I found this link, and think may be it helpful for you, please see

keithgaputis's answer. Rails config.assets.precompile setting to process all CSS and JS files in app/assets

I think you can do like following.

# In production.rb
config.assets.precompile << Proc.new { |path|
  if path =~ /\.(css|js)\z/
    full_path = Rails.application.assets.resolve(path).to_path
    app_assets_path = Rails.root.join('app', 'assets').to_path
    if full_path.starts_with? app_assets_path
      puts "excluding asset: " + full_path
      false
    else
      puts "including asset: " + full_path
      true
    end
  else
    false
  end
}
