Greetings, I''m a newby to both "R"s in RoR. I would like to use Builder::XmlMarkup to generate my pages. If there is a working downloadable example somewhere, that would probably be enough.

Hi folks, Thanks to the community feedback on the 1st version, I''ve come up with a much improved version of the acts_as_taggable mixin. There´s some piece of the action here: http://dema.ruby.com.br/articles/2005/09/03/tagging-on-steroids-with-rails Cheers Dema -- http://dema.ruby.com.br - Rails from a .NET perspective

This is a weird one: My app works fine on our local box with webrick. After uploading to TxD server, the app starts behaving weirdly. I make some edits to one of the controllers and my changes don''t seem to be going through. So I go ahead and change the name of the controller file. The page loads without error.

...include any javascript or CSS files whose name matches the current controller''s name. In addition, any file named like ''controller_name_action_name.css'' will also be included for specific actions (likewise for JS). It was inspired by a portion of code I saw from Demetrius Nunes. To use it, put the following in your application.rb: class ApplicationController < ActionController::Base helper ''require_resource'' end Then in my layout''s HTML "head" section: <%= stylesheet_auto_link_tags %> <%= javascript_auto_in...

Hello! I''m looking for assistance EXTENDING an example from the Agile Web Development With Rails book: Composing Data with Aggregation (page 324).
