Create “Exception Filters” in Rails Using Execeptional

By Peter Cooper / December 3, 2006

Scott Fleckenstein has developed a plugin for Ruby on Rails called Exceptional that 'brings exception handling into the world of Rails filters'. The code speaks for itself on this one:

class SampleController <  ApplicationController
  handles AccessDeniedError,
    :with => :access_denied,
    :only => [:supah_sekret_akshun]

  def supah_sekret_akshun
    raise AccessDeniedError

  def access_denied
    render :text => 'no, u kant'

There's a bit more to it than that, so check out the official plugin site for examples and how to download the plugin.

    This sort of reminds me of Lisp's before, after, and around AOP stuff for the CLOS.

    I know there were some people yakking about AOP libraries on the Ruby List a long while ago... know of any developments in that area?

    Are you referring to AspectR? Unfortunately that page seems kinda old now, although I'm sure I heard something more recent about it..
