重命名回形针上传的文件

Question

How do I rename files uploaded by Paperclip? I have uploaded file /public/system/attachments/15/original/abc.txt

How do I rename abc.txt file into for example xyz.txt ? I know how to update file name attributes of an object, but how to make these changes on the file system?

Answer 1

You need to adapt the:url and :path options from has_attached_file

In this great tutorial (thewebfellas.com) you'll find it all. :)

edit: to just move on disk, after having completed the uploading, you can use FileUtils

#!/usr/bin/env ruby

require 'fileutils'

FileUtils.mv('/your/old/file', '/your/new/file')

Oh and File::rename as well of course.

#!/usr/bin/env ruby
File.rename("afile", "afile.bak")
