I'm using the Font-Awesome-Sass gem with my Rails Project.

I followed the gem's instructions, and have included the @import into the application.css.scss. I'm also using the correct Rails syntax in the html to reference the icons. Everything works great locally, but as soon as I push to my staging Heroku environment, the icons just show as black squares.

Here is a snippet of staging.rb (the staging Heroku environment I was talking about)

 # Code is not reloaded between requests.
  config.cache_classes = true

  config.eager_load = true

  # Full error reports are disabled and caching is turned on.
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Enable Rack::Cache to put a simple HTTP cache in front of your application
  # Add `rack-cache` to your Gemfile before enabling this.
  # For large-scale production use, consider using a caching reverse proxy like nginx, varnish or squid.
  # config.action_dispatch.rack_cache = true

  # Disable Rails's static asset server (Apache or nginx will already do this).
  config.serve_static_assets = true

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier
  # config.assets.css_compressor = :sass

  # Do not fallback to assets pipeline if a precompiled asset is missed.
  config.assets.compile = true

  # Generate digests for assets URLs.
  config.assets.digest = true

  # Version of your assets, change this if you want to expire all your assets.
  config.assets.version = '1.0'

  # Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
  # config.force_ssl = true

  # Set to :debug to see everything in the log.
  config.log_level = :info

  # Use a different cache store in production.
  # config.cache_store = :mem_cache_store

  # Enable serving of images, stylesheets, and JavaScripts from an asset server.
    config.action_controller.asset_host = "//MYCLOUDFRONTHOSTINGURL-hidden-for-this-question"

  # Enable locale fallbacks for I18n (makes lookups for any locale fall back to
  # the I18n.default_locale when a translation can not be found).
  config.i18n.fallbacks = true

  # Send deprecation notices to registered listeners.
  config.active_support.deprecation = :notify

  # Disable automatic flushing of the log to improve performance.
  # config.autoflush_log = false

  # Use default logging formatter so that PID and timestamp are not suppressed.
  config.log_formatter = ::Logger::Formatter.new

Is there something I'm missing?

Thanks for the help!

This happens when you have another font overriding your icon font. Search your CSS to see if there is another font-family:OtherFont!important;.

First make sure that your Font-awesome CSS is loaded, and font-urls point to the correct fonts.

Then explicitly specify your i.fa tags (which are used by Font-awesome to create the font) to 

i.fa { 
    font-family:FontAwesome!important; 
}

Worked great for me.

I had the same problem! Font awesome was working on local however when deployed to Heroku all icons appeared as a small white square. It was previously working without problem.

This worked for me: Add below line to layout file. 

<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.1.0/css/font-awesome.min.css" rel="stylesheet">

Works fine now.
