Getting absolute path to the file inside the public folder in Rails
提问by Vincent
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?
获取控制器公用文件夹内文件绝对路径的最佳方法是什么？是否有预定义的 Rails 变量保存公共文件夹的绝对路径？
Currently I'm using File.expand_path('../../../public', __FILE__), but I'm sure there's a nicer way of doing this.
目前我正在使用File.expand_path('../../../public', __FILE__)，但我确信有更好的方法来做到这一点。

Rails.public_path应该为您提供公共路径
