Starting Akka actors in Play

Question

I have a Play! application with some tasks I need to run periodically. I can schedule the tasks using Akka, but I am not sure how to start the scheduler itself. What I am doing right now is having a Scheduler object and starting it from `Global.scala`, like this ``` // app/jobs/Scheduler.scala package jobs import akka.util.duration._ import play.api.libs.concurrent.Akka import play.api.Play.current object Scheduler { def start() { Akka.system.scheduler.schedule(0 seconds, 1 minutes) { SomeTask.start() } } } ``` and then ``` // app/Global.scala import play.api._ import jobs.Scheduler object Global extends GlobalSettings { override def onStart(app: Application) { Scheduler.start() } } ``` The problem is that in this, the task runs even in development mode and during tests, that becomes soon very annoying. Is there a way to schedule jobs with Akka only in production mode?

Accepted Answer

Methods `isProd`, `isDev` and `isTest` on `Play` object could be helpful. Even if you doesn't have implicit `Application` in scope, you can pass it explicitly

```
override def onStart(app: Application) {
  if (isProd(app)) Scheduler.start()
}
```
