[Solved]-How to use django-notification to inform a user when somebody comments on their post


Yes django-notifications is only designed for email notifications.

Here is a signal slot that you can add to your models.py and tweak to your own needs:

from django.db import models
from django.contrib.sites.models import Site
from django.db.models import signals
from notification import models as notification

def create_notice_types(app, created_models, verbosity, **kwargs):
    notification.create_notice_type("new_comment", "Comment posted", "A comment has been posted")
signals.post_syncdb.connect(create_notice_types, sender=notification)

def new_comment(sender, instance, created, **kwargs):
    # remove this if-block if you want notifications for comment edit too
    if not created:
        return None

    context = {
        'comment': instance,
        'site': Site.objects.get_current(),
    recipients = []

    # add all users who commented the same object to recipients
    for comment in instance.__class__.objects.for_model(instance.content_object):
        if comment.user not in recipients and comment.user != instance.user:

    # if the commented object is a user then notify him as well
    if isinstance(instance.content_object, models.get_model('auth', 'User')):
        # if he his the one who posts the comment then don't add him to recipients
        if instance.content_object != instance.user and instance.content_object not in recipients:

    notification.send(recipients, 'new_comment', context)

signals.post_save.connect(new_comment, sender=models.get_model('comments', 'Comment'))

Now for templates, pretty easy.


{{ comment.user }} commented on {{ comment.object }}


<a href="{{ comment.user.get_absolute_url }}">{{ comment.user }}</a> commented <a href="{{ comment.content_object.get_absolute_url }}">{{ comment.content_object }}</a>


{{ comment.user }} commented on {{ comment.content_object }}

{{ comment.comment }}

Reply on: 
http://{{ site.domain }}{{ comment.content_object.get_absolute_url }}

Warning: it’s a very simplified, untested adaptation of our production code.

Note : Django-1.7 deprecated the post_syncdb signal
