Abstract Value Members

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

    Binds this field, i.e.

    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

  2. abstract val constraints: Seq[Constraint[T]]

    The constraints associated with this field.

  3. abstract val key: String

    The field key.

  4. abstract val mappings: Seq[Mapping[_]]

    Sub-mappings (these can be seen as sub-keys).

  5. abstract def unbind(value: T): Map[String, String]

    Unbinds this field, i.e.

    Unbinds this field, i.e. transforms a concrete value to plain data.

    value

    the value to unbind

    returns

    the plain data

  6. abstract def unbindAndValidate(value: T): (Map[String, String], Seq[FormError])

    Unbinds this field, i.e.

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

    value

    the value to unbind

    returns

    the plain data and any errors in the plain data

  7. 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

  8. 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

    B

    The type of the new mapping.

    f1

    Transform value of T to a value of B
