapist.

generate_events.py

import bitmapist


ANONYMOUS_USER_KEY = 'anonymous_user'

def generate_event(event_name, user_id=None):
    if user_id is None:
        user_id = 'anon:%s' % bitmapist.get_redis().incr(ANONYMOUS_USER_KEY)
    bitmapist.mark_event(event_name, user_id)
