Rails - Jan 2006 - What is .Instance?

With observers, you have to do (according to AWDWR):

ItemObserver.Instance

What is ''.Instance''? I''ve looked in both the Rails
and Ruby docs and
don''t see any mention. I presume it''s like
''new''?

thanks

It''s a class method of ActiveRecord::Observer that instantiates the
observer and starts observing its classes.  You can use the observer
helper for controllers, however:

observer :people_observer
