------------------------------------------+--------------------------------
In multiple different projects now, I've needed to connect Django to
legacy databases that aren't under Django's control. Even when setting
"manage = False" in all affected models and configuring the DB router to
never allow migrate in the legacy database, Django "makemigrations" still
attempts to create the django_migrations table, causing permission errors
in my use case.
The pull request changes MigrationRecorder is so that for read-only
operations, if the django_migrations table doesn't exist, it's assumed
that no migrations have been applied, instead of trying to create it. This
applies to all migration commands.
Django has always had the problem of being "opinionated", meaning there's
often fighting involved if you don't exactly follow The True Django way.
:) This patch is a small step in making Django more flexible.
PS: I understand that version 1.11 is alreday in a feature freeze, but is
there aaaaany chance of getting this patch in there?
