Write your own 404 handler or change the QR view behaviour by overwriting the get_object function.

class QRView(DetailView):
    def get_object(self, queryset=None):
        """
        Returns the object the view is displaying.

        By default this requires `self.queryset` and a `pk` or `slug` argument
        in the URLconf, but subclasses can override this to return any object.
        """
        # Use a custom queryset if provided; this is required for subclasses
        # like DateDetailView
        if queryset is None:
            queryset = self.get_queryset()

        # Next, try looking up by primary key.
        pk = self.kwargs.get(self.pk_url_kwarg, None)
        slug = self.kwargs.get(self.slug_url_kwarg, None)
        if pk is not None:
            queryset = queryset.filter(pk=pk)

        # Next, try looking up by slug.
        elif slug is not None:
            slug_field = self.get_slug_field()
            queryset = queryset.filter(**{slug_field: slug})

        # If none of those are defined, it's an error.
        else:
            raise AttributeError(u"Generic detail view %s must be called with "
                                 u"either an object pk or a slug."
                                 % self.__class__.__name__)

        try:
            obj = queryset.get()
        except ObjectDoesNotExist:
            # REDIRECT GOES HERE.
        return obj
