South migration schemamigration doesn't work

Just to make sure I have the setup right in my current django project, I did the following:

  • added south to installed_apps
  • manage.py syncdb (using windows)
  • manage.py convert_to_south app

I didn't make changes to my database yet but whether or not I do, I run:

  • manage.py schemamigration app --auto

and I get the following errors:

What's going on? It's not letting me use schemamigration. Been searching a lot of places and deleting and resetting the database and everything, can't seem to find out what the problem is.

Problem resolved:

Didn't know about south_migrationhistory location. I was always wondering about where some extra information was hanging.

Solution

  • Have a look here: http://south.aeracode.org/ticket/1069

    Its a bug that is fixed in newer South versions. It seems you are using an obsolete version of South(<=0.7.3)
