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.
qsizetype size() const const
QString fromUtf8(QByteArrayView str)
~ValidatorSame() override
Deconstructs the same validator.
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
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.
ValidatorReturnType validate(Context *c, const ParamsMultiMap &params) const override
Performs the validation and returns the result.
ValidatorSame(const QString &field, const QString &otherField, const char *otherLabel=nullptr, const ValidatorMessages &messages=ValidatorMessages(), const QString &defValKey=QString())
Constructs a new same validator.
QString value(const ParamsMultiMap &params) const
Returns the value of the field from the input params.
QString field() const
Returns the name of the field to validate.
Contains the result of a single input parameter validation.
Definition: validatorrule.h:49
QString arg(Args &&... args) const const
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 ...
T value(const Key &key, const T &defaultValue) const const
void setValue(QVariant &&value)
The given field must match the field under validation.
