I've tried to implement a simple Observer to log changes to my objects. Whenever I try to enable the observer in my environment.rb, my application refuses to start.
Here's what's in my environment.rb:
Rails::Initializer.run do |config| config.active_record.observers = :audit_observer end
It seems, that rails can't find the plugins used in the observed models. This was a problem in older rails version (see http://dev.rubyonrails.org/changeset/4684), but I'm using rails 1.2.3, so this is already included.
As nearly all my models ar using some plugins, what can I do to get observers working?
Here's the mongrel output:
