问分页与多条件紊乱导致接口404问题？

class SysAuditFilter(FilterSet):
    action_type = filters.CharFilter(
        field_name="action_type", lookup_expr="icontains", required=False
    )  # 模糊查询
    user_name = filters.CharFilter(
        field_name="user_name", lookup_expr="icontains", required=False
    )  # 模糊查询

    class Meta:
        model = SysAudit
        fields = ['action_type', 'user_name']  # 定义可用的过滤字段


# 定义视图集
class SysAuditViewSet(viewsets.ModelViewSet):
    queryset = SysAudit.objects.all()
    serializer_class = SysAuditSerializer
    filter_backends = (DjangoFilterBackend, OrderingFilter)  # 使用过滤器和排序
    ordering_fields = ('action_time',)

    def get_queryset(self):
        queryset = super().get_queryset()  # 获取初始查询集
        date_range = self.request.GET.getlist('dateRange[]')  # 获取日期范围参数

        # 调试输出，查看收到的参数
        print("日期范围参数：", date_range)

        # 处理日期范围过滤
        if len(date_range) == 2:  # 确保有两个时间点
            start_time, end_time = date_range
            queryset = queryset.filter(action_time__gte=start_time, action_time__lte=end_time)
        elif not date_range:  # 如果没有日期范围，则返回所有数据
            print("日期范围为空，返回所有数据")
        # user_name = self.request.GET.get('user_name', None)
        # if user_name:
        #     queryset = queryset.filter(user_name__icontains=user_name)
        # action_type = self.request.GET.get('action_type', None)
        # if action_type:
        #     queryset = queryset.filter(action_type__icontains=action_type)
        # 打印调试信息，查看过滤后的查询集
        print("过滤后的查询集：", queryset)

        # 返回最终的查询集，分页器会在后面处理
        return queryset
