Damn Simple Validation Kit.

Project description

About

Validate dict-like object against schema, using just callables.

Features

  • Allows validating and sanitizing dicts using any callables
  • Provides several useful helpers
  • Easy to use – no class-based boilerplate!

API

validate function takes any mapping as data and another mapping as scheme and check data against scheme. It returns list of errors.

sanitize function takes any mapping as data and another mapping as scheme and converts data according to schema definition.

For more info – see tests.

Examples

Several schemes:

schema = {
    'key1': str,
    'key2': int,
    'key3': int,
}

schema1 = {
    'key1': kuvalda.list_of(int),
    'key2': kuvalda.list_of(kuvalda.list_of(int))
}

schema2 = {
   'section1': {
       'key1': str,
       'key2': int
    },
    'section2': kuvalda.mapping(str, int),
    'key1': kuvalda.kind_of(bool)
}

schema3 = {
    'key1': int,
    'key2': kuvalda.default('oh, my'),
    'key3': kuvalda.optional(int),
    'key4': kuvalda.optional(kuvalda.list_of(int)),
    'key5': kuvalda.compose(kuvalda.default(42), int)
}
