Play Framework PathBindable with Dependency Injection

由 为君一笑 提交于 2019-12-10 12:55:57
问题 I'm migrating a Scala Play application to 2.5 and am currently moving my components to dependency injection. There's one place left where I'm at a loss how to do it though. I have a PathBindable implicit conversion defined in the companion object: object Task { implicit def pathBindable(implicit stringBinder: PathBindable[String]) = new PathBindable[Task] { ... } } The implementation of the PathBindable needs to look up the object from a repository, but I haven't found a way to dependency

How to properly serve csv data with play framework

由 最后都变了- 提交于 2019-12-10 11:21:09
问题 I have a simple app which asks a DB a question, and then serves returns some data as simple text. The 'plain/text' response happens to be in CSV format. It gets read in by another program (matlab, through webread), and then we 'do analysis'. Now, it appears that the play framework has changed some settings. Whereas before this code; def singleEventsMultipleRegions(peril: String, region: List[String]) = Action.async { val theResult = db.run(filter(peril, region).result) val intermediate =

Slick: combine actions with a Seq of DBIOAction

由 两盒软妹~` 提交于 2019-12-09 18:24:08
问题 I have the (working) following code: val actions = (for { _ <- slickUsers.insertOrUpdate(dbUser) loginInfo <- loginInfoAction _ <- slickUserLoginInfos += DBUserLoginInfo(dbUser.userID, loginInfo.id.get) } yield ()).transactionally with loginInfoAction being a DBIOAction. I would like to change loginInfoActions to a Seq of DBIOAction and for each of them, execute the same DBUserLoginInfo action afterwards. I tried this stupidly: val actions = (for { _ <- slickUsers.insertOrUpdate(dbUser)
