Yes and no. Django allows you to define signals, one of them being a post_save signal on a Model. It has no mechanism to notify "User B", as it does not know how to notify User B. But, it has views and urls and browsers have Ajax. So you can poll (not realtime). Django Channels (which is a 3rd party package created by one of Django's core developers) supports websockets. Using websockets one can notify in (near) real time. So in order to do what you want, you need to glue signals to channels, or teach Django Channels how to detect a change in your model. -- Melvyn Sopacua -- You received this message because you are subscribed to the Google Groups "Django users" group.
