Constructs a new Mapping based on this one, by adding new constraints.
Constructs a new Mapping based on this one, by adding new constraints.
For example:
import play.api.data._ import validation.Constraints._ Form("phonenumber" -> text.verifying(required) )

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}))
The error message used if the constraint fails
a function describing the constraint that returns false
on failure
