Sync django with south
Suppose, that your old project's models definition are consistent with database.
And you want to edit some model(s) in app named 'myappName'.
Then your algorithm will be following:

Before making any changes to you model, do:
python manage.py convert_to_south myappName
Modify model(s) in app 'myappName'.
Create migrations:
python manage.py schemamigration myappName --auto
Apply migrations:
python manage.py migrate myappName
Have installed south to my old django project.
Have run.
¤ syncdb
¤ convert_to_south myappName
But the did not sync all.
Runned:
¤ Migrate myappNAme
Did not sync 100 %, still have one column that is not found.
Runned:
¤ schemamigration -auto myappName
But not synced to 100 %....
Any ideas?
