Change plays default port doesn't work

This should do the trick: play '-Dhttp.port=9090' 'start 9090' or activator '-Dhttp.port=9090' 'start 9090' at least that was working some time ago, see this answer The behavior varies on exact Play version, anyway you need to test several versions (always with quotes) so finally you'll find the solution, unfortunately I...

If statements within Play/Scala JSON parsing?

The proper way to do this with JSON combinators is to use orElse. Each piece of the combinator must be a Reads[YourType], so if/else doesn't quite work because your if clause doesn't return a Boolean, it returns Reads[PlaylistItemInfo] checked against null which will always be true. orElse let's us combine...

In the Play Route's file, how can indicate to use routes from a module?

You do not need to check cookie in front-end, and actually you should not to it especially if you care for security. Your backend action should return ok() Result in case when everything's ok. If user is unlogged you can return unathorized() (Unathorized() in Scala). than in your jQuery you...

How to serve reactive ByteChunks in Play Framework (Java) v2.4.x

java,playframework,playframework-2.0,reactive-programming

Your getContentLength method is incorrect, because it returns negative lengths: MP3 size = 12000 from = 0 to = 5000 getContentLength = -4999 Fix this method and it should work. Apart from that, you should note that range and chunks are static fields, and you may face concurrency problems. Also...

Validate scala forms, when form contains inner case classes

forms,scala,validation,playframework-2.0

First things first, I'd get rid of the confirm_email and confirm_password fields since they're redundant in the Data model. After this operation, it'll look like this: case class Data( firstName: String, lastName: String, email: String, password: String) Next, your form mapping needs to be updated: val form = Form[Data]( mapping(...

Why we need implicit Application

scala,playframework-2.0,playframework-json

It's an architectural choice that was made by the developers. There are certain components of the framework that require a reference to an Application (typically the current running Application). The Cache, DB, Messages (i18n), Evolutions, and WS API are the first ones that come to mind. The Application trait is...

Filter a string before creating an Option[String]

If you already have an Option, and you don't want to use the value in certain cases, then filter is your most idiomatic choice: val one = Option("1") val zero = Option("0") one.filter(_ != "0") //Some("1") zero.filter(_ != "0") //None Using this method, your solution would be: (obj \ "approx_pieces").asOpt[String].filter(_...

Continuously-running code in Java Play! Framework

First the error java.lang.NoSuchMethodError: scala.Predef$.ArrowAssoc(Ljava/lang/Object;)Ljava/lang/Object; is not from Anorm but from Predef: the -> operator is not found to build tupple, which is quite weird. I would suggest to check your scala version and dependencies, to be sure there is not several scala lib pulled. Then if you want to...

Play Framework 2.x Ebean query ManyToMany for all

java,orm,playframework-2.0,ebean

Just use a RawSql query; once you start joining and adding lots of clauses, things get out of hand pretty quickly. At that point it gets really easy to write a query that's hard to debug and even harder to modify in the future. In the end, your query still...

Iterating cookies in Play+Java

java,cookies,playframework-2.0

You're reading cookies from the response, not the request. The response will only show cookies that you've set in the current request, since cookies are only sent in a response when you set them. If you want to see all the incoming cookies, you need to iterate over the cookies...

Typesafe Activator: “run” works, but “start” fails with an error

How does @Inject in Scala work

scala,playframework,dependency-injection,playframework-2.0

Looks close. Change val to var because it is not final and needs to be injected at a latter stage. @Inject var mailer: MailerClient = null I'd check also that the MailerClient library is mentioned as a dependency in the project configuration. You could try with WSClient instead as it's...

How to remove warning regarding the use of status code 200 with flashing in Play 2.3.7?

html,scala,playframework-2.0

Typically you would only use flash data with redirects, where you would otherwise not be able to render any data until the next request. And after that, the data is gone. For example, when the user logs out of my application, I might redirect them back to the login page,...

Generating a link to a controller action in Play Framework 2.3

The problem seems to be not the @routes syntax (which you have completely correct) but rather a case of the Twirl engine not seeing where code ends and HTML begins (or something like that anyway...) The line you've included, which has both a var and a semicolon, made me suspect...

Interchangeable menu in Scala Play

json,scala,validation,playframework-2.0

If you're applying loginMenu as an argument to main you don't need the @ in front of it, since you're already in a Scala code block. Try: @main("Welcome to Play", "Home")(loginMenu()) { <div class="container"> <h2>Home</h2> </div> } ...

How to keep Akka running all the time in Play 2.3

playframework,playframework-2.0,akka

The problem you are facing goes beyond development changes in files. You want your actor to be able to hold the state no matter what happens to the play application (maybe it failed for different reason?). Basically you want your scheduling actor to be persistent. It is very easy to...

Setting up play framework and dart for development and debug

eclipse,playframework-2.0,dart,dart-pub,typesafe-activator

I guess the best way is to use a proxy with rules to forward requests for Dart resources to pub serve and play resources to activator. This would be simple to build in Dart for example using shelf, shelf_route and shelf_proxy or nginx with a few forwarding rules.

Implicit conversion not taking place for Play Framework Lang in controller

scala,playframework-2.0,playframework-2.3

According to Play documentation If you have an implicit Request in the scope, it will provide an implicit Lang value corresponding to the preferred language extracted from the Accept-Language header and matching one of the application supported languages. So you need to change your action to def createView = Action...

