fontawesome + rails 4.0.1无法正常工作

Question

我在我的rails 4.0.1项目中使用了fontawesome 3.2.1和bootstrap 3.0.0.我的所有资产都位于供应商/资产中.

问题是我的fontawesome正在开发模式,当我编译我的资产(生产环境)并在生产环境中运行服务器,它无法加载fontawesome.错误是

Started GET "/assets/fontawesome-webfont.svg" for 127.0.0.1 at 2014-01-08 11:48:55 +0530

ActionController::RoutingError (No route matches [GET] "/assets/fontawesome-webfont.svg"):
 actionpack (4.0.1) lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call'
 actionpack (4.0.1) lib/action_dispatch/middleware/show_exceptions.rb:30:in `call'

资产是

$ls vendor/assets/
=> fonts  images  javascripts  stylesheets

$ls vendor/assets/*
=> vendor/assets/fonts:
FontAwesome.otf          fontawesome-webfont.ttf           glyphicons-halflings-   regular.svg
fontawesome-webfont.eot  fontawesome-webfont.woff          glyphicons-halflings- regular.ttf
fontawesome-webfont.svg  glyphicons-halflings-regular.eot  glyphicons-halflings-regular.woff

vendor/assets/images:
bg_direction_nav.png  bxslider  search-icon.jpg

vendor/assets/javascripts:
bootstrap  bxslider  fancybox  others  revolution_slider

vendor/assets/stylesheets:
bootstrap  bxslider  fancybox  font_awesome  others  revolution_slider

 $ls vendor/assets/stylesheets/bootstrap/
 => bootstrap.min.css

 $ls vendor/assets/stylesheets/font_awesome/
 => font-awesome.css

我的application.css是

$cat app/assets/stylesheets/application.css 
/*
* This is a manifest file that'll be compiled into application.css, which will include   all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
*

* compiled file, but it's generally better to create a new file per style scope.

*= require revolution_slider/rs-style.css
*= require revolution_slider/settings.css
*= require others/flexslider.css 
*= require others/style.css
*= require others/style-responsive.css
*= require_self
*/

fontawesome被加载到font-awesome.css中

@font-face {
  font-family: 'FontAwesome';
  src: url('/assets/fontawesome-webfont.eot?v=3.2.1');
  src: url('/assets/fontawesome-webfont.eot?#iefix&v=3.2.1') format('embedded-opentype'), url('/assets/fontawesome-webfont.woff?v=3.2.1') format('woff'), url('/assets/fontawesome-webfont.ttf?v=3.2.1') format('truetype'), url('/assets/fontawesome-webfont.svg#fontawesomeregular?v=3.2.1') format('svg');
  font-weight: normal;
  font-style: normal;
}

glyphicons在bootstrap.min.css中加载为

@font-face{
  font-family:'Glyphicons Halflings';
  src:url('/assets/glyphicons-halflings-regular.eot');
  src:url('/assets/glyphicons-halflings-regular.eot?#iefix') format('embedded-Opentype'), url('/assets/glyphicons-halflings-regular.woff') format('woff'),url('/assets/glyphicons-halflings-regular.ttf') format('truetype'),url('/assets/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg')}

我确实尝试了几个解决方案,例如将'font'或'assets'添加到'url'但没有工作.

--update

config/application.rb的内容

config.assets.enabled = true
config.assets.version = '1.0'

config.assets.paths += ["#{config.root}/vendor/assets/fonts", "#config.root}/app/assets/images/**", "#{config.root}/vendor/assets/images"]
config.assets.precompile += %w(*.png *.jpg *.jpeg *.gif *.eot *.svg *.ttf *.otf *.woff vendor/assets/stylesheets/**/* vendor/assets/fonts/*)

["#{config.root}/vendor/assets/javascripts", "#config.root}/vendor/assets/stylesheets"].each do |d|
config.assets.precompile += Dir.glob("#{d}/*").map{|f| "#{f.gsub(d + '/', '')}/**/*" if File.directory?(f)}.compact

我解决了下面指定的问题.

1)首先,不要在.css文件中引用资产.将文件重命名为.css.scss.每当你创建控制器并且它为该控制器创建资产时,这就是相同的扩展.(javascript和css).有多个应用程序将css转换为scss.如果css很大,请使用它们.

