Play Framework Anorm withConnection Error - scala

Question

I have the following case class and class in Play Framework 2.5. Since the DB object has been deprecated I'm trying to use the new dependency inject methodology but not understanding why my code does not compile. The old method works fine, the new method has compilation error.
missing parameter type on the implicit connection =>
package models
import javax.inject.{Inject, Singleton}
import play.db._
import anorm.SqlParser._
import anorm._
import play.api.db.DB
import play.api.Play.current
case class Department(id: Int,
name: String)
#Singleton
class DepartmentDao #Inject() (dBApi: DBApi) {
private val db = dBApi.getDatabase("default")
val simple = {
get[Int]("department.id") ~
get[String]("department.name") map {
case id ~ name => Department(id, name)
}
}
def getDepartments = DB.withConnection { implicit connection =>
SQL("SELECT * FROM DEPARTMENT")
}
def getDepartmentsNew = db.withConnection { implicit connection =>
SQL("SELECT * FROM DEPARMTMENT")
}
}
UPDATE:
I've placed what the code looked like before was I was originally trying to get it working. Unless I am missing something this code should run. It is identical to code I've seen in multiple sample projects.
#Singleton
class DepartmentDao #Inject() (dBApi: DBApi) {
private val db = dBApi.getDatabase("default")
val simple = {
get[Int]("department.id") ~
get[String]("department.name") map {
case id ~ name => Department(id, name)
}
}
def getDepartments: Seq[Department] = db.withConnection { implicit connection =>
SQL("SELECT * FROM DEPARMTMENT").as(simple.*)
}
}
