# == Triggering Observers
#
# In order to activate an observer, you need to call Observer.instance. In Rails, this can be done in controllers
# using the short-hand of for example observer :comment_observer. Or directly from Active Record, with
# ActiveRecord::Base.observer(:comment_observer).
# In order to activate an observer, list it in the <tt>config.active_record.observers</tt> configuration setting in your
# <tt>config/environment.rb</tt> file.
#
# config.active_record.observers = :comment_observer, :signup_observer
