Hi,

lets say I defined the following resources:

map.resources :profiles

Is it possible to add a custom parameter just to one action via a  
block in the map.resources statement? I found the following solutions:

map.resources :profiles, :path\_prefix =\> ‘/  
profilecategory/:profilecategory\_id’

Problem here: It applies to every action, but I want it e.q. only for  
the ‘new’ action.

map.profile ‘/profile/:username’, :controller =\> ‘profiles’, :action  
=\> ‘show’

This works for one action, problem here: There still exists the route  
from map.resources to ‘show’, which would be something like ‘/  
profiles/:profile\_id’

Any suggestions?
