Extra fields

Active field

Converts active field to state and back.

>>> class SimpleSchema(Schema):
        active = Active()

>>> SimpleSchema().dump({'state': 'active'})
{'active': True})
>>> SimpleSchema().dump({'state': 'inactive'})
{'active': False}

>>> SimpleSchema().load({'active': True})
{'state': 'active'}
>>> SimpleSchema().load({'active': False})
{'state': 'inactive'}

Filter by query parameter:

>>> class SimpleFilterSchema(Schema):
        active = Active(as_filter=True)

>>> SimpleFilterSchema().load({'active': 'true'})
{'state': 'active'}
>>> SimpleFilterSchema().load({'active': 'false'})
{'state': 'inactive'}
>>> SimpleFilterSchema().load({})
{'state__ne': 'deleted'}

For experienced usage try positives, negatives, positive_filter, negative_filter, missing_filter parameters. You can see behaviour for this parameters in tests.
