Abstract Value Members
- abstract def bind(key: String, data: Map[String, String]): Either[Seq[FormError], T]
Binds this field, i.e.
Binds this field, i.e. constructs a concrete value from submitted data.
- key
the field key
- data
the submitted data
- returns
Either a concrete value of type T or a set of error if the binding failed.
- abstract def unbind(key: String, value: T): Map[String, String]
Unbinds this field, i.e.
Unbinds this field, i.e. transforms a concrete value to plain data.
- key
the field ke
- value
the value to unbind
- returns
either the plain data or a set of errors if unbinding failed
