title: How do I save a NamedTemporaryFile into a model FileField in Django?
body: <p>I created a NamedTemporaryFile, added some content in it and now I want to save it into a model FileField. </p>
  
  <p>The problem is that I get a SuspiciousOperation because the tmp directory is not within the FileSystemStorage directory.</p>
  
  <p>What's the proper way to do this?</p>
