After filters are not called when exception occurs

Please note after filters are not executed when an exception occurs. You have to handle these situations explicitly.

:only, :except and passing in multiple parameters

To specify that the filter should be applied to or excluded from given controller actions, use the :only and :except parameters. To pass in multiple controller actions use an array:

after_filter :authorize, :except => [:index, :show]
after_filter :authorize, :only => :delete
