        }
    }
}

NoneProp

It should be noted that missing referenced properties, including nested, are gracefully falsey.

>>> import RestResponse
>>> data = RestResponse.parse({})
>>> data.property.is_none
None
>>> bool(data.property.is_none)
False
>>> isinstance(data.property.is_none, RestResponse.NoneProp)
True
>>> data.property.is_none = None
>>> isinstance(data.property.is_none, RestResponse.NoneProp)
False
>>> print data.pretty_print()
{
    "property": {
        "is_none": null
    }
}

SQLAlchemy ORM

RestResponse uses a Mutable mixin provided by SQLAlchemy for interfacing with databases. The following (Flask) snippet should get you started:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from RestResponse.orm.sqlalchemy import RESTResponse


app = Flask(__name__)
db = SQLAlchemy(app)


class SomeModel(db.Model):
    id = db.Column(db.Integer(), primary_key=True)
    data = db.Column(RESTResponse(), nullable=False)

    def __init__(self, data):
        self.data = data # data should be json serializable

Data will be saved to the database as a serialized json blob. When data is loaded it will be coerced to the underlying RestResponseObj

Testing

$ pytest -s tests.py
