Hi Ralph, Good question. Methods in controllers are considered actions only if they're connected to a url. Urls are connected to controller methods by using routes. The routes.rb file lists all of the routes that will connect urls to controllers and actions. In your routes, when you use map.connect (in Rails 1.x, 2.x) you directly connect a url to an action method. In Rails 3.0, this is done with match() instead of connect, but the idea is the same. If you use map.resources then you're connecting a whole slew of urls to a certain actions in your controller. Check the docs for details, but this is the "restful" style of URL handling, and means that these methods in your controller will become actions: index new create edit update show destroy Finally, be warned that in Rails 1.x and 2.x, when you generate a new Rails app, by default a pattern-match connector is written for you, exposing ALL of your methods as actions, which is probably not what you want. You should remove or comment those out. Jeff purpleworkshops.com -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
