Different type of anonymous users with Django -

the django project i'm working on website should accessed local network , internet. , part of content should available anonymous users if visit site local network (basically it's test on ip address), while authenticated users have access whole content.

i though checking ip as described here, seems me quite bad check ip each time user loads page.

is there way cleanly store user data on anonymous user ? nice able use decorator @login_required, redirect if anonymous user has external ip.

actually, checking ip on every requests seems me 1 of fastest methods available. consider ip loaded in memory on every request, have simple dictionary lookup , comparison, conditional string split/additional dict lookup. compared happens on simplest page views, performance impact neglectable , comparable impact of using sessions or other mechanism save ip.

you can write own decorator function using user_passes_test:

from django.contrib.auth.decorators import user_passes_test django.utils.decorators import available_attrs functools import wraps  local_ips = (     '127.0.0.1',     'other_ip',     'etc.', )  def is_local_request(request):     x_forwarded_for = request.meta.get('http_x_forwarded_for')     if x_forwarded_for:         ip = x_forwarded_for.split(',')[0]     else:         ip = request.meta.get('remote_addr')     return ip in local_ips  def local_ip_required(view_func):     def wrapped_view(request, *args, **kwargs):         if not is_local_request(request):             raise http404 # or permissiondenied or redirect         return view_func(request, *args, **kwargs)     return wraps(view_func, assigned=available_attrs(view_func))(wrapped_view) 

then use @local_ip_required. note implementation prevent both anonymous , logged-in users accessing view external location.
