Hey people,

I’m having a problem implementing global error handling in Rails.

I using the Rails bible\*, and on page 464 it has some code for  
implementing  
email notification of such errors via the rescue\_action\_in\_public method  
globally in application.rb. I’ve implemented it, but I’m seeing this in  
my  
logs

NameError (uninitialized constant  
ActionWebService::Dispatcher::ActionController  
::UnknownAction):  
/usr/local/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active\_support/dep  
endencies.rb:100:in `const_missing' /app/controllers/application.rb:14:in`rescue\_action\_in\_public’  
/usr/local/lib/ruby/gems/1.8/gems/actionpack-1.12.5/lib/action\_controller/re  
scue.rb:33:in `rescue\_action’

And I’m getting “Application error (Rails)” in the browser.

Any suggestions?

Thanks,  
Mike
