Description

Reusable application for Django introducing a message delivery framework.

Features:

• Message Types - message classes exposing message composition logic (plain text, html, etc.).
• Messengers - clients for various protocols (smtp, jabber, twitter, telegram, facebook, vkontakte, etc.);
• Support for user defined message types.
• Support for user defined messenger types.
• Message prioritization.
• Message subscription/unsubscription system.
• Message grouping to prevent flooding.
• Message 'read' indication.
• Means for background message delivery and cleanup.
• Means to debug integration: test requisites, delivery log.
• Django Admin integration.

1. Configure messengers for your project (create sitemessages.py in one of your apps):

from sitemessage.toolbox import register_messenger_objects, register_message_types
from sitemessage.messengers.smtp import SMTPMessenger

register_messenger_objects(
    # Here we register one messenger to deliver emails.
    # By default it uses mailing related settings from Django settings file.
    SMTPMessenger()
)

2. Schedule messages for delivery when and where needed (e.g. in a view):

from sitemessage.shortcuts import schedule_email

def send_mail_view(request):
    ...

    # Suppose `user_model` is a recipient Django User model instance.
    user1_model = ...

    # We pass `request.user` into `sender` to keep track of senders.
    schedule_email('Message from sitemessage.', [user1_model, 'user2@host.com'], sender=request.user)

    ...

3. Periodically run Django management command from wherever you like (cli, cron, Celery, uWSGI, etc.):

   ./manage.py sitemessage_send_scheduled

And that's only the tip of sitemessage iceberg, read the docs %)
