关于python：Django：RunTimeWarning：DateTimeField在时区支持处于活动状态时收到了一个天真的日期时间

Django : RunTimeWarning : DateTimeField received a naive datetime while time zone support is active

我正在尝试测试基于django cart的购物车创建

但当我尝试创建购物车时出现此错误：

RunTimeWarning : DateTimeField received a naive datetime while time zone support is active

我做了一些研究，但我不能解决我的问题。

cart_from_database = models.Cart.objects.get(pk=id)
self.assertEquals(cart, cart_from_database)

型号.py：

1 2	class Cart(models.Model): creationDate = models.DateTimeField()

我的环境中也有USE_TZ = True。

我试过timezone.now()，但还是不行：

def _create_cart_in_database(self, creationDate=timezone.now(), checkedOutDate=True):

def test_cart_creation(self):
creationDate = timezone.now()

RunTimeWarning : DateTimeField Cart.creationDate received a naive datetime (2016-06-03 08:46:34.829000) while time zone support is active.

编辑：

我现在有这个错误，它似乎是一个错误格式日期时间？
