Somtimes you need to diff the output of rake assets:precompile run this script after to remove fingerprints

asset.rake

task non_digested: :environment do
  assets = Dir.glob(File.join(Rails.root, 'public/assets/**/*'))
  regex = /(-{1}[a-z0-9]{32}*\.{1}){1}/
  assets.each do |file|
    next if File.directory?(file) || file !~ regex

    source = file.split('/')
    source.push(source.pop.gsub(regex, '.'))

    non_digested = File.join(source)
    FileUtils.mv(file, non_digested)
  end
end
