Tutorial

So we want the pins, comments and follows to show up in the user's feed. We start by installing stream_django

pip install stream_django

add stream_django to your INSTALLED_APPS

INSTALLED_APPS = [
    ...
    'stream_django'
]

We indicate which models should be shared by using the Activity mixin.

class Pin(Activity, models.Model):
    ...

Now when users will add a pin it will automatically show up on the user feed. However to setup the newsfeed we also need to know who follows who.

feed_manager.follow_user(user_id, target_id)

This is all that's needed to setup the newsfeed. To retrieve the newsfeed we use the following code

@login_required
def feed(request):
    '''
    Items pinned by the people you follow
    '''
    enricher = Enrich(request.user)
    context = RequestContext(request)
    feed = feed_manager.get_news_feeds(request.user.id)['flat']
    if request.REQUEST.get('delete'):
        feed.delete()
    activities = feed.get(limit=25)['results']
    context['activities'] = enricher.enrich_activities(activities)
    response = render_to_response('core/feed.html', context)
    return response

The last bit of work is making sure the templates render nicely.

{% for activity in activities %}
    {% render_activity activity %}
{% endfor %}

This will render the templates in
