Django:How can I ensure that a view can only be directed from another view

Question

I have two views

def view1(request):
    do something
    return HttpResponseRedirect(reverse(view2), args1)

Now I need view2 to only work if it's referred by view1. How do I do that? I did read it somewhere, not able to recollect

@somefilter
def view2(request):
    do something
    #view2 will only be referred from view1, else Http404

I think you should check for the HTTP_REFERER HTTP header. See the documentation. Here is a Django snippet that gives you a decorator to check for referrers.
