Ok, just to clarify a bit more, as Marnen said, a template is not mandatory, is just the default. Take a look a this example: http://pastie.org/638500 I took it for some book and modified it just a bit. With format html, it will search for the default export.html.erb template, but for csv, it will behave differently. The example here uses fastercsv, which will let you handle csv in a nice way, but nevermind it for now, you should asume that you'll have a variable with the csv data you want to return, and you'll return it with the send_data method (you can chech de ri doc for this later), setting the content-type and suggesting a file name to be saved. So my point here is to show you how you can answer from an action without having a template and considering more that one format. Anyway, it seems that you're focusing on the wrong thing, you should read more about ActionController (ri doc or the guide on the ruby on rails site should be fine), this is not a routing problem.
