Comment (by James Addison): Adding this hack to the `Item` model addresses the issue for now. Yes, I realize this is overriding an undocumented, internal Django `Model` method and is thus fragile to future changes - but it's a hack that lets me proceed for now and hopefully helps the Django team. {{{ class Item(models.Model): .... def _do_update(self, base_qs, *args, **kwargs): qs = base_qs.all() qs.query.annotations.clear() return super()._do_update(qs, *args, **kwargs) }}} -- Ticket URL: <https://code.djangoproject.com/ticket/28838#comment:1> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
