South - Not detecting changes to Django model

Question

I have Django model that I already have initialized with south using ./manage.py schemamigration (appname) --initial. All was going well through this point, until I decided I needed another field. I added another field and tried to to migrate the change with ./manage.py schemamigration (appname) --auto, but it says:

- Nothing to migrate.

I made sure to migrate the initial changes. Seems to be similar to the problem here, but the solution got me nowhere.

Answer 1

It's probably because between the --initial migration and the next schemamigration you have to persist the actual migration to the db issuing the command python manage.py migrate my_app.

After doing that first migration then you may add another field, do and schemamigration --auto and commit it to the db again by doing python manage.py migrate my_app

Hope this helps!
