Question

I was using python 2.5 and django 1.0.2. But I moved to python 2.6 and django 1.2 recently and I’m getting the following error now during the migrate:

alex@alex-desktop:~/server/mx30$ python manage.py migrate
Running migrations for peer_center:
 - Migrating forwards to 0005_adding_config_model.
 > peer_center: 0001_initial

    db = kwargs['db']
KeyError: 'db'

After running migrate several times, it eventually passes.
I have 5 different apps under migration and I thought it can be dependencies issue. But I have no migrations calling other apps.
So what can be the problem?

Django 1.2 supports multiple DB’s, and the version of South you are running does not. Try checking out a more recent version – supposedly this was fixed at some point in 0.6, and should work in 0.7.
