fontawesome + rails 4.0.1 not working

Question

I am using fontawesome 3.2.1 and bootstrap 3.0.0 in my rails 4.0.1 project. All my assets are located in vendor/assets.

the problem is that my fontawesome is working in development mode when when i compile my assets(production env) and run the server in production env, its not able to load fontawesome. the errors are as

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'

the assets are as

$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

vendor/assets/images:

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

my application.css is as

$cat app/assets/stylesheets/application.css 
/*

* listed below.

*/

fontawesome are loaded in font-awesome.css as

@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 are loaded in bootstrap.min.css as

@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')}

i did try couple of solution like prepending 'font' or 'assets' to 'url' but none worked.

--UPDATE

contents of config/application.rb

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

Answer 1

I solved the problem as specified below.

1) Firstly, dont refer assets inside .css file. Rename the file to .css.scss. Thats the same extension whenever u create controller and it creates assets for that controller.(javascript and css). There are multiple applications to convert css to scss. Use them if the css is large.

2) use font-path whenever you want to refer a font inside a stylesheet. ie. use methods provided by rails to refer to assets rather than using 'src' eg

@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');
}

In the above code, my file is as "app/assets/stylesheets/fonts.scss" and my fonts are located in

$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) During asset precompilation, the helpers like 'font-path' or 'asset-path' help in pointing to the right asset. ie. if u specify it as

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

this is still going to be the same in the compiled asset. it should ideally be

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

You can 'grep' and check out the compiled file in "public/assets".

4) another way of making sure the assets are loading is the to call them from url.

5) Please set 'config.assets.compress = false' in your production or staging env file and run the application locally in prod/staging env so as the check the views to make sure that the assets are loading.

Answer 2

Your svg doesn't seem to be compiled, the fingerprint seems missing except if you set:

config.assets.digest = false 

I was getting the same " no routes match GET" after precompiling. you can try to add the svg here in your config/application.rb:

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

And then retry a:

rake assets:precompile RAILS_ENV=production

In my case a simple rake assets:precompile wasn't enough i needed to specify the RAILS_ENV and RAILS_GROUPS (If the version of rails is lower than 4).

Normally the compiled assets are found in the public/assets directory.

I hope it helps

UPDATE:

Another idea coming from my experience with ckeditor with rails 4 in production. The assets compilation with digest is not working (https://github.com/galetahub/ckeditor). You need to add a rake task that copies/modify some files in the public/assets directory after compilation. Here is the code:

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

You can easily replace ckeditor with fontawsome.
