Detailed Description

The field under validation must contain one of the following acceptable input values: 1, 0, true, false, on or off.

Note: Unless validation is started with NoTrimming, whitespaces will be removed from the beginning and the end of the input value before validation. If the field's value is empty or if the field is missing in the input data, the validation will succeed without performing the validation itself. Use one of the required validators to require the field to be present and not empty.

Return type: On success, ValidatorReturnType::value will contain a bool value.

See also: Validator for general usage of validators.

Constructor & Destructor Documentation

◆ ValidatorBoolean()

ValidatorBoolean::ValidatorBoolean	(	const QString &	field,
		const ValidatorMessages &	messages = `ValidatorMessages()`,
		const QString &	defValKey = `QString()`
	)

Constructs a new ValidatorBoolean with the given parameters.

Parameters

field	Name of the input field to validate.
messages	Custom error message if validation fails.
defValKey	Stash key containing a default value if input field is empty. This value will NOT be validated.

Definition at line 15 of file validatorboolean.cpp.

◆ ~ValidatorBoolean()

ValidatorBoolean::~ValidatorBoolean ( )

overridedefault

Destroys the ValidatorBoolean object.

Member Function Documentation

◆ genericValidationError()

QString ValidatorBoolean::genericValidationError	(	Cutelyst::Context *	c,
		const QVariant &	errorData = `QVariant()`
	)		const

overrideprotectedvirtual

Returns a generic error message if validation failed.

Reimplemented from Cutelyst::ValidatorRule.

Definition at line 47 of file validatorboolean.cpp.

References QString::arg(), QString::isEmpty(), Cutelyst::ValidatorRule::label(), and Cutelyst::Context::qtTrId().

◆ validate()

ValidatorReturnType ValidatorBoolean::validate	(	Context *	c,
		const ParamsMultiMap &	params
	)		const

overrideprotectedvirtual

Performs the validation on the input params and returns the result.

If validation succeeded, ValidatorReturnType::value will either contain true if the input value contains 1, true or \on, or false if value contains 0, false or off.

Implements Cutelyst::ValidatorRule.
