    Middleware that requires a user to be authenticated to view any page other
    than LOGIN_URL. Exemptions to this requirement can optionally be specified
    in settings via a list of regular expressions in LOGIN_EXEMPT_URLS (which
    you can copy from your urls.py).

    Requires authentication middleware and template context processors to be
    loaded. You'll get an error if they aren't.
    
    Based on https://djangosnippets.org/snippets/1179/
    My modification adds 'next' GET parameter to enable redirection after
    successful login.

Hello, thanks for posting this. I am getting TypeError: object() takes no parameters. If I remove this class from the Middleware array, it works fine.

Any Ideas?

I think you are using django 1.10, there is a little modification to be done for django 1.10

Import the MiddlewareMixin from django.utils.deprecation. Modify the LoginRequiredMiddleware class to inherit from the MiddlewareMixin.
