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.
ValidatorReturnType validate(Context *c, const ParamsMultiMap &params) const override
Performs the validation and returns the result.
Checks if two values are different.
The Cutelyst Context.
Definition: context.h:38
bool isEmpty() const const
bool trimBefore() const
Returns true if the field value should be trimmed before validation.
QString translate(const char *context, const char *sourceText, const char *disambiguation=nullptr, int n=-1) const
Definition: context.cpp:490
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.
void setValue(const T &value)
QString value(const ParamsMultiMap &params) const
Returns the value of the field from the input params.
QString genericValidationError(Context *c, const QVariant &errorData=QVariant()) const override
Returns a generic error if validation failed.
QString arg(qlonglong a, int fieldWidth, int base, QChar fillChar) const const
