Suggested new dispatch flow for class based views.

gistfile1.py

# @meshy's suggestion:
    def dispatch(self, request, *args, **kwargs):
        # Try to dispatch to the right method; if a method doesn't exist,
        # defer to the error handler. Also defer to the error handler if the
        # request method isn't on the approved list.
        if request.method.lower() in self.http_method_names:
            handler = getattr(self, request.method.lower(), self.http_method_not_allowed)
        else:
            handler = self.http_method_not_allowed
        self.prepare_view(request, handler, *args, **kwargs)
        return handler(request, *args, **kwargs)

    # Could probably do with a better name...
    def prepare_view(self, request, handler, *args, **kwargs):
        """Set local variables before the dispatch handler is called."""
        self.request = request
        self.args = args
        self.kwargs = kwargs
