Hey Nicola, Django's migration system doesn't natively support "drop this foreign key constraint from the database", because you shouldn't be able to run into such a situation with the migration system at all (if you do, that's a bug from my point of view). I suggest you go with a "RunSQL" operation where you drop the constraint: https://docs.djangoproject.com/en/1.7/ref/migration-operations/#django.db.migrations.operations.RunSQL
