Django项目单字段区间查询的实现

	class CustomDateTimeFromToRangeFilter(filters.DateTimeFromToRangeFilter):
	    def filter(self, qs, value):
	        if value and value.stop:
	            new_value = slice(value.start, value.stop + timedelta(days=1))
	            return super().filter(qs, new_value)
	        return super().filter(qs, value)
	
	
	class ComputerFileter(filters.FilterSet):
	    create_time = CustomDateTimeFromToRangeFilter()
	
	    class Meta:
	        model = ComputerStatusRecord
	        fields = '__all__'

	class ComputerSerializer(ModelSerializer):
	    create_time = serializers.DateTimeField(format="%Y-%m-%d %H:%M:%S", read_only=True)	
	    # 注意重写之后需要添加read_only要不然models.py里面的设置的属性没用了
	
	    class Meta:
	        model = ComputerStatusRecord
	        fields = "__all__"

                           'over_kill_rate', 'miss_rate']:
            after = self.request.query_params.get(f'{field_name}_after')	# 可以根据自己的需求而定
            before = self.request.query_params.get(f'{field_name}_before')

                filters[f'{field_name}__gte'] = after
