I'm having real trouble with controller modules - they just don't seem to be getting picked up by Rails.

I've created two controllers via scaffold - Forum::ForumsController and Forum::TopicsController and neither works.

When I load /forum/forums in the browser, I get a routing error:

Recongnition failed for "/forum/forums"
The controllers are both where they should be in app/forum with correct file and class names.

Does anything else need to be done to get these working?
