Difference between :as option in Rails 2 and Rails3 routing? -

-

in rails 2.x have: 

 map.resources :posts, :controller => 'posts', :as => 'articles'

this creates alias our posts routes. example, sends "domain.com/articles/" posts controller index action.

in rails3, however, :as option behaves differently. example:

 resources :posts, :controller => 'posts', :as => 'articles'

sets named route rather alias, , going "domain.com/articles/" gives error:

no route matches {:controller=>"posts"}

how old (rails 2) :as behavior using new (rails 3) api?

ps: please don't tell me rename controller. that's not option me.

from cursory reading of ror guide on routing, think might need try:

resources :articles, :controller => "posts"

(http://guides.rubyonrails.org/routing.html#specifying-a-controller-to-use)

you might need add :as => "articles", named helper might set since adding :articles resources.
