Hi.

I’m running some tests with Observers and I’m having trouble making them  
work.

I’ve tried to follow the code that’s on the API, but that does not work.

I’ve name my Observer after a model, as said, and added it in  
environment.rb. That does not work. I had to had it in application.rb,  
like observer :my\_observer to make it work. My problem is that that’s  
not very elegant…

Any ideas?

Thanks  
JotaPe

I’d guess you are running Rails 1.1.6 or earlier. Newer versions of  
Rails  
properly use the environment.rb for setting observers and have removed  
the  
ActionController::Base#observer call.

Yes, that’s a fact…
