Valedictory - validate Python dictionaries

Declare a schema, then validate Python dictionaries against it:

from valedictory import Validator, fields, InvalidDataException

class ContactValidator(Validator):
    name = fields.CharField()
    height = fields.IntegerField()
    date_of_birth = fields.DateField()

contact_validator = ContactValidator()

input_data = json.loads(request.body)

    cleaned_data = contact_validator.clean(input_data)

    # Save the data

except InvalidDataException as errors:
    # Handle the error
    for path, message in errors.flatten():
        print("{0}: {1}".format('.'.join(path), message))
