django-infopush 1.8

Django reusable app, what allows to send web push.

django_infopush is a Django reusable app, that allows to gather push subscriptions and send web push notifications to browsers.

It is a full featured reusable app which includes:

• frontend & backend code which gathers push subscriptions and saves them to DB,

• service worker to show notifications, manage clicks and basic notification statistics,

• django admin interface where you create new push tasks (title, text, icon, url, image, time to send) and view stats for the old ones,

• django management command to perform your tasks (send notifications to subscribers).

This app covers 99% webpush needs for content web-sites than you just want to send an announcement of a new blog post for example. Just make a new push task in the admin and job is done.

Known limitations:

• You better have access to CRON on your server, because push tasks are send using python manage.py pushsend management command. And running it manually every time sounds like a bad idea. Although for testing purposes manual calls will do well.

Quick start

1. pip install django-infopush

2. Add “django.contrib.humanize” (if not in INSTALLED_APPS already) and “commonstuff”, “push” to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       # ...
       'django.contrib.humanize',
       'commonstuff',
       'push',
   ]

3. Enable sites framework in Django, see official docs.

4. Configure django_infopush in your project settings.py file. At least your DJANGO_INFOPUSH_VAPID_PUBLIC_KEY and DJANGO_INFOPUSH_VAPID_PRIVATE_KEY (you can simply generate them here).

   You also have to set DJANGO_INFOPUSH_VAPID_ADMIN_EMAIL with your site admin or support address, so that push-server administration can reach you if something goes wrong.

   E.g.:

   DJANGO_INFOPUSH_VAPID_PUBLIC_KEY = 'AHf42JhrMtFOXAG2OYTmEoBvKNcEsxmYF5pqvYd4InFEEU0x41HzymPQRtcvJZp9iNpDQK4GuTGMWAgn0E8G8IZ'
   DJANGO_INFOPUSH_VAPID_PRIVATE_KEY = 'CcmbGJ9wce7596DoObRzyPHNktPRo5CSCdericz7Pf7'
   DJANGO_INFOPUSH_VAPID_ADMIN_EMAIL = '[e-mail]'

   See docs/SETTINGS.rst for more.

5. If project uses MySQL, make sure it’s version is 5.7.7 or greater and add the following line to project’s settings.py:

   SILENCED_SYSTEM_CHECKS = ['mysql.E001']

   See docs/MYSQL.rst for details.

6. Run python manage.py migrate to create push models.

7. Include URLconf in your project urls.py like this:

   from django.conf.urls import url, include
   from django.conf import settings
   from django.views.generic import TemplateView
   from django.views.decorators.cache import cache_page
   
   urlpatterns = [
       # ...
       url(r'^push/', include('push.urls')),
       url(r'^service-worker.js$', cache_page(1 if settings.DEBUG else 86400)(TemplateView.as_view(
           template_name="push/service-worker.js",
           content_type='application/javascript; charset='+settings.DEFAULT_CHARSET,
       )), name='service-worker.js'),
   ]

8. Add {% include ‘push/_head_include.html’ %} into head-section of your django-project’s html template(s). Do not include it on the pages where you don’t want to see push-subscribe browser window. Visit your website to become first subscriber (currently Chrome and FF support webpush, not Safari).

9. Visit http://127.0.0.1:8000/admin/push/ to create first push task.

10. CRON setup for python manage.py pushsend management command (every 5-10 minutes). You can also run this command manually for testing purposes.

11. (OPTIONAL) Run python manage.py test push for basic check of the app.
