Mastering play framework for scala

Chapter 2. Defining Actions

If you're reading this, you've either survived the first chapter or skipped it. Either way, I am assuming you know the structure of a simple Play application. A controller in Play generates Action values and, to do so, it uses several objects and methods internally. In this chapter, we will see what goes on behind the scenes and how we can leverage these actions when we build our application.

In this chapter, we will be covering the following topics:

  • Defining Actions
  • Request body parsers
  • Action composition and troubleshooting

A dummy Artist model

In the following sections, we will give make reference to an artist model. It is a simple class with a companion object, defined as follows:

case class Artist(name: String, country: String)

object Artist {
  val availableArtist = Seq(Artist("Wolfgang Amadeus Mozart", "Austria"), 
    Artist("Ludwig van Beethoven", "Germany"), 
    Artist("Johann Sebastian Bach", "Germany"), 
    Artist("Frédéric François Chopin", "Poland"), 
    Artist("Joseph Haydn", "Austria"), 
    Artist("Antonio Lucio Vivaldi", "Italy"), 
    Artist("Franz Peter Schubert", "Austria"), 
    Artist("Franz Liszt", "Austria"), 
    Artist("Giuseppe Fortunino Francesco Verdi", "Austria")) 

  def fetch: Seq[Artist] = {
    availableArtist 
  } 

  def fetchByName(name: String): Seq[Artist] = {
    availableArtist...

Actions

An Action in Play defines how a server should respond to a request. The methods, which define an Action, are mapped to a request in the routes file. For example, let's define an Action which displays the information of all the artists as a response:

def listArtist = Action {
  Ok(views.html.home(Artist.fetch))
}

Now, to use this Action, we should map it to a request in the routes file.

GET     /api/artist       controllers.Application.listArtist

In this example, we fetch all the artists and send them with the view, as the response to the request.

Note

The term api used in the route file is just a URL prefix and is not mandatory.

Run the application and access http://localhost:9000/api/artist from the browser. A table with the available artist is visible.

Action takes a request and yields a result. It is an implementation of the EssentialAction trait. It is defined as:

trait EssentialAction extends (RequestHeader => Iteratee[Array[Byte], Result]) with Handler {
 
  def apply() = this...

Request body parsers

Consider the most common POST request in any application—the request sent for logins. Will it be sufficient if the request body has the user's credentials in, say, a JSON or XML format? Will the request handler be able to extract this data and process it directly? No, since the data in the request has to be understood by the application code, it must be translated into a compatible type. For example, XML sent in a request must be translated to Scala XML for a Scala application.

There are several libraries, such as Jackson, XStream, and so on, which can be used to achieve this task, but we wouldn't need them as Play supports this internally. Play provides request body parsers to transform the request body into equivalent Scala objects for some of the frequently used content types. In addition to this, we can extend existing parsers or define new ones.

Every Action has a parser. How do I know this ? Well, the Action object, which we used to define how our...

Extending a parser

Let's extend the JSON parser so that we get a subscription model. We will assume that the Subscription model is defined as follows:

case class Subscription(emailId: String, interval: String)

Now, let's write a parser that transforms the request body into a subscription object. The following code should be written in a controller:

val parseAsSubscription = parse.using {
    request => 
      parse.json.map {
        body => 
          val emailId:String = (body \ "emailId").as[String] 
          val fromDate:Long = (body \ "fromDate").as[Long] 
          Subscription(emailId, fromDate)
      }
  }

  implicit val subWrites = Json.writes[Subscription]
  def getSub = Action(parseAsSubscription) {
    request => 
      val subscription: Subscription = request.body
      Ok(Json.toJson(subscription))
   }

There are also tolerant parsers. By tolerant, we mean that errors in a format are not ignored. This simply means that it ignores the...

