title: Can I add permissions to media django media files?
body: <p>I want to build an app and let user to see some videos just if they have permissions or they paid for that video. I am using Django and I want to add ngnix and gunicorn to serve media files.
  I am not sure if once the user has the url of the video, how can I block him to not see the video if his payment expired or he doesn't have the permissions. For now I let django to serve the videos and I overwrite the server method and if he doesn't have access to video I return 404.</p>
