Rails 2.1.0 monkey patch to add the recognized or matched rails route to the request

robd (Rob Dupuis) — Fri, 25 Jul 2008 15:10:27 GMT

This was based on code I found here from Chris Cruft - http://cho.hapgoods.com/wordpress/?p=151

Enhanced to support rails 2.1.0 and also allows alias method chains for recognize from other plugins still to work.



module ActionController

  class AbstractRequest

    attr_reader :recognized_route

    

    def init_recognized_route_from_path_parameters

      recognized_route = path_parameters.delete(:recognized_route) 

    end

  end



  module Routing

    

    class RouteSet

      def recognize_with_route(request)

        result = recognize_without_route(request)

        request.init_recognized_route_from_path_parameters

        result

      end

      alias_method_chain :recognize, :route



      def write_recognize_optimized_with_route

        tree = segment_tree(routes)

        body = generate_code(tree)

        instance_eval %{

          def recognize_optimized(path, env)

            segments = to_plain_segments(path)

            index = #{body}

            return nil unless index

            while index < routes.size

              result = routes[index].recognize(path, env) and result[:recognized_route] = routes[index] and return result

              index += 1

            end

            nil

          end

        }, __FILE__, __LINE__

      end

      alias_method_chain :write_recognize_optimized, :route



    end

  end

end

Code to disable YUI calendar previous and next month links icons

This solution does not require modifying the yui source and works on YUI version 2.5.0. It will disable the next and previous arrows based on the out of bounds dates you specify with mindate and maxdate when you configure the calendar. Requires YUI dom and a namespace called your_app.

1) attach an onRender event when you configure the calendar and before you call render

calendar.renderEvent.subscribe(YAHOO.your_app.calendar().initArrows, calendar);

2) add the following function:



YAHOO.your_app.calendar = function() {

	

	var addDays = function(date, days) {

		return YAHOO.widget.DateMath.add(date, YAHOO.widget.DateMath.DAY, days);

	};

	

	var showPreviousArrow = function(cal) {

		return showArrow(cal, cal.toDate(cal.cellDates[0]), 1);

	};



	var showNextArrow = function(cal) {

		return showArrow(cal, cal.toDate(cal.cellDates[cal.cellDates.length-1]), -1);

	};

	

	var showArrow = function(cal, startingDate, step) {

		if (!cal.isDateOOM(startingDate)) { //ie not overlapping

			return !cal.isDateOOB(addDays(startingDate, (-1 * step)));

		}

		for (var i=0; (i * step) < 7; i += step) { //iterate forwards for previous month check, backwards for next month check

			var date = addDays(startingDate, i);

			if (!cal.isDateOOM(date)) { //shortcut exit; as soon as we find an in month date we can supress the arrow

				return false;

			} else if (!cal.isDateOOB(date)) {

				return true;

			}

		}

		return false;

	};

	

	return {

		initArrows: function(type, args, cal) {

			if (!showPreviousArrow(cal)) {

				hideArrow(cal, cal.Style.CSS_NAV_LEFT);

			}



			if (!showNextArrow(cal)) {

				hideArrow(cal, cal.Style.CSS_NAV_RIGHT);

			}

		}

	};

};
