title: Roo Error need to Convert a Mail::Part to a file
body: <p>I access an email attachment from an email (gmail) in ruby using <code>messages.attachments</code></p>
  
  <p>To access the first attachment I do <code>attachment = messages.attachment[0]</code></p>
  
  <p>This attachment is always going to be an .xslx file and when using the roo gem (parses excel) to access it and parse it I keep getting the error "can't convert Mail::Part into String"</p>
  
  <p>What is Mail::Part and how can I convert this to a file or a path to a file Roo would understand </p>
