关于django：Freezegun总是导致RuntimeWarning接收天真的日期时间

Freezegun always causes RuntimeWarning of receiving naive datetime

我正在处理一个可以挂起组织的测试用例。目前我用freezegun来冻结一个固定时间，这是datetime.datetime对象和tzinfo=pytz.UTC对象。

在下面的测试中，您将看到一个返回tzaware日期时间的self.fake_datetime的打印件：2000-01-01 00:00:00+00:00。

当测试运行时，我不断得到著名的RuntimeWarning：

/usr/local/lib/python2.7/dist-packages/django/db/models/fields/init.py:1447: RuntimeWarning: DateTimeField Organization.suspended received a naive datetime (2000-01-01 00:00:00) while time zone support is active.
RuntimeWarning)

from freezegun import freeze_time

class OrganizationSuspendTestCase(TestCase):

def setUp(self):
self.organization = OrganizationFactory()
self.fake_datetime = datetime.datetime(2000, 1, 1, 0, 0, 0, tzinfo=pytz.UTC)
print self.fake_datetime

def test_suspend_organization(self):
"""
Case: An organization is being suspended with the suspend service.
Expected: The organization is updated with the suspending datetime and the reason.
"""
with freeze_time(self.fake_datetime):
mc_organization.services.organization.suspend(organization=self.organization, reason="Did not pay the bill")

self.assertEqual(self.organization.suspended, datetime.datetime(2000, 1, 1, 0, 0, 0))

我一直在玩Freezegun时区示例，但没有成功删除运行时警告。

关于如何正确解决这个问题有什么建议吗？我想继续使用freezegun，不用RuntimeWarning。压制是一种选择，但我不喜欢。

更新——基于Xyres答案的解决方案

服务未意识到正在保存日期时间时区。旧情况注释，新情况是实际代码。我想了很多关于mocking的事情，并假设service中保存的日期时间将被freezegun从测试用例中模拟出的时区感知的日期时间对象，而事实并非如此。
