will be helpful for those in need Wow, South sounds pretty awesome! I'm not sure of anything out-of-the-box that will help you nearly as much as that does, however if you choose Hibernate as your ORM solution you can build your own incremental data migration suite without a lot of trouble.
Here was the approach that I used in my own project, it worked fairly well for me for over a couple of years and several updates/schema changes:

I hope this helps . What's actually going on in your migrations? If you're getting this error then simply create_table is being called twice for blog_blog or blog_blog already existed in your database before the initial migration (perhaps, a leftover from a previous attempt at creating a blog that never got migrated to zero).
If the error is occurring before the initial migration completes, then it's most likely an artifact, and you can just remove it from your database manually and try again. If the initial migration succeeds but a later migration fails, then find where there's a duplicate create_table for blog_blog.

I wish did fix the issue. We've discovered this Django ticket that pretty much states that this is a design pattern that the devs aren't supporting, so we're just going to have to rewrite the model to explicitly create the other fields on the model and then reference said fields from the "parent" field a la ImageField.
