I am attempting to use the Observer feature in ActiveRecord to monitor a set of objects. My observer is not named after the objects it is monitoring (because it is monitoring more than one object) so I have the following in my environment.rb:
Rails::Initializer.run do |config| config.active_record.observers = :message_observer end
My observer looks something like this:
class MessageObserver < ActiveRecord::Observer observe Topic, Comment
def after_create(message) ...code to handle event... end end
My problem was that the observer was not firing. After extensive debugging I have determined the problem. If I start up my development environment (Webrick) I have verified the observation is setup correctly and my observer is observing the correct models when the first request is made. When I make a second request the observation is no longer setup and therefore my observer does not fire. So if in the first request I carry out the action that triggers the observer everything works fine. But every request after that fails.
I am guessing the problem has something to do with the automatic reloading of the models during the development environment. So my question is how do I fix this?
