How do you update multiple columns using Slick Lifted Embedding?

Question

How do you update multiple columns using Slick Lifted Embedding ? This document doesn't say much.

I expected it to be something like this

Query(AbilitiesTable).filter((ab: AbilitiesTable.type) => ab.id === ability_id).map((ab: AbilitiesTable.type) => (ab.verb, ab.subject)).update("edit", "doc")

Answer 1

With recent versions of Slick, this way of writing it works:

Users.filter(_.id === filterId)
     .map(x => (x.name, x.age))
     .update(("john", 99))

Be careful to remember the extra parentheses if you are updating more than one property otherwise you might get a compiler warning.

Answer 2

I figured it out. It should be like this

val map = Query(AbilitiesTable)
  .filter(_.id === ability_id)
  .map(ab => ab.verb ~ ab.context)

map.update(("", ""))

Typesafe, why your documentation is so bad ? I have to Google pretty much every silly thing or dig through unit-tests for hours. Please improve it. Thanks.
