I found a way to do that, it involves declaring a MiddleWare, though. Create a file called get_username.py inside your app, with this content:

from threading import current_thread

_requests = {}

def get_username():
    t = current_thread()
    if t not in _requests:
         return None
    return _requests[t]

class RequestMiddleware(object):
    def process_request(self, request):
        _requests[current_thread()] = request

Edit your settings.py and add it to the MIDDLEWARE_CLASSES:

MIDDLEWARE_CLASSES = (
    ...
    'yourapp.get_username.RequestMiddleware',
)

Now, in your save() method, you can get the current username like this:

from get_username import get_username

...

def save(self, *args, **kwargs):
    req = get_username()
    print "Your username is: %s" % (req.user)
