Getting absolute path to the file inside the public folder in Rails

Question

What is the best way to get absolute path to the file inside the public folder in controller? Is there a predefined Rails variable that holds absolute path to the public folder?

Currently I'm using File.expand_path('../../../public', __FILE__), but I'm sure there's a nicer way of doing this.

Rails.public_path should provide you the public path

Great, thanks! I also found "#{RAILS_ROOT}/public", but your method is way nicer. – Vincent Jul 24 '10 at 02:11
