Project description

vjson

0.1.0

vjson creates an object to serialize the only of the type specified in JSONSchema. It works like a json module.

install

Next, execute command.:

$ pip install vjson

How to use

You define an object using JSONSchema.:

>>> import vjson
>>> _json = vjson.ValidatedJSON({
... 'type': 'object',
... 'properties': {
...     'price': {'type': 'number'},
...     'name': {'type': 'string'},
...     },
... })

This object can dumps/loads()/dump()/load() the serializable object, as in the json module.:

>>> _json.loads('{"name" : "Eggs", "price" : 34.99}')
{'name': 'Eggs', 'price': 34.99}
>>> _json.dumps({"name": "Eggs", "price": 34.99})
'{"name": "Eggs", "price": 34.99}'

If you try to pass the data that violates the JSONSchema that was specified in the constructor, it raises a vjson.JSONValidationError.:

>>> _json.loads('{"name" : "Eggs", "price" : "34.99"}')

During handling of the above exception, another exception occurred:
