Tip

For Font Awesome 5 or 6 support, please consider font-awesome-sass.

---

font-awesome-rails

font-awesome-rails provides the Font-Awesome web fonts and stylesheets as a Rails engine for use with the asset pipeline.

Installation

Add this to your Gemfile:

gem "font-awesome-rails"

and run bundle install.

Usage

In your application.css, include the css file:

/*
 *= require font-awesome
 */

Then restart your webserver if it was previously running.

Congrats! You now have scalable vector icon support. Pick an icon and check out the FontAwesome Examples.

Sass Support

If you prefer SCSS, add this to your application.css.scss file:

@import "font-awesome";

If you use the Sass indented syntax, add this to your application.css.sass file:

@import font-awesome

Helpers

There are also some helpers (fa_icon and fa_stacked_icon) that make your views icontastic!

fa_icon "camera-retro"
# => <i class="fa fa-camera-retro"></i>

fa_icon "camera-retro", text: "Take a photo"
# => <i class="fa fa-camera-retro"></i> Take a photo

fa_icon "chevron-right", text: "Get started", right: true
# => Get started <i class="fa fa-chevron-right"></i>

fa_icon "quote-left 4x", class: "text-muted pull-left"
# => <i class="fa fa-quote-left fa-4x text-muted pull-left"></i>

content_tag(:li, fa_icon("check li", text: "Bulleted list item"))

Misc

Rails engines

When building a Rails engine that includes font-awesome-rails as a dependency, be sure to require "font-awesome-rails" somewhere during the initialization of your engine. Otherwise, Rails will not automatically pick up the load path of the font-awesome-rails assets and helpers (source 1, source 2, source 3).

Deploying to sub-folders

It is sometimes the case that deploying a Rails application to a production environment requires the application to be hosted at a sub-folder on the server. This may be the case, for example, if Apache HTTPD or Nginx is being used as a front-end proxy server, with Rails handling only requests that come in to a sub-folder such as http://example.com/myrailsapp. In this case, the FontAwesome gem (and other asset-serving engines) needs to know the sub-folder, otherwise you can experience a problem roughly described as "my app works fine in development, but fails when I deploy it".

To fix this, set the relative URL root for the application. In the environment file for the deployed version of the app, for example config/environments/production.rb, set the config option action_controller.relative_url_root:

MyApp::Application.configure do
  ...

  # set the relative root, because we're deploying to /myrailsapp
  config.action_controller.relative_url_root  = "/myrailsapp"

  ...
end

The default value of this variable is taken from ENV['RAILS_RELATIVE_URL_ROOT'], so configuring the environment to define RAILS_RELATIVE_URL_ROOT is an alternative strategy.

In addition you need to indicate the subfolder when you precompile the assets:

RAILS_ENV=production bundle exec rake assets:precompile RAILS_RELATIVE_URL_ROOT=/myrailsapp

Rails 3.2

Note

In Rails 3.2, make sure font-awesome-rails is outside the bundler asset group so that these helpers are automatically loaded in production environments.