2)每当你想在样式表中引用字体时,都要使用font-path.即.使用rails提供的方法来引用资产而不是使用'src', 例如

@font-face {
  font-family: 'MuseoSans-700';
  src: url(font-path('museoSans/244DD4_0_0.eot'));
  src: url(font-path('museoSans/244DD4_0_0.eot?#iefix')) format('embedded-opentype');
  src: url(font-path('museoSans/244DD4_0_0.woff')) format('woff');
  src: url(font-path('museoSans/244DD4_0_0.ttf')) format('truetype');
}

在上面的代码中,我的文件是"app/assets/stylesheets/fonts.scss",我的字体位于

$ls vendor/assets/fonts/
  fontawesome  museoSans  museoSans500
$ls vendor/assets/fonts/museoSans
  244DD4_0_0.eot   244DD4_1_0.ttf   244DD4_2_0.woff  244DD4_4_0.eot   244DD4_5_0.ttf   244DD4_6_0.woff  244DD4_8_0.eot   244DD4_9_0.ttf
  244DD4_0_0.ttf   244DD4_1_0.woff  244DD4_3_0.eot   244DD4_4_0.ttf   244DD4_5_0.woff  244DD4_7_0.eot   244DD4_8_0.ttf   244DD4_9_0.woff
  244DD4_0_0.woff  244DD4_2_0.eot   244DD4_3_0.ttf   244DD4_4_0.woff  244DD4_6_0.eot   244DD4_7_0.ttf   244DD4_8_0.woff
  244DD4_1_0.eot   244DD4_2_0.ttf   244DD4_3_0.woff  244DD4_5_0.eot   244DD4_6_0.ttf   244DD4_7_0.woff  244DD4_9_0.eot

3)在资产预编译期间,像'font-path'或'asset-path'这样的帮助程序有助于指向正确的资产.即.如果你指定它

src: url('/assets/museoSans/244DD4_0_0.eot'));

在编译的资产中,这仍然是相同的.它理想情况下应该是

src: url('/assets/museoSans/244DD4_0_0-67652745236457645234dghfhsagfd64354.eot'));

您可以'grep'并查看"public/assets"中的编译文件.

4)确保资产加载的另一种方法是从url调用它们.

5)请在生产或登台env文件中设置'config.assets.compress = false'并在prod/staging env中本地运行应用程序,以便检查视图以确保资源正在加载.

Answer 2

您的svg似乎没有编译,指纹似乎丢失,除非您设置:

config.assets.digest = false 

预编译后我得到了相同的"没有路由匹配GET".你可以尝试在config/application.rb中添加svg:

config.assets.precompile += %w(*.svg)

然后重试一次:

rake assets:precompile RAILS_ENV=production

在我的例子中,一个简单的rake资产:预编译是不够的我需要指定RAILS_ENV和RAILS_GROUPS(如果rails的版本低于4).

通常,编译的资产位于public/assets目录中.

我希望它有所帮助

更新:

另一个想法来自于我在生产中使用带有导轨4的ckeditor的经验.使用摘要的资产编译无效(https://github.com/galetahub/ckeditor).您需要添加一个rake任务,在编译后复制/修改public/assets目录中的某些文件.这是代码:

namespace :ckeditor do
  desc 'Create nondigest versions of some ckeditor assets (e.g. moono skin png)'
  task :create_nondigest_assets do
    fingerprint = /\-[0-9a-f]{32}\./
    for file in Dir['public/assets/ckeditor/contents-*.css', 'public/assets/ckeditor/skins/moono/*.png']
      next unless file =~ fingerprint
      nondigest = file.sub fingerprint, '.' # contents-0d8ffa186a00f5063461bc0ba0d96087.css => contents.css
      FileUtils.cp file, nondigest, verbose: true
    end
  end
end

# auto run ckeditor:create_nondigest_assets after assets:precompile
Rake::Task['assets:precompile'].enhance do
  Rake::Task['ckeditor:create_nondigest_assets'].invoke
end

您可以使用fontawsome轻松替换ckeditor.
