Mapping

Abstract Value Members

abstract def bind(data: Map[String, String]): Either[Seq[FormError], T]

Binds this field, i.
Binds this field, i.e. construct a concrete value from submitted data.
data
the submitted data
returns
either a concrete value of type T or a set of errors, if the binding failed
abstract val constraints: Seq[Constraint[T]]

The constraints associated with this field.
abstract val key: String

The field key.
abstract val mappings: Seq[Mapping[_]]

Sub-mappings (these can be seen as sub-keys).
abstract def unbind(value: T): (Map[String, String], Seq[FormError])

Unbinds this field, i.
Unbinds this field, i.e. transforms a concrete value to plain data.
value
the value to unbind
returns
either the plain data or a set of errors, if the unbinding failed
abstract def verifying(constraints: Constraint[T]*): Mapping[T]

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) )
```
constraints
the constraints to add
returns
the new mapping
abstract def withPrefix(prefix: String): Mapping[T]

Constructs a new Mapping based on this one, adding a prefix to the key.
Constructs a new Mapping based on this one, adding a prefix to the key.
prefix
the prefix to add to the key
returns
the same mapping, with only the key changed
