Return a mapped object using Slick - scala

Question

How can I return a mapped object using Slick? Using the following code my query returns List[(Int, String)] and not a List[Task] like I want it to. Is this not possible using Slick or am I thinking about Slick the wrong way is it not an ORM? I'm trying to return a query and use it in a view template using the Play2 framework. I'd like to end up accessing the objects like task.id task.label etc... Thanks.
import play.api.Play.current
import play.api.db._
import scala.slick.driver.H2Driver.simple._
case class Task(id: Int, label: String)
object Task extends Table[(Int, String)]("TASKS") {
lazy val database = Database.forDataSource(DB.getDataSource())
def id = column[Int]("ID", O.PrimaryKey, O.AutoInc)
def label = column[String]("LABEL")
def * = id ~ label
def all() : List[Task] = database.withSession { implicit db: Session =>
Query(Task).list
}
}

The issue is with how you defined your table. Try changing your table definition to:
case class Task(id: Int, label: String)
object Task extends Table[Task]("TASKS") {
lazy val database = Database.forDataSource(DB.getDataSource())
def id = column[Int]("ID", O.PrimaryKey, O.AutoInc)
def label = column[String]("LABEL")
def * = id ~ label <> (Task.apply _, Task.unapply _)
def all() : List[Task] = database.withSession { implicit db: Session =>
Query(Task).list
}
}
The difference is that the type param I am passing to the Table is Task instead of (Int, String). This should fix your issue.
