title: 403 error for new files posted through django admin
body: <p>I'm running a Django server with Gunicorn and Nginx hosted on DigitalOcean. I've run into a problem where adding a new file through the administrator interface produces a 403 forbidden error. Specifically, the file in question works fine if I summon a query of it (e.g. <code>Object.objects.all()</code>)but can't be rendered in my templates. I've previously fixed the problem by doing <code>chmod/chown</code>, but the fix only applies to existing files, not new ones. Does anyone know how to permanently apply the fix once?</p>
