Hi,

I’ve installed restful\_authentication, added the line:  
config.active\_record.observers = :user\_observer

and run:  
script/generate authenticated user session --include-activation

but I get the following error:  
/usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/  
active\_support/dependencies.rb:266:in `load\_missing\_constant’:  
uninitialized constant UserObserver (NameError)

Am I missing something?  
My config is:  
Ruby 1.8.6  
Rails 1.2.4

Regards  
Paul

Is there a user\_observer.rb file in the model directory containing a  
UserObserver class? The generator usually creates one.

I had this problem:

I think its because you’ve got acts\_as\_authenticated and  
restful\_authentication installed. Remove acts\_as\_authenticated and  
rerun the generator. At least that’s what worked for me.
