I've created a model and created initial migration for it:
db.create_table('tvguide_tvguide', (
('id', models.AutoField(primary_key=True)),
('date', models.DateField(_('Date'), auto_now=True, db_index=True)),
))
db.send_create_signal('tvguide', ['TVGuide'])
models = {
'tvguide.tvguide': {
'channels': ('models.ManyToManyField', ["orm['tvguide.Channel']"], {'through': "'ChannelInTVGuide'"}),
'date': ('models.DateField', ["_('Date')"], {'auto_now': 'True', 'db_index': 'True'}),
'id': ('models.AutoField', [], {'primary_key': 'True'})
}
}
complete_apps = ['tvguide']
Now, I'd like to drop it:
db.drop_table('tvguide_tvguide')
However, I have also deleted corresponding model. South (at least 0.6.2) is however trying to access it:
(venv)[almad@eva-03 project]$ ./manage.py migrate tvguide
Running migrations for tvguide:
- Migrating forwards to 0002_removemodels.
> tvguide: 0001_initial

Is there a way around?
