The Cutelyst Context.
Definition: context.h:38
QString translate(const char *context, const char *sourceText, const char *disambiguation=nullptr, int n=-1) const
Definition: context.cpp:477
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.
bool trimBefore() const noexcept
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.
QString debugString(Context *c) const
Returns a string that can be used for debug output if validation fails.
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.
