I created login authentication in Rest Api

Question

I created login authentication in Rest Api it Retrieves token key in postman. Right now I need the username of the person associated with a token key.

how to do that ?

# views.py
class LoginView(APIView):

    def post(self, request):

        serializer = LoginSerializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = serializer.validated_data["user"]
        django_login(request, user)
        token, created = Token.objects.get_or_create(user=user)
        return Response({"token": token.key }, status=200)


# serializers.py
class LoginSerializer(serializers.Serializer):
        username = serializers.CharField()
        password = serializers.CharField()

        def validate(self, data):
            username = data.get("username", "")
            password = data.get("password", "")

            if username and password:
                user = authenticate(username=username, password=password)
                if user:
                    if user.is_active:
                        data["user"] = user
                    else:
                        msg = "User is deactivated."
                        raise exceptions.ValidationError(msg)
                else:
                    msg = "Unable to login with given credentials."
                    raise exceptions.ValidationError(msg)
            else:
                msg = "Must provide username and password both."
                raise exceptions.ValidationError(msg)
            return data

After the login authentication the method(Authentication method) will return the user, so you can fetch the user data like this,

username = user.username

Example:

class LoginView(APIView):

def post(self, request):

    serializer = LoginSerializer(data=request.data)
    serializer.is_valid(raise_exception=True)
    user = serializer.validated_data["user"]
    django_login(request, user)
    token, created = Token.objects.get_or_create(user=user)
    return Response({"token": token.key , "username":user.username},status=200)
