profile.iiita.ac.inREST services implemented with Django REST Framework 1. Map services to models. Model fields store the states (on/off, auto/manual) 2. Write Model serializers. Serializers allow complex data (such as model instances) to be converted to native Python datatypes that can then be easily rendered into JSON, XML or other content types.
