FTPS (TLS/SSL) from Ruby on Rails App

Question

I have an FTP server which only accepts connections through running FTPS (explicit FTP over TLS). I need to be able to connect to this using a Ruby on Rails app.

Answer 1

EDIT: I figured out how to get it running locally, but am having issues getting it to work on Heroku. That's a bit of a departure from this question, so I've created a new one:

Heroku with FTPTLS - Error on SSL Connection

require 'net/ftptls'
ftp = Net::FTPTLS.new()
ftp.passive = true
#make sure you define port_number
ftp.connect('host.com', port_number)
ftp.login('Username', 'Password')
ftp.gettextfile('filename.ext', 'where/to/save/file.ext')
ftp.close
