title: Uploading/Downloading files - Ruby On Rails system
body: <p>I'm attempting to create a simple file hosting system using Ruby On Rails - I have a large ammount of the system setup (including the registration of new files, and stuff) however I've realised there is a bit of a problem - I'm unsure how to actually get it so that users can upload and download files.
  I assume I'd need some kind of file_link attribute for my file object, but how would people upload and download files to/from the server?</p>
  
  <p>Also (this may be a slightly different topic) - but how would I get the file information such as file size and name (as I need them for the upload)?</p>
  
  <p>Sorry for all my questions - I've don't really deal with file handling a lot so am new to the area.</p>
  
  <p>Thanks In Advance,</p>
  
  <p>Regards,</p>
  
  <p>Joe</p>
