Django DateTimeField收到一个简单的datetime

我的问题是,我似乎无法根据时间戳(即日期和时间戳)过滤数据 小时

我的模型如下所示:

# Create your models here.
class HourlyTick(models.Model):
    id = models.IntegerField(primary_key=True)
    timestamp = models.DateTimeField(blank=True, null=True)
    symbol = models.TextField(blank=True, null=True)
    open = models.IntegerField(blank=True, null=True)
    high = models.IntegerField(blank=True, null=True)
    low = models.IntegerField(blank=True, null=True)
    close = models.IntegerField(blank=True, null=True)
    trades = models.IntegerField(blank=True, null=True)
    volume = models.IntegerField(blank=True, null=True)
    vwap = models.FloatField(blank=True, null=True)

    class Meta:
        managed = False
        db_table = 'xbtusd_hourly'

我的看法是:

class HourlyTickList(ListAPIView):
    serializer_class = HourlyTickSerializer
    def get(self, request):
        start = request.GET.get('start', None)
        end = request.GET.get('end', None)
        tz = pytz.timezone("Europe/Paris")

        start_dt = datetime.datetime.fromtimestamp(int(start) / 1000, tz)
        end_dt = datetime.datetime.fromtimestamp(int(end) / 1000, tz)

        qs = HourlyTick.objects.filter(timestamp__range = (start_dt, end_dt))
        rawData = serializers.serialize('python', qs)
        fields = [d['fields'] for d in rawData]
        fieldsJson = json.dumps(fields, indent=4, sort_keys=True, default=str)

        return HttpResponse(fieldsJson, content_type='application/json')

我收到的信息是:

RuntimeWarning:DateTimeField HourlyTick.timestamp收到未经验证的 时区支持处于活动状态时的日期时间(2017-01-15 06:00:00)。
运行时警告)

make_aware 要修复此错误,我将获得以下错误:

ValueError:非原始日期时间(tzinfo已设置)

我的数据库包含如下数据:

2017-01-06T12:00:00.000Z

我该如何解决这个问题?
