JWT authentication middleware for django rest framework that populates the request.user object

jwt_authentication.py

from django.utils.functional import SimpleLazyObject
from django.contrib.auth.models import AnonymousUser

from rest_framework.request import Request
from rest_framework_jwt.authentication import JSONWebTokenAuthentication


def get_user_jwt(request):
    """
    Replacement for django session auth get_user & auth.get_user for
     JSON Web Token authentication. Inspects the token for the user_id,
     attempts to get that user from the DB & assigns the user on the
     request object. Otherwise it defaults to AnonymousUser.

    This will work with existing decorators like LoginRequired, whereas
    the standard restframework_jwt auth only works at the view level
    forcing all authenticated users to appear as AnonymousUser ;)

    Returns: instance of user object or AnonymousUser object
    """
    user = None
    try:
        user_jwt = JSONWebTokenAuthentication().authenticate(Request(request))
        if user_jwt is not None:
            # store the first part from the tuple (user, obj)
            user = user_jwt[0]
    except:
        pass

    return user or AnonymousUser()


class JWTAuthenticationMiddleware(object):
    """ Middleware for authenticating JSON Web Tokens in Authorize Header """
    def process_request(self, request):
        request.user = SimpleLazyObject(lambda : get_user_jwt(request))

Sorry, I am new to Django, but once I put this inplace, I am no longer able to access the admin page. It throws "'AnonymousUser' object is not callable". Can you suggest a way to solve this? Thanks

Yeah this is dated, follow @diegojancic advice for newer versions. This was last used on probably django 1.9 maybe? Its been a while - I've been living in universal javascript for a while now. Thanks!
