No. Http404 is a special class, in that it's a subclass of Exception. If
you want to raise an exception to provide some kind of early bailout,
you'll need to either capture and handle those exceptions in each view
or write a middleware to handle the view exceptions (and don't catch the
exception).
My preferred method is to catch and handle any exceptions in the view,
since it makes it clear which layer is responsible for talking to the
server. However, I intentionally don't use things like get_object_or_404
in anything other than the outer view for the same reason: that code can
be reused without assuming it's going to be an HTTP response.
