def verifying(error: â String, constraint: (T) â Boolean): Mapping[T]
Constructs a new Mapping based on this one, by adding a new ad-hoc constraint.
Constructs a new Mapping based on this one, by adding a new ad-hoc constraint.
For example:
import play.api.data._
import validation.Constraints._
Form("phonenumber" -> text.verifying("Bad phone number", {_.grouped(2).size == 5}))
-
error
-
The error message used if the constraint fails
-
constraint
-
a function describing the constraint that returns false on failure
-
