Trouble using South with Django and Heroku
- by Dan
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.
