This validator checks that the ``data`` attribute on the field is a 'true' value (effectively, it does ``if field.data``.) Furthermore, if the data is a string type, a string containing only whitespace characters is considered false. If the data is empty, also removes prior errors (such as processing errors) from the field. **NOTE** this validator used to be called `Required` but the way it behaved (requiring coerced data, not input data) meant it functioned in a way which was not symmetric to the `Optional` validator and furthermore caused confusion with certain fields which coerced data to 'falsey' values like ``0``, ``Decimal(0)``, ``time(0)`` etc. Unless a very specific reason exists, we recommend using the :class:`InputRequired` instead. :param message: Error message to raise in case of a validation error.
