Upgrading to Rails 3: You are using the old router DSL which will be removed in Rails 3.1

You upgraded your Rails 2 application to Rails 3, you changed all the routes to match the new Rails 3 syntax, but Rails is still throwing the following deprecation message.

DEPRECATION WARNING: You are using the old router DSL which will be removed in Rails 3.1. Please check how to update your routes file at: http://www.engineyard.com/blog/2010/the-lowdown-on-routes-in-rails-3/. (called from /Users/weppos/Sites/working/simonecarletti/config/routes.rb:1)

The solution is really straightforward, just around the corner, but you need to be good enough playing "spot the difference" game. If you're not, here's the trick.

Make sure the #draw</code> block at the beginning of yourroutes.rbfile doesn't yield any|map|` parameter. In fact, this statement will cause the warning

Simonecarletti::Application.routes.draw do |map|

while this one won't.

Simonecarletti::Application.routes.draw do

Needless to say, remove the map parameter only when you wiped out all the legacy routes. Otherwise your application won't work at all.
