Django, redirect all non-authenticated users to landing page

Question

I have a django website with many urls and views. Now I have asked to redirect all non-authenticated users to a certain landing page. So, all views must check if user.is_a

Answer 1

see the docs for login required decorator

from django.contrib.auth.decorators import login_required

@login_required
def my_view(request):
    ...

another option is to add it to your urls.py patterns, see this answer

urlpatterns = patterns('',
    (r'^foo/$', login_required(direct_to_template), {'template': 'foo_index.html'}),
)
