Stream-framework требует django?

Question

Я изучаю стрим-фреймворк. Я выполнил руководство и создал базовую ленту, как показано ниже.

from stream_framework.feeds.redis import RedisFeed

    class PinFeed(RedisFeed):
        key_format = 'feed:normal:%(user_id)s'

    class UserPinFeed(PinFeed):
        key_format = 'feed:user:%(user_id)s'


feed = UserPinFeed(13)

Я получил ошибку ниже

`Traceback (most recent call last):

    objects = getattr(module, '__all__', dir(module))

During handling of the above exception, another exception occurred:

1. Как мне исправить эту ошибку?
2. Требуется ли для stream-framework django?
3. Учебник по Stream-framework трудно понять, так как я новичок. Есть ли учебник, в котором код построчно объясняется?
4. Есть ли хорошая альтернатива stream-framework, которую я могу использовать для ленты социальных сетей?
