QString translate(const char *context, const char *sourceText, const char *disambiguation=nullptr, int n=-1) const
Definition: context.cpp:480
Checks if two values are different.
ValidatorDifferent(const QString &field, const QString &other, const char *otherLabel=nullptr, const ValidatorMessages &messages=ValidatorMessages())
Constructs a new different validator.
~ValidatorDifferent() override
Deconstructs the different validator.
ValidatorReturnType validate(Context *c, const ParamsMultiMap &params) const override
Performs the validation and returns the result.
QString genericValidationError(Context *c, const QVariant &errorData=QVariant()) const override
Returns a generic error if validation failed.
Base class for all validator rules.
QString label(Context *c) const
Returns the human readable field label used for generic error messages.
QString field() const
Returns the name of the field to validate.
bool trimBefore() const
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 validationError(Context *c, const QVariant &errorData=QVariant()) const
Returns a descriptive error message if validation failed.
The Cutelyst namespace holds all public Cutelyst API.
