Font asset without digest in Ruby on Rails 4

I've been looking at a similar issue and am currently using the non-stupid-digest-assets gem: https://github.com/alexspeller/non-stupid-digest-assets

For more info on how you can use it, see here. Correct use of non-stupid-digest-assets gem

Now that being said, the link provided by Chris (specifically, https://stackoverflow.com/a/17367264/291640) seems like it may accomplish the same as the gem without the gem itself. I know I need to look into it further.

Make sure you have the exact filename WITH extention name of the font in your font-url declaration like:

Correct:

@font-face{
  font-family: 'Sawasdee';
  src: font-url('Sawasdee.ttf') format('truetype');
}

Wrong:

@font-face{
  font-family: 'Sewasdee';
  src: font-url('Sewasdee') format('truetype');
}

My font folder:

fonts
 |_ Sewasdee.ttf
 |_ Otherfont.ttf

Here is our solution, that is based partially on what Sprocets does. It is working with Rails4. It automatically generates a nondigest version for all assets, that were listed in config.assets.precompile, after precompilation was done.

# lib/tasks/assets_nondigest.rake
require 'fileutils'

namespace "assets:precompile" do
  desc "Create nondigest versions of defined assets"
  task :nondigest => :environment do
    sprocket_task = Sprockets::Rails::Task.new ::Rails.application
    assets = ::Rails.application.config.assets.precompile

    paths = sprocket_task.index.each_logical_path(assets).to_a +
      assets.select { |asset| Pathname.new(asset).absolute? if asset.is_a?(String)}

    paths.each do |path|
      if asset = sprocket_task.index.find_asset(path)
        copy_target = File.join(sprocket_task.output, asset.digest_path)
        target = File.join(sprocket_task.output, asset.logical_path)

        sprocket_task.logger.info "Writing #{target}"
        asset.write_to target
        asset.write_to "#{target}.gz" if asset.is_a?(Sprockets::BundledAsset)
      end
    end
  end
end

Rake::Task['assets:precompile'].enhance do
  Rake::Task['assets:precompile:nondigest'].invoke
end
