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';

只需要把你的字体放在app/assets/fonts文件夹中，并在app开始使用application.rb中编写代码时设置自动加载路径

config.assets.paths << Rails.root。加入("app"， "assets"， "fonts") 而且

然后在css中使用以下代码。

@font面{

 font-family: 'icomoon';
 src: asset-url('icomoon.eot');
 src: asset-url('icomoon.eot') format('embedded-opentype'),
      asset-url('icomoon.woff') format('woff'),
      asset-url('icomoon.ttf') format('truetype'),
      asset-url('icomoon.svg') format('svg');
 font-weight: normal;
 font-style: normal;

}

试一试。

谢谢

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。

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
}

在我的情况下，最初的问题是使用资产url没有结果，而不是简单的url css属性。使用asset-url最终为我在Heroku工作。另外，在/assets/fonts文件夹中设置字体并调用asset-url('font.eot')，而无需添加任何子文件夹或任何其他配置。

我最近将Rails 3应用程序升级到Rails 4时也遇到了类似的问题。我的字体在Rails 4+中不能正常工作，我们只允许将字体保存在app/assets/fonts目录下。但是我的Rails 3应用程序有一个不同的字体组织。所以我必须配置应用程序，使它仍然与Rails 4+有我的字体在不同的地方，而不是app/assets/fonts。我已经尝试了几个解决方案，但在我发现非愚蠢的消化资产宝石后，它只是让它变得如此简单。

通过在Gemfile中添加以下代码行来添加这个gem:

gem 'non-stupid-digest-assets'

然后运行:

bundle install

最后在config/initializers/non_digest_assets中添加以下一行。rb文件:

NonStupidDigestAssets.whitelist = [ /\.(?:svg|eot|woff|ttf)$/ ]

就是这样。这很好地解决了我的问题。希望这对遇到类似问题的人有所帮助。
