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

You can retrieve the generated value like this.

Add autoInc method to Users object.

def autoInc = id.? ~ first ~ last <> (User, User.unapply _) returning id

Use Users.autoInc.insert instead.

print(Users.autoInc.insert(User(None, "Jack", "Green" )))
