Scala/Play: Assigning a value that's not there yet

Question

Say I have something like this:

case class User(id:Option[Long], name: String)

case class Account(id:Option[Long], userId: Long)

object Account {
    // apply method
    def apply(i: Identity): Account = {
        Account(None,SomeFutureUserId)
    }
}

This isn't working for some reason:

Account = Account(None,SomeUser.id)

How would I let Play! know that there will be a Long type in place of id? Something like a placeholder?

Answer 1

Try this:

case class User(id:Option[Long], name: String)

case class Account(id:Option[Long], userId: Option[Long])

object Account {
    // apply method
    def apply(i: Identity): Account = {
        Account(None,None)
    }
}
