* component: Database layer (models, ORM) => Documentation * type: Bug => Cleanup/optimization * stage: Unreviewed => Accepted Comment: I don't think it's a good idea to change the behavior, so I'll accept as a documentation patch. Especially for custom `Prefetch`'s it's probably impossible to implement correct behavior "in-memory" (e.g. if `Prefetch` has a custom queryset, we'd have to determine if the new object matches it). Feel free to raise the issue on the DevelopersMailingList if you feel I'm wrong. -- Ticket URL: <https://code.djangoproject.com/ticket/25344#comment:3> 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.
