Hello,
Thank you for using Googler Groups!
I believe it would be worthwhile for you to check the "running Django on Google App Engine" documentation. Specifically the section of the doc that discusses how to step up the database portion of your app. For the standard environment, you may refer to the "Initializing your Cloud SQL instance" section
here while the same guide for the flexible environment can be found
here. Let me know if you still encounter any issues once you followed the steps on how to configure your Cloud SQL instance with Django.
Hope this helps
