I think that this should work, but I haven't tested it:
class Node extends KeyedMapper[String, Node] {
def getSingleton = Node
/* MAC address as primary key */
def primaryKeyField = mac
object mac extends MappedStringIndex(this, 17) {
override def writePermission_? = true
override def dbDisplay_? = true
}
}
Note that primaryKey_? is already set to true in MappedStringIndex.
writePermission_? is set to false by default...
