Hi -- I''m upgrading an app from Rails 2.0.2 to 2.3.5 in development on a Mac OS/X Leopard. I unfroze the old Rails files, froze the 2.3.5 gem on the machine into the app, and some quick tests of the app showed no problems. However, after trying to run rake db:migrate, it fails silently. Run with trace I get the output below. I gather it might be related to plugin initialization or

Greetings all, As a Noob, I''ve been diligently working my way through the AWD4R book and finally arrived at the part about observers -- which BTW I think are very cool tech. Anyhow, I got the Audit Observer working. Now I want to test it and perhaps examine it''s attributes and methods to make sure it does what is expected of it. For example, one thing I would like to do

Hello all! I''m having an issue with Observers, and I''m hoping someone knows the answer.

I was just wondering what about a report that I made almost 2 months ago: Active Record observers broken<https://rails.lighthouseapp.com/projects/8994/tickets/4087-activerecord-observers-cant-be-used-for-before-callbacks> I think it''s a pretty big bug.
