R – Why is link_to not taking me where I want it to

I have a model 'Asset' and, on the show page, I have this:

{ :controller 'looks', :action => 'whatever' } %>

The 'looks' controller and 'whatever' action both exist.

Now when I go the the show page for the second Asset and click the test link I get this error:

Rendering rescues/layout (not_found)

So apparently it's directing me to an action that's named whatever asset_id whose show I came from. If it helps, I'm using the authlogic and compass gems. I'd appreciate any help.
