I''m getting to the point now where I really need to start trapping the
errors.
So from my AWDWR book, I added the following directly from the book into
application.rb...
def rescue_action_in_public(exception)
case exception
when ActiveRecord::RecordNotFound, ActionController::UnknownAction
render(:file => "#{RAILS_ROOT}/public/404.html",
:status => "404 Not Found")
else
render(:file => "#{RAILS_ROOT}/public/500.html",
:status => "500 Error")
SystemNotifier.deliver_exception_notification(
self, request, exception)
end
end
end
and copied the file...app/models/system_notifier.rb changing the first
line ''pathname'' to the actual path to the base of my ruby
application
and then finally copied the file and folder for system_notifier...into
app/views/system_notifier/exception_notification
which includes the line...
<% require ''pp'' -%>
and I am thinking that this may be my problem - I am not sure. How do I
solve it?
if it matters, the complete trace of the error... (where line 54 is the
line immediately after the ''end'' of the ApplicationController
definition). Note that this error (development on webrick) differs
slightly from (production on Apache w/fcgi) but the net effect is the
same.

I see http://rails.rubyonrails.org/classes/ActionWebService/Container/ActionController/ClassMethods.html but it doesn''t make sense as to how I might implement and I am just taking this from the AWDWR book and it seemed to be ready for prime time. the http://books.pragprog.com/titles/rails/errata errata page has a note about this... ***** 464 #2298: I don''t know if this is a problem with Rails 1.0, Ruby 1.8.4, or something else entirely, but I could not get the rescue_action_in_public to load properly until I changed it. Ruby kept complaining that UnknownAction was an uninitialized constant. At first I just removed it, but that was unsatisfactory. In the end I had to change the case to use exception.class.name rather than exception, and list string constants instead of the actual class literals. Doing that made it work. I''m completely baffled about why this may be, but I''m a Ruby newbie as well as a Rails newcomer.--Jim Elliott ***** but I don''t know what ''string constants'' instead of the actual class literals means to me in this context. I know something is wrong, I don''t have the skill sets to make it right. I''m looking for a big hit with a clue stick. Thanks Craig

I inserted an extra ''end'' - you told me you thought I was missing an ''end'', I had one too many...that''s why I had to laugh, you thought I was one brick short of a full load, I had one too many bricks. I thought I would need 3 ''end'' lines, 1 for the ''def'', 1 for the ''case'' command and 1 for the ''when/else'' My fault - thanks If I could get the problem with ''unitialized constant UnknownAction'' problem, I would go to sleep very happy tonight.

Dave, As I explained in another thread, when you tried to reference any constant from the ActionController scope, Ruby tries to resolve this constant in ActionWebService::Container::ActionController module scope. This module is included by AWS during bootstrap process and happens to bear the same name. I didn''t dig this problem much, but I think it''s related to the black magic of const_missing that Rails uses. Kent.

yeah - I meant to say that... ;-) It actually was the same thread. I am rather surprised that there aren''t more people wondering about it - I am clearly not the only person to run into this problem (per the errata page). Perhaps many people aren''t motivated to trap their errors. Craig PS - thanks Kent...
