                Ignoring migrations during Django testing (unmanaged databases, legacy databases, etc)
              
          
    Scenario


Django 1.9 application with two databases:

Legacy database with readonly access via unmanaged models.  Both Django models (models.py) and related migrations have "managed" set to False

'managed': False


Default database holding django specific tables (e.g. auth_user, django_content_type, etc)


Testing Woes


For testing I want to re-create the legacy database tables.  In other words, during python manage.py test, tell Django to set "managed" to True

There are several excellent blog posts on how to set "managed" to True during tests:
