Answer 1

While reading the book Play for Scala, I picked up this code snippet that was defined in a controller, which might be a better syntax for getOrElse.

def show(ean: Long) = Action { implicit request =>

  Product.findByEan(ean).map { product =>
    Ok(views.html.products.details(product))
  }.getOrElse(NotFound)

}

In which, the Product.findByEan(ean: Long) was defined like

def findByEan(ean: Long) = products.find(_ean == ean)
