I have a django app with four models in it. I realize now that one of these models should be in a separate app. I do have south installed for migrations, but I don't think this is something it can handle automatically. How can I migrate one of the models out of the old app into a new one? Also, keep in mind that I'm going to need this t...

Hello, I have an application which is in BETA mode. The model of this app has some classes with an explicit primary_key. As a consequence Django use the fields and doesn't create an id automatically. class Something(models.Model): name = models.CharField(max_length=64, primary_key=True) I think that it was a bad idea (see http://...
