Django websub subscriber

Project description

Django websub subscriber.


pip install websubsub

Add websubsub.apps.WebsubsubConfig to the list of INSTALLED_APPS in your


Set the SITE_URL setting in your to the full url of your project site, e.g. It will be used to build full callback urls.

Set WEBSUBS_REDIS_URL settings in your Redis locks are used to ensure subscription/unsubscription tasks are consistent with hub and local database.

WEBSUBS_REDIS_URL = 'redis://redishost:6379'

Add websubsub.tasks.refresh_subscriptions and websubsub.tasks.retry_failed to celerybeat schedule. If you define it in

    'websub_refresh': {
        'task': 'websubsub.tasks.refresh_subscriptions',
        'schedule': 3600  # Hourly
    'websub_retry': {
        'task': 'websubsub.tasks.retry_failed',
        'schedule': 600  # Every 10 minutes


Create Websub callback

Create celery task handler, usually in

from celery import shared_task

def news_task(data):
    print('got news!')

Callback url should end with uuid. Register url for handler in

from websubsub.views import WssView
from .tasks import news_task, reports_task

urlpatterns = [
    path('/websubcallback/news/<uuid:id>', WssView.as_view(news_task), name='webnews')
    path('/websubcallback/reports/<uuid:id>', WssView.as_view(reports_task), name='webreports')


You can create subscription on the go, or use static subscriptions.

To create subscription in the code:

from websubsub.models import Subscription
Subscription.create(topic='mytopic', urlname='webnews', hub='')

This will create Subscription object in the database and schedule celery task to subscribe with hub.

Static subscriptions

[TODO] Not sure it is the best way to handle static subscriptions.

Static subscriptions can be defined in your, they are then materialized with management command ./ websubscribe_static.

Add static subscriptions in your

    '': {
        'subscriptions': [
            # (topic, urlname) pairs
            ('mytopic', 'webnews'),

Execute ./ websubscribe_static


To unsubscribe existing subscription, call Subscription.unsubscribe() method:

from websubsub.models import Subscription


Not implemented


SITE_URL - ex.: Required. Will be used to build full callback urls.

WEBSUBS_REDIS_URL - ex.: redis://redishost:6379. Required. Will be used to lock atomic tasks.





WEBSUBS_VERIFY_WAIT_TIME - How many seconds should pass before unverified subscription is considered failed. After that time, websubsub.tasks.retry_failed() task will be able to retry subscription process again.
