Warlock

Build self-validating python objects using JSON schemas.

Create your schema

schema = { 'name': 'Country', 'properties': { 'name': {'type': 'string'}, 'abbreviation': {'type': 'string'}, 'population': {'type': 'integer'}, }, 'additionalProperties': False, }
Create a model

import warlock Country = warlock.model_factory(schema)
Create an object using your model

sweden = Country(name='Sweden', abbreviation='SE')
Let the object validate itself

sweden.name = 5 Traceback (most recent call last): File "", line 1, in File "warlock/core.py", line 53, in setattr raise InvalidOperation(msg) warlock.core.InvalidOperation: Unable to set 'name' to '5'

sweden.overlord = 'Bears' Traceback (most recent call last): File "", line 1, in File "warlock/core.py", line 53, in setattr raise InvalidOperation(msg) warlock.core.InvalidOperation: Unable to set 'overlord' to 'Bears'
Generate a JSON Patch document to track changes

sweden.population=9453000 sweden.patch '[{"path": "/population", "value": 9453000, "op": "add"}]'
