Running Django Apps on Google App Engine


Running Django Apps on Google App Engine

Presented by wesley chun

In the past, Django users couldn't run apps unmodified on Google App Engine. Some tools helped with integration but required you to change your data models. Django-nonrel removes this requirement letting you run native Django apps on App Engine with only config changes if you bear in mind its restrictions like no JOINs. In this talk, we'll discuss Django-nonrel & porting App Engine apps to Django.


Previously, Django users could not get their apps to run unmodified on Google App Engine, the cloud application-hosting platform. Older tools like "the Helper" and "the Patch" required a change to the data models as well as perhaps integrating additional tools into the application source tree. The creators of the Patch realized how cumbersome this is and created a replacement for all of these older tools.

Django-nonrel allows users to run pure Django apps on App Engine with only minor configuration changes. It basically enables Django's ORM to operate on top of non-relational databases (in addition to preserving its ability to support standard relational DBs), one of which is Google App Engine's Datastore. (MongoDB is another.)

What this means that current Django users can now use their existing knowledge to write apps for App Engine as long as they keep App Engine restrictions in mind, e.g., no JOINs. Projects written in this manner will work without any modifications other than changing the configuration settings. On the other side, App Engine developers now have an alternative to the '"webapp" framework that comes with its SDK. You can now leverage the power of a full web framework like Django and still enjoy the flexibility and scalability of App Engine. In this talk, we'll discuss Django-nonrel, and how to port App Engine apps from webapp to pure Django to run on App Engine using Django-nonrel.
