Recently, I encountered a challenge when trying to serialize an object in XML for a client application on App Engine. Initially, I turned to Django 1.2 serialization as outlined in the documentation:
http://docs.djangoproject.com/en/1.2/topics/serialization/
from django.core import serializers
....
data = serializers.serialize("xml", TestObject.all())
However, this approach led to an error message:
raise base.SerializationError("Non-model object (%s) encountered during serialization" % type(obj))
SerializationError: Non-model object () encountered during serialization
This error appears to be caused by Django's lack of support for App Engine's db.Model objects. I am now seeking alternative methods to achieve my goal. Any suggestions would be greatly appreciated.
