Django - Custom decorator involving processing the request

gistfile1.py

# Django provides some great and easy to use decorators 
# that accept simple functions that you could use to 
# perform certain tests on the user. However, if your test 
# depends on some parameter within the request object (like mine did), 
# you could do something like:


from django.contrib.auth import REDIRECT_FIELD_NAME
from django.utils.decorators import available_attrs
from django.utils.http import urlquote
from django.http import HttpResponseRedirect
from functools import wraps

def my_test_func(request):
    # Do some foobar
    return True     # or False

def is_super_user():
    def user_is_admin(redirect_field_name = REDIRECT_FIELD_NAME):
        from django.conf import settings
        login_url = settings.LOGIN_URL
        def decorator(view_func):
        # You can do any pre processing here before control 
        # is handed over to the view
            def _wrapped_view(request, *args, **kwargs):
                test = my_test_func(request) # Returns true or false
                if test:    # if user passes test
                    return view_func(request, *args, **kwargs)
                path = urlquote(request.get_full_path())
                tup = login_url, redirect_field_name, path
                return HttpResponseRedirect('%s?%s=%s' % tup)
            return wraps(
                view_func, 
                assigned = available_attrs(view_func))(_wrapped_view)
        return decorator
    return user_is_admin()


# Usage in views.py - User cannot see the dashboard unless he passes the test.

@is_super_user()
def dashboard(request):
  return render_to_response('dashboard.html', {'msg': 'Hello world'})
