title: Best way to send mail with attachments uploaded by form in Ruby on Rails
body: <p>what's the best way to upload an attachment by form and send an email? The attachment doesn't need to be stored on the server.</p>
  
  <p>I found a sexy jQuery uploader: <a href="https://github.com/blueimp/jQuery-File-Upload/" rel="nofollow noreferrer">https://github.com/blueimp/jQuery-File-Upload/</a> and a guide for RoR3 <a href="https://github.com/blueimp/jQuery-File-Upload/wiki/jQuery-File-Upload-for-Rails-3" rel="nofollow noreferrer">https://github.com/blueimp/jQuery-File-Upload/wiki/jQuery-File-Upload-for-Rails-3</a></p>
  
  <p>but how to implement without saving as file on the server?</p>
  
  <p>Or is there an other easy way?</p>
  
  <p>Thanks andi</p>
