scss.erb ruby​​ 代码未执行 [英] scss.erb ruby code not executing

问题描述

我正在尝试加载存储在我的样式表文件中 Rackspace 的 CloudFiles 上的背景图像.我用雾&CarrierWave 上传图像文件并调用该文件.我不断收到此错误:

I am trying to load a background image which is stored on Rackspace's CloudFiles in my Stylesheet file. I used Fog & CarrierWave to upload the image file and to call the file. I keep on getting this error:

"...und-image: url(": expected ")" 之后的 CSS 无效，是 "<%= design.main..."

Invalid CSS after "...und-image: url(": expected ")", was "<%= design.main..."

preview.css.scss.erb:

preview.css.scss.erb:

html{
     background-image: url(<%= design.main_image_url.to_s %>);
}

<小时>

更新:我改写了我的问题，我从这里得到了答案

我应该问的是如何将实例变量传递给资产?"- 你不能

What I should have ask was "How to pass an instance variable to assets?" - Which you can can't

推荐答案

将 url 放在引号中.

Put the url in quotes.

url('<%= design.main_image_url.to_s %>');
