Redirect in Scala play framework

I have a problem with Redirect in Scala play framework.

How can I redirect to view BooksController.index() ? In documentation they suggest to use Redirect but I don't know how.

def edit(Id: Int) = Action
val book: Book = Book.findById(Id)
Ok(views.html.edit())


def update = Action
implicit request =>
val (id, title, price, author) = bookForm.bindFromRequest.get
val book: Book = Book.findById(id)
book.id = id
book.title = title
book.price = price
book.author = author
Redirect(routes.BooksController.index())



Now can recognize --> import play.api.mvc.Results._
But i have an error --> "object java.lang.ProcessBuilder.Redirect is not a value"

If you would really like to continue using reverse routing in your code instead of having string uri values all over the place, see this:
Redirect with Bad Request Status.
The Redirect function accepts only a String or Call.

Try the following steps:

0) Add in the BookController

import play.api.mvc._


1) Add the following string in your route config file(hard disk location: controllers/BooksController)

GET /redirectedPage controllers.BooksController.index


2) Define a variable in the BookController

val Home = Redirect(routes.BookController.index())


3) Describe in the BookController

def update = Action
implicit request => Home



Also do "sbt clean; sbt compile" to recompile auto-calls in ReverseRoutes.scala.

Well done.

The last line in the update action is the Redirect call which redirects to BooksController index route

update

Redirect

index

import play.api.mvc.Results._

Redirect(routes.BooksController.index())


import play.api.mvc.Results._
