Additional context (Add any other context about the problem here)
RuntimeError: You called this URL via PUT, but the URL doesn't end in a slash and you have APPEND_SLASH set. Django can't redirect to the slash URL while maintaining PUT data. Change your form to point to 127.0.0.1:8000/usernotes/9/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings.
