问题 I'm trying to use CKEditor in a Rails 3.1 app. I have the ckeditor directory in app/assets/javascripts/ckeditor/, with extraneous stuff like the uncompressed and modularized source removed. It works fine in development. In production or staging environments, ckeditor can't find it's own files: config.js, lang/en.js skins/kama/editor.css. I can see that these files are not being precompiled, which makes sense since the asset pipeline by default won't include or precompile anything that matches
