Rails 资产管道:自定义字体未加载(已编译 CSS 中的哈希未附加到文件名)

Rails asset pipeline: custom font does not load (hash not appended to file name in compiled CSS)

我有以下 SASS 代码来加载自定义字体:

@font-face
  font-family: 'Fredericka the Great'
  font-style: normal
  font-weight: 400
  src: local('Fredericka the Great'), local('FrederickatheGreat'), asset-url('assets/fredericka_the_great.woff2') format('woff2')
  unicode-range: U+0000-00FF, U+0131, U+0152-0153, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2212, U+2215

在开发中,加载正常。

在我的一台服务器上,它没有。仔细查看生成的代码,我注意到在编译后的 CSS 中,应该加载 woff 文件的位置没有附加哈希值:

@font-face{
  font-family:"Fredericka the Great";
  font-style:normal;
  font-weight:400;
  src:local("Fredericka the Great"),local("FrederickatheGreat"),url(/assets/fredericka_the_great.woff2) format("woff2");
  unicode-range:U+0000-00FF,U+0131,U+0152-0153,U+02C6,U+02DA,U+02DC,U+2000-206F,U+2074,U+20AC,U+2212,U+2215}

如您所见,编译后的代码生成 url(/assets/fredericka_the_great.woff2),而在服务器上,部署的资产如下所示:

所以在我看来,CSS 应该产生 url(/assets/fredericka_the_great-49badd2a1e856a1d9e3a6cb6189f0426bda9f2b292376395758419c2d0c631b6.woff2)。事实上,尝试手动加载文件是可行的:

但有趣的是,在其他一些服务器上,同一个应用程序按预期工作(这看起来很奇怪,因为 CSS 也缺少哈希)!

(要进一步 CSS 检查,请转至 https://audit.uber.space/assets/application-9e5ba30be64b818da5468c9b39dc20aafa0ce523315d3e6684b96d11e336f603.css - or, funnily enough, just https://audit.uber.space/assets/application.css

让我非常怀疑的是,当我将服务器上的 woff 文件重命名为完全不同的名称时,网站仍在加载该文件。所以可能服务器甚至不发送编译的 woff 文件,而是一些完全不同的 woff 文件(可能直接来自 gem 目录或其他东西)...?

我不确定现在如何继续,因为我不知道预期的行为是什么,也不知道如何修复我的部署。

为了完整起见,这是我的部署配置(我使用 mina):

$ mina -d

我 运行 几个月前也遇到过同样的问题,你有很多事情要做。我是这样解决的:

1.- 路线,先到先得。 最好的方法是保存到 app -> assets -> fonts (You create this folder)。然后,我建议以可读的方式在其中添加您的字体文件 (.woff)。

2.- SASS 我特别需要将此代码添加到我的 application.scsscustom.scss

@font-face {
    font-family: 'Theola Kids Regular';
    font-style: normal;
    font-weight: normal;
    src:font-url('theola-kids.woff');
    src:font-url('theola-kids.woff') format('woff');
} 

注意到 src:font-url,它告诉 rails 查找特定的字体文件。我有两个,一个是路由,一个是路由格式文件。

3.- 管道

一定要在application.rb文件中添加"fonts" 示例:config.assets.paths << Rails.root.join("app", "assets", "fonts") 完成后重新启动您的 rails 服务器并检查它。它必须与此解决方案一起使用。
