I was hitting the same problem. Enclosing the right part of the case in curly braces fixed the issue for me. This works for me: @user match { case Some(user) => { Welcome, @user.username! } case None => { <a href=”https://stackoverflow.com/questions/9748258/@routes.Application.login”>Login</a> } } Without the braces, it gave an error with the space after the … Read more
Try invalidating Intellij IDEA cache via File -> Invalidate Caches / Restart It takes like 5 minutes but did the trick for me.
PS: I wonder why Play Iteratees library has not been choosed by Martin Odersky for his course since Play is in the Typesafe stack. Does it mean Martin prefers RxScala over Play Iteratees? I’ll answer this. The decision of which streaming API’s to push/teach is not one that has been made just by Martin, but … Read more

Although there are different schools which one is better the most important is to make a 301 redirect from ‘wrong’ URL to the correct. … Read more
This is a very tricky business. SBT in Play is used for fetching dependencies, compiling source and templates, and for the SBT incremental compilation + auto-reloading feature. I have written a build.gradle script to resolve all Play 2.0 dependencies and set-up Eclipse or IntelliJ IDEA classpaths, and made it public here. I will try to … Read more
Occasionally after adding a view in Play 2.4.x, IntelliJ IDEA sometimes gets confused and absolutely refuses to build. Even rebuild Project fails: This still happens from time-to-time in IDEA 15. And when it does, the command line provides the quickest, most-reliable fix: sbt clean; sbt compile That’s it! IDEA will now compile the project as … Read more
You can access the current Appliction via play.api.Play.current() to find out the mode try play.api.Play.current().mode() or simply use play.api.Play.isDev(play.api.Play.current())
I just finished a prototype using Play 2.0 with Java and now am considering to learn Scala just so I can switch to it for further development. It’s not just the usual Java vs. Scala discussion – the problem as I see it with the Play framework is that it forces Scala idioms onto Java. … Read more
I’d argue that it’s generally a good idea to move from JSON-land to native-Scala-representation-land as early as possible. If obj is your JsObject, for example, you can write this: val subCategories = (obj \ “sub-categories”).as[List[Map[String, String]]] val names = subCategories.map(_(“name”)) Or even: case class Category(name: String, subs: List[String]) import play.api.libs.functional.syntax._ implicit val categoryReader = ( … Read more
