What is validictory? A simple Python library to validate JSON data.

What do you use it for? Validate web service APIs that talk JSON.

How does it work? One function. Two arguments.
>>> import validictory >>> validictory.validate(data, schema)

How does it work? What is ``data`` ? A Python datatype loaded from JSON data.
>>> import json >>> data = json.loads(request.body)

How does it work? What is ``schema`` ? A Python dictionary describing how the data should be formed.
>>> schema = {”type”: ”string”, ... ”minLength”: 2, ... ”maxLength”: 2}

How does it work? Invalid data.
>>> validictory.validate(”USA”, schema) Traceback (most recent call last): ValidationError: Length of value 'USA' for field '_data' must be less than or equal to 2

How does it work? Re-usable schemas, just plain Python.
>>> country = {”type”: ”string”, ... ”minLength”: 2, ... ”maxLength”: 2} >>> address = {”type”: ”object”, ... ”properties”: { ... ”street”: {”type”:”string”}, ... ”country”: country }}
