Rails Material Design Icons

Rails Material Design Icons provides the Material Design Icons web fonts and stylesheets as a Rails engine for use with the asset pipeline.

Most of the work was done in Font Awesome gem, this just changes the files to Material Design Icons. Font Awesome Rails

Add this to your Gemfile:

gem "rails_material_design_icons"

and run bundle install.

In your application.css, include the css file:

/*
 *= require materialdesignicons
 */

Then restart your webserver if it was previously running.

Congrats! You now have scalable vector icon support. Pick an icon and check out the official website for the icons available. https://materialdesignicons.com/.

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

@import "materialdesignicons";

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

@import materialdesignicons

There are also some helpers (mdi and mdi_spin) that make your views icontastic!

mdi "sheep"
# => <i class="mdi mdi-sheep"></i>

mdi_spin # spinning icons!
# => <i class="mdi mdi-sheep mdi-spin"></i>

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
