I have removed an app that contained a couple of custom fields from my project. Now when I try to run my migrations I get ImportError, naturally. These fields were very basic customizations like below:
from django.db.models.fields import IntegerField
class SomeField(IntegerField):
def get_internal_type(self):
return "SomeField"
def db_type(self, connectio=None):
return 'integer'
def clean(self, value):
# some custom cleanup
pass
So, none of them contain any database level customizations.
When I removed this code, I've created migrations so the subsequent migration all ran fine. But when I try to run them on a pre-deletion database I realized my mistake.
I can re-create a bare-bones app and make these imports work, but Ideally I would like to know if South has a mechanism to resolve these issues? Or is there any best practises? It would be cool if I could solve these issues just by modifying my migrations and not touching the codebase.
(Django 1.3, South 0.7.3)
