Add field to existing django app in production environment
first is to fake the initial migration:
python manage.py migrate [yourapp] --fake 0001
then you can apply the migration to the db
python manage.py migrate [yourapp]

I'm assuming you ran convert_to_south on development, in which case production still wouldn't be aware of the migrations yet.  convert_to_south automatically fakes the initial migration for you!  If you were to just run migrate on production without faking, it should error.
I have an existing django app and would like to add a field to a model.
But because the website is already in production, just deleting the database is not an option any more.
These are the steps I took:

pip install south
added 'south' to INSTALLED_APPS
python manage.py syncdb
python manage.py convert_to_south [myapp]

So now I have the initial migration and south will recognize the changes. Then I added the field to my model and ran:

python manage.py schemamigration [myapp] --auto
python manage.py migrate [myapp]

Now I have the following migrations:

0001_initial.py
0002_auto__add_field_myapp_fieldname.py

Which commands should I run on my production server now to migrate? Also should I install south first and then pull the code changes and migrations?
