Detailed Description

This validator checks if the input field can be parsed into a QDate, it will check the parsing ability and will convert the input data into a QDate. If a custom inputFormat is given, the validator will at first try to parse the date according to that format. If that fails or if there is no custom inputFormat set, it will try to parse the date based on standard formats in the following order: Context locale's toDate() with QLocale::ShortFormat and QLocale::LongFormat, Qt::ISODate, Qt::RFC2822Date, Qt::TextDate

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 QDate.

Constructor & Destructor Documentation

◆ ValidatorDate()

ValidatorDate::ValidatorDate	(	const QString &	field,
		const char *	inputFormat = `nullptr`,
		const ValidatorMessages &	messages = `ValidatorMessages()`,
		const QString &	defValKey = `QString()`
	)

Constructs a new ValidatorDate with the given parameters.

Parameters

field	Name of the input field to validate.
inputFormat	Optional input format for input data parsing, can be translatable.
messages	Custom error messages if validation fails.
defValKey	Stash key containing a default value if input field is empty. This value will NOT be validated.

Member Function Documentation

◆ genericValidationError()

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

overrideprotectedvirtual

Returns a generic error if validation failed.

Reimplemented from Cutelyst::ValidatorRule.

◆ validate()

ValidatorReturnType ValidatorDate::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 contain the input paramater value converted into a QDate.
