docs: def as_obj(func):
      """ A decorator used to return a JSON response with a dict
          representation of the model instance.  It expects the decorated function
          to return a Model instance. It then converts the instance to dicts
          and serializes it into a json response
  
          Examples:
  
              >>> @app.route('/api/shipments/<id>')
              ... @as_obj
              ... def get_shipment(id):
