在Rails的公用文件夹中获取文件的绝对路径 [英] Getting absolute path to the file inside the public folder in Rails

问题描述

获取控制器公用文件夹中文件的绝对路径的最佳方法是什么?是否有预定义的Rails变量来保存公用文件夹的绝对路径?

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?

当前我正在使用File.expand_path('../../../public', __FILE__)，但是我敢肯定有一种更好的方法可以实现这一点.

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

推荐答案

Rails.public_path应该为您提供公共路径

Rails.public_path should provide you the public path
