Preferred method for named routes in a single, non-resource controller?
## Option A

root :to => 'search#index', :as => 'search'
get :users, :as => "search_users"

end

Determine object from restful / polymorphic routes, taking into account the possibility that to_param has been overridden for the given object's class.
cls = controller_name.classify.constantize
paramtest = cls.new
paramtest.attributes.map{|name,val| paramtest[name] = name }
to_param = paramtest.to_param
@object = cls.send("find_by_#{to_param}", params[:id])
