How to serialize SQLAlchemy query result to JSON format?

I tried

Answer 1

install simplejson by pip install simplejson and the create a class

class Serialise(object):

    def _asdict(self):
        """
        Serialization logic for converting entities using flask's jsonify

        :return: An ordered dictionary
        :rtype: :class:`collections.OrderedDict`
        """

        result = OrderedDict()
        # Get the columns
        for key in self.__mapper__.c.keys():
            if isinstance(getattr(self, key), datetime):
                result["x"] = getattr(self, key).timestamp() * 1000
                result["timestamp"] = result["x"]
            else:
                result[key] = getattr(self, key)

        return result

and inherit this class to every orm classes so that this _asdict function gets registered to every ORM class and boom. And use jsonify anywhere
