What is the best way to get an empty temporary directory in Ruby on Rails?

Question

What is the best way to get a temporary directory with nothing in it using Ruby on Rails? I need the API to be cross-platform compatible. The stdlib tmpdir won\'t work.

Answer 1

require 'tmpdir' # not needed if you are loading Rails
tmp_dir = File.join(Dir::tmpdir, "my_app_#{Time.now.to_i}_#{rand(100)}")
Dir.mkdir(tmp_dir)

Works for me.
