The Cutelyst Context.
Definition: context.h:39
QString translate(const char *context, const char *sourceText, const char *disambiguation=nullptr, int n=-1) const
Definition: context.cpp:477
QString genericValidationError(Context *c, const QVariant &errorData=QVariant()) const override
Returns a generic error message if validation failed.
~ValidatorBoolean() override
Deconstructs the validator.
ValidatorBoolean(const QString &field, const ValidatorMessages &messages=ValidatorMessages(), const QString &defValKey=QString())
Constructs a new validator.
ValidatorReturnType validate(Context *c, const ParamsMultiMap &params) const override
Performs the validation and returns the result.
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.
void defaultValue(Context *c, ValidatorReturnType *result, const char *validatorName) const
I a defValKey has been set in the constructor, this will try to get the default value from the stash ...
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.
Definition: Mainpage.dox:8
QMultiMap< QString, QString > ParamsMultiMap
Stores custom error messages and the input field label.
Contains the result of a single input parameter validation.
