ValidatorRequiredUnless(const QString &field, const QString &otherField, const QStringList &otherValues, const ValidatorMessages &messages=ValidatorMessages())
Constructs a new required unless validator.
QString genericValidationError(Context *c, const QVariant &errorData=QVariant()) const override
Returns a generic error message if validation failed.
ValidatorReturnType validate(Context *c, const ParamsMultiMap &params) const override
Performs the validation and returns the result.
~ValidatorRequiredUnless() override
Deconstructs the required unless validator.
Base class for all validator rules.
QString label(Context *c) const
Returns the human readable field label used for generic error messages.
bool trimBefore() const noexcept
Returns true if the field value should be trimmed before validation.
QString value(const ParamsMultiMap &params) const
Returns the value of the field from the input params.
QString validationDataError(Context *c, const QVariant &errorData=QVariant()) const
Returns an error message if any validation data is missing or invalid.
QString validationError(Context *c, const QVariant &errorData=QVariant()) const
Returns a descriptive error message if validation failed.
QString debugString(Context *c) const
Returns a string that can be used for debug output if validation fails.
The Cutelyst namespace holds all public Cutelyst API.
