I’ve read all the posts, blogs, peepcode about nested resources but I  
can’t get link\_to to work. I know I’m missing something simple so I  
hope another set of eyes will help out.

I have a pretty simple set up:

deliverable has\_many :roles

role belongs\_to :deliverable

here is what I have in routes.rb:  
map.resources :deliverables, :has\_many =\> :roles

from views/deliverables/show.html.erb I’m trying to provide a link to  
add a new role with this:

\<%= link\_to “+ Add Role”, new\_role\_url(@deliverable) %\>

But I get this error when rendering: undefined method `new\_role\_url’

I can type in the url [http://localhost:3000/deliverables/1/roles/new](http://localhost:3000/deliverables/1/roles/new)  
and it works fine so I’m stumped.

Thanks in advance for the help.

rails 2.0.2  
ruby 1.8.6

figured it out by checking out rake routes. should be:

\<%= link\_to “+ Add Role”, new\_deliverable\_role\_path(@deliverable) %\>
