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

原文 2010-07-24 01:39:59 2 1 ruby-on-rails/ file

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.
