Django:How can I prevent authenticated user from both register and login page in Django-registration-redux

HomeCategory: stackoverflowDjango:How can I prevent authenticated user from both register and login page in Django-registration-redux
rupesh asked 3 weeks ago

I am currently using Django-registration-redux for my authentication system.
Already logged in user can visit the login and registration page again; which is not good enough. How can I prevent them from this since the views.py comes by default in Django-registration-redux
I think that should be done in the views.py that come with Django-registration-redux

Here is the views.py

"""
