From the Github page it would seem that one can use the Sass helpers (asset_path, asset_url, image_path etc.) in Ruby but I can’t figure out how.
I need to set the default_url for a Paperclip attachment and want to use one of my assets from the asset pipeline for that.
You can use the sass helpers in SCSS files, but you cannot use them elsewhere. In those cases you need to use the regular asset_path and image_tag helpers.
