First, the new way to write this plugin is:
module Sequel
module Plugins
class MyPlugin
class InstanceMethods
def before_save
super
self.updated_at = Time.now
end
end
end
end
end

Yes:
class Monkey < Sequel::Model
plugin :my_plugin
def before_save
super
self.name += " after"
end
end
If you have hooks defined by plugins or superclasses, just call
super. It's not a bad idea to always include it, so you don't forget
to when you add a plugin later.
