I had an existing Django project that I've just added South to.

I ran syncdb locally. I ran manage.py schemamigration app_name locally I ran manage.py migrate app_name --fake locally I commit and pushed to heroku master I ran syncdb on heroku I ran manage.py schemamigration app_name on heroku I ran manage.py migrate app_name on heroku

I then receive this:

$ heroku run python notecard/manage.py migrate notecards
Running python notecard/manage.py migrate notecards attached to terminal... up, run.1
Running migrations for notecards:
 - Migrating forwards to 0005_initial.
 > notecards:0003_initial

I have 3 models. Section, Semester, and Notecards. I've added one field to the Notecards model and I cannot get it added on Heroku.

Thank you.
