HEROKU ROR server - problem with css files

Hi,

I've created simple ROR app and commit it to HEROKU server. When I
change
config.assets.enabled = true
and put 'false' then it works but doesn't use my .css styesheets.

In case config.assets.enabled = true it doesn't work...

How can I fix it?

As far as I understand the documentation, it has to be hosted on the cedar-stack, but the standard bamboo-stack does not support the asset pipeline.

According to this article http://devcenter.heroku.com/articles/rails31_heroku_cedar I would guess that you have to recreate your application or try to convert the stack.
