Django. How to return to the previous page?

Question

Django

I have a django controller image_delete. I use it on multiple pages. I need the controller to take me back to the previous page after deleting the image. But I am getting an error. what is the problem? How to fix it?
views.py

class ImageDelete(DeleteView):
    model = Picture 
    template_name = 'adminapp/pet/pet_image_delete.html'
    
    @method_decorator(user_passes_test(lambda x: x.is_superuser)) 
    def dispatch(self, *args, **kwargs): 
        return super().dispatch(*args, **kwargs)

    def get_success_url(self):
        return HttpResponseRedirect(request.META.get('HTTP_REFERER'))

If I prescribe "self" before "request", then I get the error "quote_from_bytes () expected bytes"
urls.py

path('delete/image/<int:pk>/', adminapp.ImageDelete.as_view(model=Picture), name='image_delete')

Screenshot error.

def get_success_url(self):should return the url and not the response. Just try

def get_success_url(self):
    return request.META.get('HTTP_REFERER')
