I’ve got a ‘map.resources :ultra\_things’ in my routes.rb, and in a  
view I have…

\<%= link\_to @ultra\_thing.name, ultra\_thing\_path(@ultra\_thing.id) %\>

And this all works very, very well… in development.

However, on the production server I get an error in the log…

(undefined method `ultra\_thing\_path’ for #\<#Class:0xb7504050:  
0xb7504028\>) on line #5 of app/views/ultra\_things/list.rhtml

They’re both using the exact same code (deployed from trunk with  
capistrano). They’re both running on the same version of Rails  
(1.2.3).

What the \*\*\*\* am I missing? I running out of hair fast here.
