Question

The example provides a snippet for an application level view, but what if I have lots of different (and some non-application) entries in my “urls.py” file, including templates? How can I apply this login_required decorator to each of them?

(r'^foo/(?P<slug>[-\w]+)/$', 'bugs.views.bug_detail'),
(r'^$', 'django.views.generic.simple.direct_to_template', {'template':'homepage.html'}),

Dropped this into a middleware.py file in my project root (taken from http://onecreativeblog.com/post/59051248/django-login-required-middleware)

from django.http import HttpResponseRedirect
from django.conf import settings
from re import compile

EXEMPT_URLS = [compile(settings.LOGIN_URL.lstrip('/'))]
if hasattr(settings, 'LOGIN_EXEMPT_URLS'):
    EXEMPT_URLS += [compile(expr) for expr in settings.LOGIN_EXEMPT_URLS]

class LoginRequiredMiddleware:
    """
    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.
    """
    def process_request(self, request):
        assert hasattr(request, 'user'), "The Login Required middleware\
 requires authentication middleware to be installed. Edit your\
 MIDDLEWARE_CLASSES setting to insert\
 'django.contrib.auth.middlware.AuthenticationMiddleware'. If that doesn't\
 work, ensure your TEMPLATE_CONTEXT_PROCESSORS setting includes\
 'django.core.context_processors.auth'."
        if not request.user.is_authenticated():
            path = request.path_info.lstrip('/')
            if not any(m.match(path) for m in EXEMPT_URLS):
                return HttpResponseRedirect(settings.LOGIN_URL)

Then appended projectname.middleware.LoginRequiredMiddleware to my MIDDLEWARE_CLASSES in settings.py.
