问题 I closed the terminal window by mistake and I don't know the PID of the running Play process. How to find it? Or, where is the RUNNING_PID file? I am using Play 2.4.6 and running in non-production mode ( activator run ). 回答1: When using dev mode ( activator run ), no RUNNING_PID file is generated. The process won't detach and will be killed when the terminal is closed. By default the RUNNING_PID file is written to ./target/universal/stage/RUNNING_PID (inside the project's root directory) when

问题 In PlaySlick sample there is file with sample data access object. https://github.com/playframework/play-slick/blob/master/samples/basic/app/dao/CatDAO.scala and table definition: private class CatsTable(tag: Tag) extends Table[Cat](tag, "CAT") { def name = column[String]("NAME", O.PrimaryKey) def color = column[String]("COLOR") def * = (name, color) <> (Cat.tupled, Cat.unapply) } Is it possible to generate a new table using this definition without using play evolutions?

问题 I can run a single selenium test in play's browser UI, however, is it possible to execute a play selenium test on the command line? Obviously if I run play auto-test it will execute all my selenium tests (as well as my junit tests). Is there a way that I could tell Play to execute just a single selenium test on the command line to check whether it works using the headless browser? 回答1: I don't think it's possible to do so with the current play framework, but see how auto-test works on https:/

问题 Scala Execution Context and Dispatchers - Listing and comparison: Why ? There are a lot of questions around what/how/what is the best Execution Context to use to execute futures on in Scala and how to configure the dispatcher.

问题 I'm migrating some of my services from Play 2.7.x to the newest 2.8.2, together with scala 2.13.2 and sbt 1.3.12. I'm hitting an obstacle with the play-json though, and the Reads[A] I have the following setup: sealed trait Charge {} case class ChargeOne(one: Int) extends Charge case class ChargeTwo(two: Int) extends Charge object Charge { implicit val writes: Writes[Charge] = (charge: Charge) => {...} } We have some tests looking like so val chargeOne = ChargeOne(1) val json = Json.toJson

问题 Given the following JSON: { "field1": "value1", "field2": "", "field3": "value3", "field4": "" } How do I get two distinct JSONs, one containing the fields with value and another one containing the fields without value? Here below is how the final result should look like: { "field1": "value1", "field3": "value3" } { "field2": "", "field4": "" } 回答1: You have access to the JSON object's fields as a sequence of (String, JsValue) pairs and you can filter through them. You can filter out the ones
