Override Rails redirect_to flash messages to work with Twitter Bootstrap

bootstrap_flash_messages.rb

module ActionController
  module Flash
    protected
      def redirect_to(options = {}, response_status_and_flash = {}) #:doc:
        if alert = response_status_and_flash.delete(:alert)
          flash[:alert] = alert
        end

        if success = response_status_and_flash.delete(:success)
          flash[:success] = success
        end

        if info = response_status_and_flash.delete(:info)
          flash[:info] = info
        end

        if error = response_status_and_flash.delete(:error)
          flash[:error] = error
        end

        super(options, response_status_and_flash)
      end
  end
end

should be placed in Rails config/initializers/bootstrap_flash_messages.rb
