Hi By default, rails engines do not support static assets in their own public/ directory. It is a so obvious feature that I had the prejudge in mind that it would not be trivial. I implemented a Rack middleware that looks in all the loaded plugins for a resource, if it can be served from there, it does it, if not, it forwards to the application (a simple overlay, just like the other parts of the engines work). Attached is the patch for review. This allows engines to have their own public/ directory with files, images, css files, etc. Just like with engines controllers and views, you need to have name conventions, as the names may clash. -- Duncan Mac-Vicar P. - Engineering Manager, YaST SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg)
