Adopted Spec Format

Subscribing

Subscription.objects.subscribe(user, content_object) # Subscribes a user

Emitting

Just one person, but not if its the author of the comment

Subscription.objects.to(comment_obj.content_object.user).not_to(comment_obj.user).emit("comment.create", comment_spec)

All subscribers of the content objects except the author of the comment

Subscription.objects.of(comment_obj).not_to(comment_obj.user).emit(
    "comment.create", comment_obj,
    emitter_class=ModelEmitter)

Settings

The args/kwargs to emit() are more or less shuttled straight to the SUBSCRIPTION_BACKEND(s), which is a dict in your settings.py like:

SUBSCRIPTION_BACKENDS = {
  'email': 'myproject.subscription_backends.Email',
  'redis': 'myproject.subscription_backends.Redis',
}

SUBSCRIPTION_ACTSTREAM_PROPERTIES = [
   'contentOwner'
]
# Use this if you wanna say fuckit to the 'official' activitystream properties

Writing a backend

You can subclass subscription.backends.BaseBackend. Right now the options are:

SomeBackend.emit(recipient, 'some.verb', **activity_stream_spec_plus_whatever)

• recipient (auth.User)
• verb
• activity stream spec attrs (published, target, object, actor)
• **kwargs - Passed onto your backend subclass in case you need more info
