如何在Ruby中使用sass-rails帮助器? [英] How to use sass-rails helpers in Ruby?

问题描述

在 Github页面中，似乎可以使用Sass帮助器(asset_path ，asset_url，image_path等)，但我不知道怎么做.

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.

我需要为Paperclip附件设置default_url，并要使用资产管道中的其中一项资产.

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.

推荐答案

您可以在SCSS文件中使用sass帮助器，但不能在其他地方使用它们.在这些情况下，您需要使用常规的asset_path和image_tag帮助器.

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.
