Adding Custom Values

You might encounter cases where you wish to include additional data in a response which is not obtained from a field or method on your model. You can easily extend the dehydrate() method to provide additional values:

class MyModelResource(Resource):
    class Meta:
        qs = MyModel.objects.all()

    def dehydrate(self, bundle):
        bundle.data['custom_field'] = "Whatever you want"
        return bundle
