QString validationError(Context *c, const QVariant &errorData=QVariant()) const
Returns a descriptive error message if validation failed.
Stores custom error messages and the input field label.
QString genericValidationError(Context *c, const QVariant &errorData=QVariant()) const override
Returns a generic error message if validation failed.
The Cutelyst Context.
Definition: context.h:38
~ValidatorBoolean() override
Deconstructs the validator.
CaseInsensitive
bool isEmpty() const const
ValidatorReturnType validate(Context *c, const ParamsMultiMap &params) const override

The Cutelyst namespace holds all public Cutelyst API.
Definition: Mainpage.dox:7
Base class for all validator rules.
QString label(Context *c) const
Returns the human readable field label used for generic error messages.
QString value(const ParamsMultiMap &params) const
Returns the value of the field from the input params.
ValidatorBoolean(const QString &field, const ValidatorMessages &messages=ValidatorMessages(), const QString &defValKey=QString())