Scala Play Forms verify that one date occurs after another

You can't reference other form fields within the same mapping until after they all successfully bind individually. That is, the constraint must be made on the outer mapping. val policyForm: Form[PolicyForm] = Form { mapping( "amount" -> of[Double].verifying(...), "beginDate" -> date("yyyy-MM-dd").verifying(...), "endDate" -> date("yyyy-MM-dd") )(PolicyForm.apply _)(PolicyForm.unapply _).verifying("End date has be...

Making it easier to create a Form object in Play Framework with ReactiveMongo

Play Action Async wrapping a Future

Action.async is not enough to make your code asynchronous. Here is the signature for async (I picked the simplest overload): def async(block: => Future[Result]): Action[AnyContent] It's up to you to provide that Future. If you're calling blocking code you can execute it concurrently like Future { blockingCode() }. However the...

Scala Standalone WS with Authentication

java,playframework-2.0,ebean

Well... that's because the Scala language promotes the idea of immutability, and hence Keeping this spirit WsRequestHolder is also kind of immutable. So... withHeaders does not mutate the current WsRequestHolder but returns a new instance of WsRequestHolder which has provided headers. Another reason for this kind of implementation is to...

Defining cross-attribute Json Validators for a case class in Play Framework 2.3.x (Scala)

Configure Play framework messages to not format numbers

java,playframework-2.0

In accordance with the documentation Play uses the MessageFormat class for formatting and it generates its output based on the provided Locale object. Hence, the thousand separator is used in your example. The simplest solution is to pass the string value instead the number. Messages.get("myerror.number", String.valueOf(5)); Play doesn't provide any...

What is data type of the input of withFormUrlEncodedBody?

So you'll need the following line in scope before creating an emailInvitationFormat: implicit...

Play framework: package javax.inject does not exist

JSON Reads combinator in Play scala 2.x doesn't work for Map[String, _]

You'd be a lot better off avoiding Map[String, Any], and Scala and Play make this easy.

Play 2.4, by default, generates a dependency injected router, unlike previously, when it used a static router.

Most likely it's connected with the fact that the routes object is generated during project compilation. After compilation, it should be placed under the target/scala-{ver}/src_managed directory. Mark this directory as source and IntelliJ should see routes correctly. You can use one of the following steps to do it: right-click the...

How to mock an Authenticator in play framework with guice injections?

java,playframework,playframework-2.0,guice,guice-3

A found a workaround. I just used an access method provided by Play framework 2.4 since it fully integrates Guice. Here is my Authentication Wrapper class: public class AuthenticatorWrapper extends Security.Authenticator { private final Security.Authenticator authenticator; public AuthenticatorWrapper() { authenticator = Play.application().injector().instanceOf(Security.Authenticator.class); } @Override public String getUsername(Http.Context ctx) { return...

How to chunk responses in Play without running out of memory

playframework,playframework-2.0,playframework-2.3

Unfortunately this is a limitation of Play's Java API in Play at the moment. There is no way in the Java API to get back pressure from the client, so it's easy to overwhelm the client. This will be fixed in Play 3 when we provide a better streams API...

Trouble understanding WS library in Scala

scala,asynchronous,playframework,playframework-2.0

It appears that you are calling WS inside the map block of collection.insert. That map expects that you return a play.api.mvc.Result, however WS.post with the map you have attached to it, returns a Future[play.api.mvc.Result]. Given that the Future.successful(BadRequest(Json.obj("message"->"Invalid email address"))) returns Future[play.api.mvc.Result] and your collection.insert returns a Future[Future[play.api.mvc.Result]] the common,...

Play Scala 2.4 linking asynchronous calls

The issue is with your types and that they don't match up with the required ones. .fold has to result in Future[Result] in both branches (the error and the success ones). In the successful form bind branch you have this: case (userData) => ... // The ... must evaluate to...

convert play framework route to java URL class (used to initialize java.net.URL class)

java,playframework,playframework-2.0

It has nothing to do with Play Framework. You want to play sound on the webpage directly from HTML (or with some Javascript). So you don't need Java for it (though your still can serve your .wav file from Play Framework as static asset). Check these links: w3schools.com/html/html5_audio.asp or stackoverflow.com/a/13402388/972676....

Play 2 - Access conf property in routes file

java,playframework,routes,playframework-2.0

First of all, I see absolutely no benefit from accessing vars in application.conf from the routes file. What's the difference between changing the value of a route in the routes file or .conf file. In both cases you need to change the value and restart the server for changes to...

Play: populating a helper select from Java

java,scala,playframework,playframework-2.0,template-engine

If you use LinkedHashMap as the implementation of Map you may keep the order of how objects were inserted. Shouldn't matter if using Scala's or Java's implementation. This class implements mutable maps using a hashtable. The iterator and all traversal methods of this class visit elements in the order they...

Play framework Json output issue

json,scala,playframework-2.0

As others have posted in the comments before, the type of the Map is not something which can be deserialized into Json by the framework, but you can easily get rid of the Map: scala> val s = "hello" s: String = hello scala> val list = List(1,2,3) list: List[Int]...

How to send a parameter to a custom action?

I am not sure about solution with ActionBuilder or ActionRefiner but that may work for you: def CachedAction(key: String, time: Duration)(f: Request[AnyContent] => Result) = { Action{ request => if(cache.contains(key)){ ... } else{ ... } f(request) } } and then: def myAction(p1: String) = CachedAction("hello" + p1, 100 millis){ request...
