What is .Instance?

Rails

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’?

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
