Assume these two simple queries: def findById(id: Long): Option[Account] = database.withSession { implicit s: Session => val query = for (a <- Accounts if a.id === id) yield a.* query.list.headOption } def findByUID(uid: String): Option[Account] = database.withSession { implicit s: Session => val query = for (a <- Accounts if a.uid === uid) yield a.* query.list.headOption } I would like to rewrite it to remove the boilerplate duplication to something like this: def findBy(criteria: ??? => Boolean): Option[Account] = database.withSession { implicit s: Session => val query = for (a <- Accounts

We have a MySQL table containing several boolean columns which specify the roles a user may have. Is it possible with slick's lifted embedding to write a type mapper which combines & transforms these multiple columns to one field in the case class User like shown below? case class User(id: Option[Int], nickname: String, role: Seq[Role.Role]) object Users extends Table[(User)]("ask_user") { def id = column[Int]("id", O.PrimaryKey, O.AutoInc) def nickname = column[String]("nickname") def is_editor = column[Boolean]("is_editor") def is_moderator = column[Boolean]("is_moderator") def is

I am using slf4j-simple in my project. I would like to change logging level for slick to INFO. After reading Logging options for Slick and Class SimpleLogger docs I have tried to add following options to my VM line: -Dorg.slf4j.simpleLogger.defaultLogLevel=INFO -Dlogger.scala.slick=INFO -Dlogger.scala.slick.jdbc.JdbcBackend.statement=INFO -Dorg.slf4j.simpleLogger.log.scala.slick=INFO I see a few INFO level logs comming from jetty, therefore the basic logging seems to be working. I am also able to change level of logs shown by using -Dorg.slf4j.simpleLogger.defaultLogLevel=TRACE , but even that

I have my custom authenticated action that is like def Authenticated(rights: String*) = new ActionBuilder[MyAuthenticatedRequest] { *** } In my controller I use this action to check the user has the right to view the page def password = Authenticated(UserRights.USER) { implicit request: MyAuthenticatedRequest[_] => Users.findById(request.account.id) match { case Some(user) => Ok(views.html.settings.password(frontUser, user)) case _ => NotFound } } My oject Users uses slick to retrieve the user in the database def findById(id: Long)(implicit s: Session): Option[User] = users.where(_.id === id)

I started to use Slick 3.0.0 and I like it's succinct syntax. Nevertheless, I wasn't able to find a way to use it in a database agnostic way. In the following example provided in the documentation: http://slick.typesafe.com/doc/3.0.0/gettingstarted.html I'd like to be able to decouple somehow this code of the database used and avoid importing database specific in my code (i.e slick.driver.H2Driver.api._ ). I tried to get rid of it by providing the connection using the cake pattern, but the ".result" member isn't available then. A workaround would be to import slick.driver.JdbcDriver.api._ ,

I use flowing code for upsert list items case class Item(id: String, text: String) class Items(tag: Tag) extends Table[Item](tag, "items"){ ... } val tbl = TableQuery[Items] def insertItems(items: List[Item]):Future[Int] = { val q = DBIO.sequence(items.map(tbl.insertOrUpdate).toSeq).map(_.sum) db.run(q) } For items list with length 2000, upsert takes ~10 seconds. It's too long... I think, most part time takes compiling queries. How should I rewrite insertItems for acceleration it? Use compiled queries ( docs ). AFAIK, Compiled queries for insert are available after slick 2.0. Also, to insert a
