Difference between Flash Scope and Request Scope

What is the difference between Flash Scope and View Scope?

Can someone please explain it with an example?

Regards,

Solution

  • Flash Scope From the DOC:

    The Flash scope works exactly like the Session, but with two differences: data are kept for only one request the Flash cookie is not signed, making it possible for the user to modify it.

    Example:

    public static Result index() {
  String message = flash("success");
  if(message == null) {
    message = "Welcome!";
  }
  return ok(message);
}

public static Result save() {
  flash("success", "The item has been created");
  return redirect("/home");
}

    Request Scope is straight forward, it exists for a particular request only.
