What exactly you mean?

REST works fine with poly…  
Like this:  
map.resources :communities do |communities|  
communities.resources :comments do |comments|  
comments.resources  
end  
communities.resources :feeds  
end

Then you can use link\_to “New Comment”,  
new\_comment\_url(@community) restfully (with propriate actions!)
