A general purpose Python data validator.
Schema format based on JSON Schema Proposal (http://json-schema.org)
Contains code derived from jsonschema, by Ian Lewis and Yusuke Muraoka.
JSON documents and schema must first be loaded into a Python dictionary type before it can be validated.
Parsing a simple JSON document:
>>> import validictory
>>>
>>> validictory.validate("simplejson", {"type":"string"})Parsing a more complex JSON document:
>>> import simplejson
>>> import validictory
>>>
>>> data = simplejson.loads('["foo", {"bar":["baz", null, 1.0, 2]}]')
>>> schema = {
... "type":"array",
... "items":[
... {"type":"string"},
... {"type":"object",
... "properties":{
... "bar":{
... "items":[
... {"type":"string"},
... {"type":"any"},
... {"type":"number"},
... {"type":"integer"}
... ]
... }
... }
... }
... ]
... }
>>> validictory.validate(data,schema)Catch ValueErrors to handle validation issues:
>>> import validictory
>>>
>>> try:
... validictory.validate("simplejson", {"type":"string","minLength":15})
... except ValueError, error:
... print error
...
Length of value 'simplejson' for field '_data' must be greater than or equal to 15
