Let's say that I would like to update db columns from
case class Link(url:String, auther: String)
to
case class Link(url:String, auther: String, created: DateTime)
However, I don't want to drop the table and create it again with DropAllCreate
, because I would like to preserve my data.
How are we supposed to do it in SORM? or the only way is to do manual migration with SQL?
Yes. Manual altering is the only way.
