Getting autoincrement values with Slick library in Scala

Question

How do I get the auto-incremented values for records inserted with Slick? The following code prints 1111. I would have expected it to print 1234

import scala.sli         


        

Answer 1

According to SLICK Inserting document, you should define a method forInsert looks like:

def forInsert = first ~ last <> (
    { t =>
        User(None, t._1, t._2)},
    { (u: User) =>
        Some((u.first, u.last))
    }) returning id

To get result:

def save(user: User): User = {
    val id = users.forInsert.insert(user)
    new User(Some(id), user.first, user.last)
}
