Question

I want to show various messages to registered users only once in my django application. I found django-announcements which seemed to do what I want - but I found in testing it marks messages as read by using a session variable, which disappears if the user logs out. This means a message is shown again to a user if they dismiss it when logged in, log out, and then log in again.

I wondered if anyone know of an application that I might be able to use here without re-inventing the wheel.

Answer 1

Have a look at django-notification. It is used by pinax, there it seems to work like what you are searching for. At least it saves the status in the db.

Response to the comment

from the docs:

notification.send([to_user], "friends_invite", {"from_user": from_user})

so this should work:

notification.send(Users.objects.all(), "friends_invite", {"from_user": from_user})

and if a queryset isnt right:

notification.send([u for u in Users.objects.all()], "friends_invite", {"from_user": from_user})

Answer 2

Have you looked at the Messages Framework in Django 1.3? In Django <=1.2 it was a simple model so you could do:

for user in User.objects.all():
    user.message_set.create(message="some text")

and this would be rendered in the template, and dismissed as soon as the next page is loaded (it s what Django admin uses). It has changed a bit in 1.3, but it might be handy, but not dismissable in the way that maybe you want.
