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

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 usin开发者_StackOverflow社区g 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
