I\'ve been searching for quite a while with no success. My project isn\'t using Django, is there a simple way to serialize App Engine models (google.appengine.ext.db.Model)
If you use app-engine-patch it will automatically declare the _meta attribute for you, and then you can use django.core.serializers as you would normally do on django models (as in sledge's code).
App-engine-patch has some other cool features such has an hybrid authentication (django + google accounts), and the admin part of django works.
