Migration for model inherited from Django
Based on my investigation and on comments provided, it looks like there is no solution for the moment.
We're using CustomFlatPage model derived from django.FlatPage model in our application. It works fine, but the FlatPage changed in Django 1.9, which triggers the migration for our CustomFlatPage. But we'd like to have a clean migrations, that is state where makemigrations doesn't create any migrations in 1.8, nor 1.9.
Is it possible to write a migration which would be compatible with Django 1.8 and 1.9 without any change to the CustomFlatPage model itself?
