Django rest framework：如何过滤范围内的查询集？

Question

我需要从 get 请求中过滤范围内的数据：

这是我的代码：

model.py

class MainModel(TimeStampedModel):
    model_name = models.CharField(_("model_name"), max_length=240)        
    model_price = models.DecimalField(_("model_price"), max_digits=8)

class ModelAdditionalData_1(TimeStampedModel):
    model_id = models.OneToOneField(
        Model,
        verbose_name=_('related model'),
        on_delete=models.CASCADE,
        related_name='model_water_flow_data1',
        related_query_name='model_water_flow_data1'
    )
    model_param_1 = models.models.DecimalField(_("model_param_1"), max_digits=8)

class ModelAdditionalData_2(TimeStampedModel):
    model_id = models.OneToOneField(
        Model,
        verbose_name=_('related model'),
        on_delete=models.CASCADE,
        related_name='model_water_flow_data2',
        related_query_name='model_water_flow_data2'
    )
    model_param_2 = models.models.DecimalField(_("model_param_2"), max_digits=8)

view.py :

class ModelsViewSet(ReadOnlyModelViewSet, GenericViewSet):
    serializer_class = ModelsSerializer

    def get_queryset(self):
    model_param_1 = self.request.query_params.get('model_param_1')
    model_param_2 = self.request.query_params.get('model_param_2')

    filters = {}
    if model_param_1:
        filters['model_water_flow_data1__model_param_1'] = model_param_1
    if model_param_2:
        filters['model_water_flow_data2__model_param_2'] = model_param_2

    if filters:
        return MainModel.objects.filter(**filters)

    return MainModel.objects.all()

我如何应用过滤器来过滤范围内的数据？例如，我不会按 1 和 10 之间的 model_param_1 过滤数据。

可以像这样构建过滤器以覆盖范围：

filters = {}

if model_param_1:
    filters['model_water_flow_data1__model_param_1__gte'] = 1
    filters['model_water_flow_data1__model_param_1__lte'] = 10

if model_param_2:
    filters['model_water_flow_data1__model_param_2__gte'] = 1
    filters['model_water_flow_data1__model_param_2__lte'] = 10

MainModel.objects.filter(**filters)
