hack to support post_url(@post)

usher.rb

require 'rubygems'
require 'usher'

# according to README should be:
#   Usher::Util::Rails.activate
# but above gives an error: vendor/plugins/usher/lib/usher/util/rails.rb:13: class definition in method body (SyntaxError)
# - so instead we load appropriate interface manually:

ActionController::Routing.module_eval "remove_const(:Routes); Routes = Usher::Interface.for(:rails23)"


# Monkey-patch to make Usher support usage like post_url(@post)

class Usher
  module Interface
    class Rails23

      def install_helpers(destinations = [ActionController::Base, ActionView::Base], regenerate_code = false)
        #*_url and hash_for_*_url
        Array(destinations).each do |d| d.module_eval { include Helpers }
          @router.named_routes.each do |name, route|

              def #{name}_url(options = {})
                options = {:id => options.id} unless options.is_a?(Hash) # if we receive an AR record, put it in :id param
                unless options.is_a?(Hash)
                  options = {:id => options}
                end
                ActionController::Routing::Routes.generate(options, {}, :generate, :#{name})

              end
