Hi all,

I have a small question regarding Rails 3 / engines en routes file.

At this point, I start my routes file with the following line:

Rails.application.routes.draw do |map|

But, since Rails 3 RC 1, I got deprecation warnings in my app saying  
that Rails.application will become deprecated, using  
ProjectName::Application instead, but also that you need to drop the  
|map| parameter.

Now, that is in a project, but what about engines? Since engines are  
small sub applications that can be used in multiple apps, you can’t just  
use Projectname::Application.

Any comments on this issue?

Hi Michael,

Try using this instead:

Rails::Application.routes.draw do

I am using this with RC1 and get no warnings.

Cheers
