Hello, I don’t know if this is a bug or a feature. When defining  
routes like:

map.resources :as, :has\_many =\> ‘bs’  
map.resource :b, :has\_many =\> ‘cs’  
map.resource :c

I get:

new\_b\_c GET /b/cs/new {:controller=\>“cs”, :action=\>“new”}

yet I want:

new\_b\_c GET /bs/:b\_id/cs/new {:controller=\>“cs”, :action=\>“new”}

which I get with adding:

map.resources :bs, :has\_many =\> ‘cs’

Is this supposed to be this way?  
Thank you, regards Christoph

I think you want to use map.resources, not map.resource, in all of  
those.
