# Better each() for use with coffeescript
# 1. Wraps child in jquery object
# 2. Sets child first argument, so that fat-binding can be used.
# 3. Sets @ as well, for normal binds
jQuery.fn.loop = (block) ->
  for i in @
    element = jQuery(i)
    res = block.call element, element
    break if res == false

class ApplicationController < ActionController::Base

  ...
  #Problem:
  #In rails 3.0.1+ it is no longer possible to do this anymore;
  #  rescue_from ActionController::RoutingError, :with => :render_not_found
  #
  #The ActionController::RoutingError thrown is not caught by rescue_from.
  #The alternative is to to set a catch-all route to catch all unmatched routes and send them to a method which renders an error
  #As in http://techoctave.com/c7/posts/36-rails-3-0-rescue-from-routing-error-solution
