Rails: Skipping Base Class Filters in Subclasses

I encountered a case where we needed to skip a filter as it was causing infinite redirection in a subclass. I found my answer in: Rails Filters Documentation

Filter chain skipping

Declaring a filter on a base class conveniently applies to its subclasses, but sometimes a subclass should skip some of its superclass’ filters:

  class ApplicationController < ActionController::Base
    before_filter :authenticate
    around_filter :catch_exceptions
  end

  class WeblogController < ApplicationController
    # Will run the :authenticate and :catch_exceptions filters.
  end

  class SignupController < ApplicationController
    # Skip :authenticate, run :catch_exceptions.
    skip_before_filter :authenticate
  end

  class ProjectsController < ApplicationController
    # Skip :catch_exceptions, run :authenticate.
    skip_filter :catch_exceptions
  end

  class ClientsController  :index
  end
