Django-filter Choice Filter 无法识别现有字段

Question

我正在尝试应用 ChoiceFilter，但它好像我所指的字段没有被识别，但它确实存在：

模型视图集：

class StartUpViewSet(NestedViewSetMixin, ModelViewSet):
    """
      Class that provides List, Retrieve, Create, Update, Partial Update and Destroy  actions for startups.
      It also include a filter by startup status
    """
    model = Startup
    queryset = Startup.objects.all()
    serializer_class = StartupSerializer
    filter_backends = (filters.DjangoFilterBackend,)
    filterset_fields = 'status'

过滤类：

class StartupFilter(filters.FilterSet):
    status = filters.ChoiceFilter(choices=START_UP_STATUS)

    class Meta:
        model = Startup
        fields = ['status']

和型号：

class Startup(models.Model):
    header = models.CharField("Header", max_length=255)
    title = models.CharField("Title", max_length=255)
    description = models.CharField("description", max_length=255)
    # TODO Change this to options instead of array
    tags = ArrayField(models.CharField(max_length=10, blank=True), size=5)
    # TODO Images to be stored in aws only url will be in DB
    card_image = models.ImageField(upload_to='media/images/cards')
    logo_image = models.ImageField(upload_to='media/images/logos')
    main_img = models.ImageField(upload_to='media/images/main', null=True)
    createdAt = models.DateTimeField("Created At", auto_now_add=True)
    status = models.IntegerField(choices=START_UP_STATUS, default=1)

    def __str__(self):
        return self.title

错误：

'Meta.fields' must not contain non-model field names: s, t, a, u

Answer 1

正如名称 filtered_fields 所暗示的那样，它需要一个集合字段，而不是单个字段。因此，您应该将其实现为列表、元组、集合或任何其他字符串集合，而不是单个字符串：

class StartUpViewSet(NestedViewSetMixin, ModelViewSet):
    # …
    <strong>filterset_fields = ('status',)</strong>

如果您想指定自定义 FilterSet，您可以通过以下方式传递对 class 的引用：

class StartUpViewSet(NestedViewSetMixin, ModelViewSet):
    # no filterset_fields
    <strong>filterset_class = StartupFilter</strong>
