Example
If a curl would be run against this endpoint
curl http://localhost:8000/auth/
op : {"detail": "Authentication credentials were not provided."}%
would return a 401 error UNAUTHORIZED
but in case we get a token before:
curl -X POST -d "user=Pepe&password=aaaa" http://localhost:8000/
{"token": "f7d6d027025c828b65cee5d38240aec60dffa150", "detail": "POST answer"}%
and then we put that token into the header of the request like this:
curl http://localhost:8000/auth/ -H 'Authorization: Token f7d6d027025c828b65cee5d38240aec60dffa150'
op: {"detail": "I suppose you are authenticated"}%
