Help - building a simple user dashboard

hi,

im trying to find the simplest way of bulding a user dashboard.
currentyl
using namespace like this:

resource :dashboard, to: ‘dashboard#index’, as: 'dashboard’do
resources :vehicles , to: ‘vehicles#index’
end

controller action is using its own layout file (one yield section), but
now i need to rename all link_to’s accordingly.

how can i build a simple dashbaord so i can reuse all resources within
without changing them?
(should be as simple as the application-layout, …)

thx
