SimpleJSON can't serialize arbitrary Python objects (this includes Django model instances). Django provides a serialization library (django.core.serializers) which can serialize model instances, but this doesn't output in the specific format you require. You have three options: 1) Write a function that converts the model objects you have into a python dictionary matching the format you require, then pass the dictionary through SimpleJson. 2) Use the Django serializer as-is, and convert the JSON structure into the required format on the client side. 3) Write a custom extension of django.core.serializer.json.Serializer. As a guideline, you will be need to overwrite the end_object method to construct Python in the format you require. Although (3) sounds daunting, it shouldn't be that difficult. The original implementation (in serializer.base.Serializer) is only 7 lines of code, and pretty self explanatory. In fact, it's very similar to option (1) - except that the heavy lifting of model traversal has been done for you.
