Django notification on comment submission

问题

I am making use of Django's contrib.comments and want to know the following.

Are there any utils or app out there that can be plugged into an app that sends you a notification when a comment is posted on an item?

I haven't really worked with signals that much, so please be a little bit descriptive.

This is what I came up with.

from django.contrib.comments.signals import comment_was_posted
from django.core.mail import send_mail

if "notification" in settings.INSTALLED_APPS:
    from notification import models as notification

def comment_notification(request):
    user = request.user
    message = "123"
    notification.send([user], "new comment", {'message': message,}) 

    comment_was_posted.connect(comment_notification)

回答1:

Connect django.contrib.comments.signals.comment_was_posted to notification.models.send() as appropriate.

You have to register your comment_notification function with comment_was_posted signal.

from django.contrib.comments.signals import comment_was_posted

if "notification" in settings.INSTALLED_APPS:
    from notification import models as notification

    def comment_notification(sender, comment, request):
        user = request.user
        message = "123"
        notification.send([user], "new comment", {'message': message,}) 

    comment_was_posted.connect(comment_notification)

I don't know of an app (pretty sure there'll be something out there) but it is fairly straightforward to roll your own. You can tap the Comment model's comment_was_posted signal to call a function that will send you an email.
