Database transactions in Play framework scala applications (anorm)

Question

I am developing an application using Play framework and scala. I am using anorm for data-access layer. And I\'ve got a problem I could not solve.

Brief:

Answer 1

What about

class Dao {
  def foo(id: Long)(implicit connection: Connection) = {
    SQL("select * from foo where id={id}").on('id->id).as(...)
  }
}

class Service{
  def withConnection = {
    DB.withConnection {implicit connection =>
      Dao.foo(1)
      Dao.foo(2)
    }
  }

  def withTransaction = {
    DB.withTransaction {implicit connection =>
      Dao.foo(1)
      Dao.foo(2)
  }
}
