如何使用Django Rest框架过滤器创建日期时间过滤器

我正在尝试创建datetime筛选器，但我的类没有按预期工作。我曾经这样做过。我没有收到任何错误，但我也没有收到任何错误，这是我的筛选器类：

import rest_framework_filters as filters
from core import models

class FeedFilter(filters.FilterSet):
    timestamp_gte  = filters.DateTimeFromToRangeFilter()
    class Meta:
        model = models.MQTTFeedWeather
        fields = {
            'created_at': ('lte', 'gte')
        }

模型类：

class MQTTFeedWeather(models.Model):
    sensor = models.ForeignKey(
        'SensorDevice',
        on_delete = models.CASCADE
    )
    feed = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

我的看法是：

class DeviceFeedListAPI(generics.ListAPIView):
    authentication_classes = (authentication.TokenAuthentication,)
    permission_classes = (permissions.IsAuthenticated, permissions.IsAuthenticated,)
    queryset = models.MQTTFeedWeather.objects.all()
    serializer_class = serializers.WeatherFeedSerializer
    pagination_class = pagination.PostLimitOffsetPagination
    filter_backends = (DjangoFilterBackend,OrderingFilter,SearchFilter)
    filter_class = filters.FeedFilter
    search_fields = ('feed',)

我想在表中创建的_上创建一个日期时间筛选器。当我运行url时：

它不过滤数据。谁能帮我一下我做错了什么！！谢谢

嗨，你可以这样试试

class FeedFilter(django_filters.rest_framework.FilterSet):
    start_date = django_filters.DateTimeFilter(field_name='created_at', lookup_expr='gte')
    end_date = django_filters.DateTimeFilter(field_name='created_at', lookup_expr='lte')

    class Meta:
        model = MQTTFeedWeather
        fields = ('start_date', 'end_date')
