Django middleware that prevents multiple concurrent logins

django-preventconcurrentlogins

Django middleware that prevents multiple concurrent logins. If a user is already logged into the Django application and tries to log in somewhere else, the previous session is deleted.

This package is based on code from http://stackoverflow.com/a/1814797 and https://gist.github.com/peterdemin/5829440.

Usage

1. Add "preventconcurrentlogins" to your INSTALLED_APPS settings like this::

       INSTALLED_APPS = {        
           ...
               'preventconcurrentlogins',
       }

2. Add "preventconcurrentlogins.middleware.PreventConcurrentLoginsMiddleware" to MIDDLEWARE_CLASSES::

       MIDDLEWARE_CLASSES = {        
           ...
               'preventconcurrentlogins.middleware.PreventConcurrentLoginsMiddleware',
       }

3. Run python manage.py migrate to create the visitor model that is used to track a users currently active session key.
