Rails 4 - 生产图像和字体未指向指纹

Question

我将自定义主题导入我的 Rails 应用程序主页。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 无法在 app/assets/customlibrary/* 中找到指纹资产 app/assets/customlibrary/css/style.css.

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

我不知道如何解决这个问题。有什么建议吗？

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

它将一个目录添加到 Sprockets 和资产助手使用的查找路径中。从样式表链接到资产时，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' %>) }

如果您正在使用 SASS，sass-rails 将 Rails 资产助手映射到 SASS 函数，因此您可以只使用：

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

这不需要您重命名文件。
