Something like Facebook and that.
Anyone knows?.
Directly in Django? Generally speaking, no. (It can be done, but by using a polling mechanism which doesn’t really scale well.)
Using Django Channels, yes. (In fact, it’s what you create when you work through the Django Channels tutorial.)
In either case, there would also be some JavaScript involved as well.
Oh…
Ok. Thanks for answering anyways! 
Oh btw
Do you know where can I have tutorials of the framework?
A very simple one can be created using a pushpin server in front of the Django application. The client listens via server-send event, and when a message is written, it sends it via POST.
It’s quite easy to create a basic one, lacking security, but it demonstrates that it can be done.
