We can have compatibility checks that explicitly look for the contrib app strings in INSTALLED_APPS, and raise an error to the effect that "your app isn't being fully validated". Core compatibility checks aren't tied to apps embedded in the system, so they always run, so you wouldn't be able to do a syncdb/migrate or runserver without hitting an error that has hint telling you want you need to do. The migration itself is simple -- modify three lines in your INSTALLED_APPS, and you never see it again. It's just a question of whether we'd prefer a hands-off migration using an implicit technique, or a hands-on migration pointed to by the checks framework. > In Django 2.0 we do away with all the implicit importing and searching and > you have to configure your AppConfig instances for management commands, > template directories, static dirs, models, admin config... ;) > Oh, that mystical land of Django 2.0, where the sun shines shiner … :-) Russ %-) -- You received this message because you are subscribed to the Google Groups "Django developers" group.
