copied!<p>There have been changes in play 2.2 to make it easier to compose actions. The resource you are referring to is outdated. </p> <p>Instead you should create a custom action builder by extending ActionBuilder to create your action, this will get you all the fancy apply methods you may need (including async support and all)</p> <p>For example you may do : </p> <pre><code>trait MyAction extends Results{ class MyActionBuilder[A] extends ActionBuilder[({ type R[A] = Request[A] })#R] { def invokeBlock[A](request: Request[A], block: Request[A] => Future[SimpleResult]) ={ // your authentication code goes here : request.cookies.get("loggedIn").map { _=> block(request) } getOrElse Future.successful(Unauthorized) } } object MyAction extends MyActionBuilder } </code></pre> <p>which you can then use as such : </p> <pre><code>object MyController extends Controller with MyAction{ def authenticatedAction=MyAction { Ok } def asyncAuthenticatedAction=MyAction.async { Future.successful(Ok) } def authenticatedActionWithBodyParser = MyAction(parse.json){ request => Ok(request.body) } } </code></pre> <p>For brevity's sake I used a very trivial authentication mechanism you will want to change that :) </p> <p>Additionally, you can create a custom "request" type to provide additional information. For instance you could define a AuthenticatedRequest as such : </p> <pre><code> case class AuthenticatedRequest[A](user: User, request: Request[A]) extends WrappedRequest(request) </code></pre> <p>Provided you have a way to get your user such as </p> <pre><code> object User{ def find(s:String): Option[User] = ??? } </code></pre> <p>Then change your builder definition a bit as such </p> <pre><code> class MyActionBuilder[A] extends ActionBuilder[({ type R[A] = AuthenticatedRequest[A] })#R] { def invokeBlock[A](request: Request[A], block: AuthenticatedRequest[A] => Future[SimpleResult]) ={ // your authentication code goes here : (for{ userId <- request.cookies.get("userId") user <- User.find(userId.value) }yield { block(AuthenticatedRequest(user,request)) }) getOrElse Future.successful(Unauthorized) } } </code></pre> <p>Your controller now has access to your user in authenticatedActions: </p> <pre><code>object MyController extends Controller with MyAction{ val logger = Logger("application.controllers.MyController") def authenticatedAction=MyAction { authenticatedRequest => val user = authenticatedRequest.user logger.info(s"User(${user.id} is accessing the authenticatedAction") Ok(user.id) } def asyncAuthenticatedAction = MyAction.async { authenticatedRequest=> Future.successful(Ok(authenticatedRequest.user.id)) } def authenticatedActionWithBodyParser = MyAction(parse.json){ authenticatedRequest => Ok(authenticatedRequest.body) } } </code></pre>
