South: stable and databas­e-independen­t migrations with Anna Callahan

The South migration package is about to become part of Django proper -- and it’s about time!  South is a must-have tool for keeping your database updated.

This talk will introduce South, cover the basics, and dive into a few more advanced uses.  In addition to a well-rounded intro, we’ll cover: schema migrations, data migrations, and rolling back; how South deals with model inheritance; and shortcuts to hairy data migrations like moving models from one app to another.

About the speaker

Anna Callahan is a Django and iOS developer.  She is the founder and CTO of ZoomTilt (Django); did iOS development at Raizlabs; was a Python and Rails programmer at 3M; and considers herself lucky to no longer be programming in C++ and PHP.

    Pres was great. But I'm really writing to the other person whose fleece sweater was snatched by the Meadhall waitstaff and brought to the front desk: You have my fleece (with the InsightSquared logo) and the front desk still has yours. You can do a prisoner exchange at Meadhall. thx

      The audio is good, but the slides aren't that readable in the video, are there slides available for the talk?

    We'll be video recording the talk tonight thanks to Chris Ball, and hopefully live streaming the event as well. I'll post the live stream URL here tonight shortly before the event starts.
