关于python：Django DateTimeField收到了一个天真的日期时间

Django DateTimeField received a naive datetime

我遇到的问题是我似乎无法根据时间戳(即日期和小时)过滤我的数据。

我的模型如下：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

# 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：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16

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')

我收到的消息是：

RuntimeWarning: DateTimeField HourlyTick.timestamp received a naive
datetime (2017-01-15 06:00:00) while time zone support is active.
RuntimeWarning)

但是，当我使用make_aware来修复此错误时，我收到错误：

ValueError: Not naive datetime (tzinfo is already set)

我的数据库包含如下所示的数据：

2017-01-06T12:00:00.000Z

出于某种原因，第一个选项返回结果，但它完全忽略了时间。

我该如何解决？
