Comment (by skorokithakis): I think that thinking about this in terms of the value of the ID field is misleading. The ID value being None is just an implementation detail, it could very well be the future numeric ID (if Django could know this before talking to the DB), in which case the query would become `.exclude(related_field=<an ID that's not in the DB yet>)`, which matches the intuitive reasoning behind that `exclude` call. For that reason, i would strongly suggest option (a) that you mentioned over the other two. -- Ticket URL: <https://code.djangoproject.com/ticket/25467#comment:10> 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.
