PuSH is the other name of PubSubHubbub, a publish/subscribe protocol based on HTTP and allowing near-instant notifications of topic updates.

  • Publishers are entities that publish their updates via HTTP resources. When a resource is updated with a new entry, they ping their hub saying they have some new content. The hub is also declared in the resource.
  • Subscribers are feed readers or followers. When they fetch a resource, they notice a hub is declared and subscribe to the resource’s updates with the hub.
  • Hubs fetch the published resource when it gets a ping from the publisher and takes care of notifying all the subscribers.

This library provides hooks to add PubSubHubbub support to your Django project: you can use it to be a publisher and/or subscriber.

The PubSubHubbub spec was initially designed for Atom feeds. The 0.3 version of the spec defines resources as feeds. The 0.4 version allows arbitrary content types. The 0.4 spec is supported since version 0.5 of django-push. We unfortunately missed the chance of having version numbers match properly.

    • Drop support for Python 3.2.
    • Confirm support for Django 1.10.

    • Use a transaction hook in Subscription.objects.subscribe() when available (Django 1.9+).
  • 0.7 (2015-07-10):

    • Remove warnings with Django versions up to 1.8.
  • 0.6.1 (2014-01-14):

    • Added PUSH_TIMEOUT setting for passing timeouts to the subscribe/unsubscribe HTTP calls.
  • 0.6 (2013-07-10):

    • Removed get_hub().
    • Removed the unsubscribe() manager method. Unsubscribing must be done with subscription instances.
    • Added request and links keyword arguments to the updated signal. request is the raw HTTP request object, links is a parsed version of the Link header, if present.
  • 0.5 (2013-06-24):

    • Python 3 support, Django >= 1.4.1 support.

    • HTTP handling via requests instead of urllib2.

    • Deprecation of Subscription.objects.unsubscribe() in favor of an instance method on the subscription object. The unsubscribe() manager method will be removed in version 0.6.

    • Subscription.objects.subscribe() raises a warning if the hub kwarg is not provided. It will become mandatory in version 0.6.

    • Removed hub.verify_token from subscription requests. It’s optional in the 0.3 spec and absent from the 0.4 spec.

    • Secret generation code uses django.utils.crypto instead of the random module. In addition, subscriptions over HTTP don’t use a secret anymore (as recommended in the spec).

    • The updated signal is sent with the raw payload instead of the result of a feedparser.parse call. This allows other content types than feeds to be processed, as suggested in version 0.4 of the PubSubHubbub spec.

    • The callback view is now a class-based view, allowing listening for content distribution via a custom view if the updated signal is not suitable.

    • django.contrib.sites is no longer a hard requirement. You can set PUSH_DOMAIN in your settings to your site’s canonical hostname.

    • South migrations support. If you don’t use South, you should. If you’re upgrading from 0.4, just fake the first migration and apply the others:

      ./ migrate subscriber 0001_initial --fake
      ./ migrate
    • Tremendously improved admin support. If you were using a custom ModelAdmin for subscriptions, you might want to try the built-in one.

  • 0.4 (2011-06-30):

    • Support for hub authentication via PUSH_HUB_CREDENTIALS.
    • Support for SSL callback URLs.
  • 0.3 (2010-08-18):
