kodekracker / json_encoder.py
Last active November 20, 2018 12:36
A Custom SqlAlchemy JSON encoder class to encode models instances in json format which supports major object instances useful in developing api's in flask.
# To use this custom JsonEncoder class, you have to create a __json__() named
# function in each sqlalchemy model class, which basically return a list of model
# class attributes to be parsed, otherwise all attributes are processed present
# in `dir(class_name)`.
#
# Model Example:
# class User(db.Model):
# id = db.Column(db.Integer, primary_key=True)
# name = db.Column(db.String(100))
# email = db.Column(db.String(100))
