如何在Django rest框架中更新实例？

Question

I have a question about how I can update an instance in django rest framework.

So basically I want to update my user profile through an request but I cannot get current user Id. Is there a better way to get current user and update its information? This is not working because request.user is always anonymous.

@api_view(['POST'])
def update_profile(request):

    serializer = AccountSerializer(request.user, data=request.data)

    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data, status=status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) 

Thank you so much!

If request.user is always anonymous here, you could:

1. Check to see if request.user.is_authenticated before anything else and redirect unauthenticated users to a login page (or use a @login_required decorator), or

2. Get a user object based on data from a URL parameter/kwarg instead of basing it on the user making the request. For instance, perhaps yourapp/users/1 grabs the 1 from the URL and uses for a primary key lookup.
