right, so now what you need to do is use the current user in the action to map it to the user relationship in some way.
The long way:
change fn changeset, context ->
Ash.Changeset.change_attribute(changeset, :user_id, context.actor.id)
end
The built in way:
# relate the actor to the `:user` relationship of this record.
change relate_actor(:user)
