Value parameters
- binder
-
the new binder to use
Attributes
- Returns
-
the same mapping with a new binder
Binds this field, i.e. constructs a concrete value from submitted data.
Binds this field, i.e. constructs a concrete value from submitted data.
Value parameters
- data
-
the submitted data
Attributes
- Returns
-
either a concrete value of type
Tor a set of errors, if binding failed
Unbinds this field, i.e. transforms a concrete value to plain data.

-
the plain data
Unbinds this field, i.e. transforms a concrete value to plain data, and applies validation.

For example:
import play.api.data._
import validation.Constraints._
Form("phonenumber" -> text.verifying(required) )
Value parameters

-
the constraints to add
Attributes
- Returns
-
the new mapping

Value parameters
- prefix
-
the prefix to add to the key
Attributes
- Returns

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._

Form("phonenumber" -> text.verifying("Bad phone number", {_.grouped(2).size == 5}))
Value parameters
- constraint
-
a function describing the constraint that returns
falseon failure - error
-
The error message used if the constraint fails
Attributes
- Returns
-
the new mapping
