They can only visit the page if you provide an url it. Just don't make
any url that displays page without your counter
I don't think I understand what you want, since what I think you want is
super trivial. But...
def my_view(request):
counter = Counter.objects.get(id=someid)
counter.count += 1
counter.save()
# Or see
http://www.djangoproject.com/documentation/request_response/ if you want
to use different value/counter based on what page led them to current view.
# referer is unreliable
refer = request.META.get( "HTTP_REFERER", None)
counter = Counter.objects.get(refer=refer)
counter.count += 1
counter.save()
# do whatever to show view
Which is not a great way of doing it (db hit every page view, fails when
you start caching results) but those don't matter unless your site is
real busy.
another option parsing apache/nginx/whatever logs for whenever
particular url(s) where responded to.
