(Rails 3) Is it possible to hardcode ids in a named route?

As far as I know, the following is the encouraged way to create a simple named route in Rails 3:

match 'sign-in' =>开发者_开发技巧 'sessions#create', :as => :sign_in

Is there a clean way to hardcode an id (or any parameter) in a named route? For a silly example:

match 'first-user' => 'users#show', :as => :first_user, :id => 1

Did you try that? It just works like that.
