Rails 4 - 生产图像和字体不指向指纹

Question

我将自定义主题导入到主页的Rails应用程序中。我已将整个文件夹复制到app/assets/customlibrary中，这样我就不必拆分主题文件了。

当我在生产环境中运行我的应用程序时，Rails在app/assets/customlibrary/*中被引用时无法找到指纹资产 app/assets/customlibrary/css/style.css。

例如，在style.css中，background: url("../images/hero-image.jpg")会产生GET http://localhost:3000/assets/images/hero-image.jpg 404 (Not Found)

我无法弄清楚如何解决这个问题。有什么建议吗？

文件夹结构

app/assets/customlibary/css/*
app/assets/customlibary/css/style.css
app/assets/customlibary/js/*
app/assets/customlibary/fonts/*.(svg|eot|woff|tff|)
app/assets/customlibary/images/*
app/assets/customlibary/images/hero-image.jpg

app/assets/stylesheets/themes/theme.css'
app/assets/stylesheets/style1.css'
app/assets/stylesheets/style2.css'

在config.assets.paths中添加路径并不意味着它可以从应用程序的Web根目录中获取资源。 （这是my_app/public）

它为Sprockets和资产助手使用的查找路径添加了一个目录。从样式表链接到资源时，您可以将扩展名更改为.css.erb并使用插值：

.class { background-image: url(<%= image_path 'image.png' %>) }

如果您使用的是SASS，sass-rails会将Rails资产助手映射到SASS功能，以便您可以使用：

.class { background-image: image-url("image.png") }

这不需要您重命名文件。
