ruby not load font-awesome

i am trying to load font-awesome to my view

I have read other answers and implement the Rails: Using Font Awesome

What i have done

config/application.rb

require File.expand_path('../boot', __FILE__)

require 'rails/all'


    # Require the gems listed in Gemfile, including any gems
    # you've limited to :test, :development, or :production.
    Bundler.require(:default, Rails.env)

    module Blog
      class Application < Rails::Application
        # Settings in config/environments/* take precedence over those specified here.
        # Application configuration should go into files in config/initializers
        # -- all .rb files in that directory are automatically loaded.

        # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
        # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
        # config.time_zone = 'Central Time (US & Canada)'

        # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
        # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
        # config.i18n.default_locale = :de

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

I have rename the font-awesome.min.css to font-awesome.min.css.erb and use assets_path

@font-face{font-family:'FontAwesome';
 src:url('<%= asset_path("fontawesome-webfont.eot?v=4.0.3") %>');
 src:url('<%= asset_path("awesome-webfont.eot?#iefix&v=4.0.3") %>') format('embedded-opentype'),
 url('<%= asset_path("fontawesome-webfont.woff?v=4.0.3") %>') format('woff'),
 url('<%= asset_path("fontawesome-webfont.ttf?v=4.0.3") %>') format('truetype'),
 url('<%= asset_path("fontawesome-webfont.svg?v=4.0.3#fontawesomeregula") %>') format('svg');
 font-weight:normal;font-style:normal}

and load the css file on the view

<%= stylesheet_link_tag 'bootstrap.css' %>
  <%= stylesheet_link_tag 'animate.css' %>
  <%= stylesheet_link_tag 'font-awesome.min.css' %>
  <%= stylesheet_link_tag 'font.css' %>
  <%= stylesheet_link_tag 'app.css' %>

and on Chrome the font files are not loaded

and on server i get

Started GET "/fontawesome-webfont.ttf?v=4.0.3" for 127.0.0.1 at 2014-02-14 08:36:37 +0200

Please help

The easiest way to integrate font-awesome to rails is via font-awesome-rails gem. It will integrate font-awesome to rails asset pipeline.

In your Gemfile add

gem "font-awesome-rails"

and run bundle install to install the gem

Then in your scss file import it using

@import "font-awesome";

That's it! Now you can use it in your view as

<i class="fa fa-bell-o"></i>

If you prefer to use css instead of scss then add the require statement in your application.css

*= require font-awesome

Update

If you don't want to use font-awesome-rails gem then follow the steps

Place your fonts in the folder app/assets/fonts

In config/application.rb add the following lines

# Add fonts path
config.assets.paths << "#{Rails.root}/app/assets/fonts"

# Precompile additional assets
config.assets.precompile += %w( .svg .eot .woff .ttf )

Declare your font in font-awesome.css.erb like

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

I hope this will help you.
