Allowing access to a Rails URI with CanCan and Devise

We're migrating capabilities to a centralized location, which happens to be Rails based. All of the resources are protected with CanCan and Devise, but I needed a single controller method to not be protected.

Disabling the CanCan portion was easy:

skip_authorize_resource :only => :uri

Disabling Devise took a bit more work:

skip_before_filter :authenticate_user!, :only => :uri

Now, requests to the :uri method won't need to be authenticated.
