Question

I’m building a project with Django, and am currently trying to implement django-notification as a means to keep track of user activity. While I managed to install it and create some notifications, they are only sent via email but not stored in the respective databases so that I could display them in a feed view.

The /notifications/feed/ currently gives me a type error, I’m not sure if that is related?

TypeError at /notifications/feed/
init() takes exactly 3 arguments (1 given)

Any advice would be kindly appreciated. I’ve looked at how Pinax uses notification, but couldn’t figure out how they got beyond the email-only backend.

In settings.py I have ‘notification’ enabled, as well as the template_context_processor ‘notification.context_processors.notification’.

urls.py

    url(r'^note/', include('notification.urls')),

app/management.py

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

def create_notice_types(app, created_models, verbosity, **kwargs):
    notification.create_notice_type("messages_received", _("Message Received"), _("you have received a message"), default=2)

signals.post_syncdb.connect(create_notice_types, sender=notification)

app/view.py

...      
if notification:
    notification.send([user], "messages_received", {'message': message,})
...

notification.send is executed, I checked this, but it seems that nothing is stored in the “notice” database ..

I should add, I’m running the Brian Rosner branch of django-notification (https://github.com/brosner/django-notification).

Answer 1

It appears that brosner’s fork of django-notifications differs from jtauber’s in that send_now() does not actually add Notice instances to the database, nor does the default EmailBackend notification backend.

You will have to write your own notification backend class that creates a Notice instance when deliver() is called, and add it to NOTIIFICATION_BACKENDS.

An (untested) example replicating jtauber’s behavior:

class MyBackend(BaseBackend):
    def deliver(self, recepient, sender, notice_type, extra_context):
        messages = self.get_formatted_messages(["notice.html"],
            notice_type.label, extra_context)
        notice = Notice.objects.create(recipient=recepient,  
            message=messages['notice.html'], notice_type=notice_type, 
            on_site=on_site, sender=sender)
        notice.save()
