我有一些字体被配置在我的Scss文件如下:

@font-face {
  font-family: 'Icomoon';
  src: asset-url('icoMoon.eot?#iefix', font) format('embedded-opentype'),
       asset-url('icoMoon.woff', font) format('woff'),
       asset-url('icoMoon.ttf', font)  format('truetype'),
       asset-url('icoMoon.svg#Icomoon', font) format('svg');
}

实际的字体文件存储在/app/assets/fonts/中

我添加了config.assets.paths << Rails.root。加入(“应用程序”,“资产”,“字体”)到我的应用程序。rb文件

编译CSS源代码如下:

@font-face {
  font-family: 'Icomoon';
  src: url(/assets/icoMoon.eot?#iefix) format("embedded-opentype"), url(/assets/icoMoon.woff) format("woff"), url(/assets/icoMoon.ttf) format("truetype"), url(/assets/icoMoon.svg#Icomoon) format("svg");
}

但当我运行应用程序的字体文件没有被发现。日志:

start GET "/assets/icoMoon.ttf" for 127.0.0.1 at 2012-06-05 23:21:17 +0100 已服务资产/icoMoon.ttf - 404 Not Found (13ms)

为什么资产管道不把字体文件压缩成/assets?

大家有什么想法吗?

亲切的问候, 尼尔。

额外信息:

当检查rails控制台的资产路径和assetprecompile时,我得到如下:

当前回答

这里有一个转折:

你应该把所有的字体放在app/assets/fonts/中,因为它们在默认情况下会在登台和生产中被预编译——当推送到heroku时,它们会被预编译。 默认情况下,放置在vendor/assets中的字体文件不会在登台或生产时预编译-它们将在heroku上失败。源!

我坚信把厂商字体放到厂商/资产/字体中 这比把它们放到app/assets/字体中更有意义。与 这两行额外的配置对我来说工作得很好 Rails 4):

app.config.assets.paths << Rails.root.join('vendor', 'assets', 'fonts')  
app.config.assets.precompile << /\.(?:svg|eot|woff|ttf)$/

我还在rails 4.0.0上测试了它。实际上,最后一行已经足够从供应商文件夹安全预编译字体了。花了几个小时才弄明白。希望它能帮助到某人。

其他回答

If your Rails version is between > 3.1.0 and < 4, place your fonts in any of the these folders: app/assets/fonts lib/assets/fonts vendor/assets/fonts For Rails versions > 4, you must place your fonts in the app/assets/fonts folder. Note: To place fonts outside of these designated folders, use the following configuration: config.assets.precompile << /\.(?:svg|eot|woff|ttf)\z/ For Rails versions > 4.2, it is recommended to add this configuration to config/initializers/assets.rb. However, you can also add it to either config/application.rb , or to config/production.rb Declare your font in your CSS file: @font-face { font-family: 'Icomoon'; src:url('icomoon.eot'); src:url('icomoon.eot?#iefix') format('embedded-opentype'), url('icomoon.svg#icomoon') format('svg'), url('icomoon.woff') format('woff'), url('icomoon.ttf') format('truetype'); font-weight: normal; font-style: normal; } Make sure your font is named exactly the same as in the URL portion of the declaration. Capital letters and punctuation marks matter. In this case, the font should have the name icomoon. If you are using Sass or Less with Rails > 3.1.0 (your CSS file has .scss or .less extension), then change the url(...) in the font declaration to font-url(...). Otherwise, your CSS file should have the extension .css.erb, and the font declaration should be url('<%= asset_path(...) %>'). If you are using Rails > 3.2.1, you can use font_path(...) instead of asset_path(...). This helper does exactly the same thing but it's more clear. Finally, use your font in your CSS like you declared it in the font-family part. If it was declared capitalized, you can use it like this: font-family: 'Icomoon';

把你的字体文件(woff, woff2, eot, ttf,…)放在/app/assets/fonts目录下。

然后添加以下到您的配置/初始化/资产。rb:

Rails.application.config.assets.paths << Rails.root.join('app', 'assets', 'fonts')
Rails.application.config.assets.precompile << /\.(?:svg|eot|woff|woff2|ttf)\z/

在上面的答案中,woff2没有包括在内(为了将来的参考,你可能需要添加其他扩展,只需在这里添加|{font-file-extension})

使用css文件中的字体:

重要的是,你需要将它从stylesheet.css重命名为stylesheet.css.scss(这是为了让font-url在资产预编译后正确地在生产中转换字体的url):

@font-face {
  font-family: 'MyFont'
  src: font-url('myfont.woff') format('woff');
}

body{
  font-family: 'MyFont'
}

然后运行:

rails assets:precompile

在运行资产预编译后,你的字体文件从app/assets/fonts/myfont复制。woff到public/assets/myfont-{SOME_DIGEST_KEY}。woff的位置。现在上面的css在生产中也很像图像资产。

您还可以看到,在预编译资产命令之后创建了一个应用程序-{somedigest}.css,在其中您将看到 现在,我们的font-url('myfont.woff')将被转换为url(/assets/myfont.woff-{SOME_DIGEST_KEY}.woff),并且摘要与文件移动到的位置匹配。通过这种方式,更新你的字体文件也可以适当地破坏浏览器缓存等。

确保你的nginx也服务于public/assets文件夹以获得更好的性能。这是用rails 5和rails 6在生产中测试的。它也应该工作与rails 4最有可能。

我使用Rails 4.2,并不能得到footable图标显示。显示的是小方框,而不是我所期望的折叠行上的(+)和小排序箭头。在学习了这里的信息之后,我对代码做了一个简单的更改:删除css中的字体目录。也就是说,像这样更改所有的css条目:

src:url('fonts/footable.eot');

看起来像这样:

src:url('footable.eot');

它工作。我认为Rails 4.2已经假定了字体目录,所以在css代码中再次指定它会使字体文件找不到。希望这能有所帮助。

你需要在@font-face块中使用font-url,而不是url

@font-face {
font-family: 'Inconsolata';
src:font-url('Inconsolata-Regular.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}

以及这条线在应用中。Rb,正如你提到的(对于app/assets/fonts中的字体

config.assets.paths << Rails.root.join("app", "assets", "fonts")

如果你不想跟踪字体的移动:

# Adding Webfonts to the Asset Pipeline
config.assets.precompile << Proc.new { |path|
  if path =~ /\.(eot|svg|ttf|woff)\z/
    true
  end
}