Exploring the results

In Play, the response to a request is a result. A result has two components: the response header and the response body. Let's look at a simple example of this:

def plainResult = Action {
  Result( 
    header = ResponseHeader(200, Map(CONTENT_TYPE -> "text/plain")), 
    body = Enumerator("This is the response from plainResult method".getBytes())
  )
}

Notice that we used an enumerator for the response body. An enumerator is a means to provide data to an iteratee. We will discuss these in detail in Chapter 6, Reactive Data Streams.

Apart from this, a result has additional functions that equips us with better means to handle response headers, sessions, cookies, and so on.

A result can send JSON, XML, and images as a response, apart from a String content. An easier way of generating a result is to use the result helpers. A result helper is used for most of the HTTP response status. As an example, let's see how the TODO Action that comes built...

    Artist("Franz Peter Schubert", "Austria"), 
    Artist("Franz Liszt", "Austria"), 
    Artist("Giuseppe Fortunino Francesco Verdi", "Austria")) 

  def fetch: Seq[Artist] = {
    availableArtist 
  } 

  def fetchByName(name: String): Seq[Artist] = {
    availableArtist.filter(a => a.name.contains(name)) 
  } 

  def fetchByCountry(country: String): Seq[Artist] = {
    availableArtist.filter(a => a.country == country) 
  }

Asynchronous Actions

Suppose that we are at a food court and place an order to eat something at a kiosk, we are given a token and a bill. Later, when the order is ready, the kiosk flashes the token number, and upon noticing it, we collect the order.

This is similar to a request with an asynchronous response cycle, where the kiosk acts like the server, the order acts similar to a request, and the token as a promise, which gets resolved when the order is ready.

Most operations are better handled asynchronously. This is also mostly preferred since it does not block server resources until the operation is completed.

Play Action is a helper object, which extends the ActionBuilder trait. The apply method of the ActionBuilder trait implements the Action trait, which we saw earlier. Let's take a look at the relevant code from the ActionBuilder trait:

trait ActionBuilder[+R[_]] extends ActionFunction[Request, R] { 
  self => 

  final def apply[A](bodyParser: BodyParser[A])(block: R[A] =>

If you are a beginner or intermediate level Scala developer interested in dabbling in web development, this is the book for you. Concepts are presented in a very easy to understand manner that will appeal to readers of all skill levels. The author discusses how to leverage the power of the Play framework to get the benefits of REST and MVC pattern without worrying about the nitty gritty details since the framework is designed to make everything manageable. Whether the readers are interested in connectivity with relational databases or NoSQL databases, this book has them covered. Additionally, entire chapters dedicated to websockets, testing, logging, debugging, web services and authentication serve to empower the users with all the knowledge they need to design and develop rock solid web applications. Finally, readers will see how to deploy their Play applications in production using popular web servers and writing their own custom Play plugins to take care of any functionality not offered by the framework.

Many books either assume the reader is already an expert of difficult sums and bombard one with complexity from page 1 or miss out important development steps such as Unit Testing and Debugging.Shiti Saxena follows a different and refreshing approach leading the student in the basics of Play right through to Development, Deployment and the Packaging of applications.

I am new to Scala and Play, so I did need a book to give me overall picture as well as detailed examples. Luckily, I bought the book and found it very useful for me. The book also explains quite well what is the implementation of Play in each subject, which I like too.Really good book and highly recommended (especially for beginners)!

The book is well structured and will be useful for understanding the basic principles of developing with Play Framework. You start learning from very simple example, and chapter after chapter you are more familiar with many aspects of Play. Its great book for beginners, but also a more advanced Play developers will find many interesting things. Ill expected a few more practical tips for a bigger applications, as Play is used in many places (from small to very complex), maybe some examples from real life (especially in chapter about Play in production). But it's good enough, and everyone could find something useful.

This book provides the necessary information to start developing with Play Framework. Although the some information is brief (chapters about Aktors, Working with Data), author covers all the major issues. As for me, chapter 10 (Debugging and Logging) and chapter 12 (production) contain a lot of useful information. The book is well structured and will be useful for understanding the basic principles of developing with Play Framework

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
