Hi community,  
as I’m a previous PHP and especially symfony programmer, I often try  
to find features of symfony in rails. Now I’m looking for a method  
which forwards to a 404 error page (but with stack trace and so on in  
development mode). I tried to manually render public/404.html, but if  
I do so, I miss the stack trace. Is there a method like this or are  
rails programmers using a different approach to show a 404 error ? I  
hope you understand my problem and help me solving it !

Thank you very much in advance,  
Christoph

In dev mode (or in production mode if you ask for it) if you don’t  
handle an exception you’ll get a stack trace etc… Is that what  
you’re looking for?

I don’t think anybody used it this way, since there  
is not much reason to do it. I won’t show a stack trace  
to my users in production, because that’s not their business  
and in development I get the debug info I need from  
development.log or the server output.

Maybe you don’t understand my question: I’m searching for a  
possibility to show a 404 error page, something like this code:  
redirect\_to\_404 unless request.xhr?  
Is there a method like redirect\_to\_404, or are rails developers using  
a different approach ?

render :file =\> “#{RAILS\_ROOT}/public/404.html”, :status =\> 404 and  
return

As weird as it may sound, there’s a whole section in the API that  
talks about this:  
[http://api.rubyonrails.com/classes/ActionController/Base.html#M000852](http://api.rubyonrails.com/classes/ActionController/Base.html#M000852)
