This is django-salmon, a drop-in Django application that adds support for the Salmon Protocol.
It doesn't work yet. Stay tuned though!
To use django-salmon, add it to your INSTALLED_APPS in settings.py: :
INSTALLED_APPS = (
...
'django_salmon',
...
)You will need models to represent feeds and comments. Set up signals for your feed model: :
import django_salmon
...
def salmon_subscriber(sender, **kwargs):
feed = kwargs.get('instance', None)
if not feed:
return
django_salmon.subscribe(feed, feed.url)
post_save.connect(salmon_subscriber, sender=Feed)
def salmon_unsubscriber(sender, **kwargs):
feed = kwargs.get('instance', None)
if not feed:
return
django_salmon.unsubscribe(feed)
post_delete.connect(salmon_unsubscriber, sender=Feed)Set up the following signal for your comment model: :
import django_salmon
from django_salmon.feeds import create_entry_feed
def comment_handler(sender, **kwargs):
comment = kwargs.get('instance', None)
if not comment:
return
try:
user = User.objects.get(username=comment.user_name)
except User.DoesNotExist:
return
url = 'https://%s%s' % (
Site.objects.get_current(),
comment.get_absolute_url())
parent = comment.content_object
feed = create_entry_feed(comment.comment, url, comment.comment,
author_name=comment.user_name,
author_link='acct:' + comment.user_email,
pubdate=comment.submit_date,
parent_id=parent.entry_id)
django_salmon.slap(feed, parent.feed, user)
post_save.connect(comment_handler, sender=Comment)Finally, in order to process salmon slaps, you must add a handler function to settings.py: :
SALMON_SLAP_HANDLER = 'comments.salmon_handler'This function will receive two parameters: the actual salmon and the mime_type (currently always application/atom+xml until support for other formats is added). It is the responsibility of this handler function to discover what content the salmon is associated with (in the case of mentions or replies) and handle accordingly.
** NOTE: ** This is a work in progress and at the moment only supports a very specific protocol flow with limited kinds of data.
