Question

我尝试实现Django Oauth，以便使用基于类的方法生成用户创建的Access令牌。

serializer.py

class UserCreateSerializer(ModelSerializer):            

    def create(self, validated_data):
        user = User.objects.create_user(validated_data['username'], 
            validated_data['email'],
            validated_data['password'])
        return user

    class Meta:
        model = User
        fields = ('username', 'email' ,'password')

views.py

class User_Create_view(CreateAPIView):
    serializer_class = UserCreateSerializer
    queryset = User.objects.all()
    permission_classes = [AllowAny]
    authentication_classes = Has_Access_Token

    def create(self, request):
        serializers =self.serializer_class(data=request.data)
        if serializers.is_valid():
            # pdb.set_trace()
            serializers.save()
            #Has_Access_Token.access_token()
            return Response(serializers.data)

permission.py

class Has_Access_Token(BaseAuthentication):
   def access_token(request):
     app = Application.objects.get(name="testing")
     tok = generate_token()

     acce_token=AccessToken.objects.create(
            user=User.objects.all().last(),
            application=app,
            expires=datetime.datetime.now() + datetime.timedelta(days=365),
            token=tok)
    return acce_token

 # @method_decorator(access_token)
    def authenticate(self):
        return request

如果我使用上面的隐式方法，就创建用户而不是最佳实践生成访问令牌。因此，为了在APIView中创建自定义身份验证类，标准过程是什么，无论是关于装饰器还是通过BaseAuthentication类，我应该更改什么。

当我不使用装饰器时

  File "/home/allwin/Desktop/response/env/local/lib/python2.7/site-packages/rest_framework/views.py", line 262, in get_authenticators
    return [auth() for auth in self.authentication_classes]
    TypeError: 'type' object is not iterable

当我使用装饰器

时

File "/usr/lib/python2.7/functools.py", line 33, in update_wrapper
    setattr(wrapper, attr, getattr(wrapped, attr))
AttributeError: 'tuple' object has no attribute '__module__'

如何调试上述问题，解决装饰器问题还是改变类变量？

Django Oauth问题'AccessToken'对象不可调用或不可迭代
