Rails 7 上的 scss 文件中的 url() 错误
我在使用 Rails 7 项目中的 url() css 函数时遇到问题。我在一个全新的版本上复制了它： https://github.com/paul-mesnilgrente /rails-7-url，请参阅此提交：https://github.com/paul-mesnilgrente/rails-7-url/commit/77e1379cd98827f43b02605852220cd3db93ce06
它使用 sass (参见 package.json) 以及 cssbundling-rails 和 sprockets-rails。如果您查看app/assets/stylesheets/application.sass.scss，我有：background-image: url('images/background.jpg')。 background.jpg 文件是 app/assets/images/background.jpg。
我尝试了几种路径来包含该背景（../images/background.jpg、/images/background.jpg 等），但没有任何效果。开发环境中的编译结果应该附加一个摘要哈希，但没有任何内容，并且路径仅转换为 /images/background.jpg ，这给出了 404。这让我觉得 sprockets 没有找不到背景图像，因此它不会“编译”该路径。
对我做错了什么有什么想法吗？
I'm having troubles with the url() css function in my rails 7 project. I reproduced it on a brand new one: https://github.com/paul-mesnilgrente/rails-7-url, see this commit: https://github.com/paul-mesnilgrente/rails-7-url/commit/77e1379cd98827f43b02605852220cd3db93ce06
It uses sass (see package.json) with cssbundling-rails and sprockets-rails. If you look at the app/assets/stylesheets/application.sass.scss, I have: background-image: url('images/background.jpg'). And the background.jpg file is app/assets/images/background.jpg.
I tried several paths to include that background (../images/background.jpg, /images/background.jpg etc.) but nothing works. The compiled result in the development environment should have a digest hash appended to it but there's nothing and the path is only translated to /images/background.jpg which gives a 404. This makes me thing that sprockets doesn't find the background image so it doesn't "compile" that path.
Any ideas of what I'm doing wrong?

我发现这个问题实际上很愚蠢。在manifest.js中，我们默认有这一行
//= link_tree ../images。问题是，rails 不会查找相对于样式表甚至相对于
app/assets的资源。它仅相对于那些//= link_tree ...路径。所以我之前没有尝试过的正确路径是 url("background.jpg") 。
旁注：如果您使用包含相对路径的数据表等库，则需要在manifest.js中添加一些链接
//= link_tree ../../../node_modules /datatables.net-zf/cssI found the problem which was actually pretty dumb. In manifest.js we have this line by default
//= link_tree ../images.And the thing is, rails doesn't look for the assets relatively to your stylesheet or even relatively to
app/assets. It's only relative to those//= link_tree ...paths.So the right path, which I hadn't tried before was
url("background.jpg").Side note : If you use libraries like datatables which are including relative paths, you need to add something link this in manifest.js
//= link_tree ../../../node_modules/datatables.net-zf/css
