vjson 0.1

Description:

vjson 0.1

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"}')
