DRF 中的过滤问题

Question

我遇到的问题如下： TypeError: init() 得到了一个意外的关键字参数 'name' "GET /apartmentimages/ HTTP/1.1" 500 136691

我有这样一个model.py class:

class Apartment(models.Model):
    apartment_title = models.CharField(max_length=200)
    apartment_description = models.TextField()
    apartment_location = models.CharField(max_length=200)
    apartment_people_quantity = models.PositiveIntegerField()
    apartment_price = models.CharField(max_length=200)
    apartment_type = models.CharField(max_length=50, null=True)
    
    def __str__(self):
        return self.apartment_title

class ApartmentImage(models.Model):
    apartment = models.ForeignKey(Apartment, on_delete=models.CASCADE)
    image = models.ImageField(upload_to='images/', null=True, blank=True)

和serializers.py class:

    class ApartmentSerializer(serializers.ModelSerializer):
    class Meta:
        model = Apartment
        fields = (
            'id',
            'url',
            'apartment_title', 
            'apartment_description', 
            'apartment_location', 
            'apartment_people_quantity', 
            'apartment_price',
            'apartment_type',
            )

class ApartmentImageSerializer(serializers.ModelSerializer):
    class Meta:
        model = ApartmentImage
        fields = ('id', 'url', 'apartment', 'image',)

在views.py中：

    apartment_id = django_filters.CharFilter(name="apartment__id",
                                            queryset=Apartment.objects.all())

    class Meta:
        model = ApartmentImage
        fields = ('apartment_id',)

class ApartmentImageView(viewsets.ModelViewSet):
    queryset = ApartmentImage.objects.all()
    serializer_class = ApartmentImageSerializer
    filter_backends = (DjangoFilterBackend,)
    filter_class = ApartmentImageFilter

Answer 1

您在 django-filters 中没有名称作为属性。也许你要找的是 field_name 而你也不需要 queryset=Apartment.objects.all()。如果您正在寻找 field_name 的字段，那么您的 CharFielter 应该看起来像这样 apartment_id = django_filters.CharFilter(field_name="apartment__id", lookup_expr='iexact') 如果您没有覆盖 id 生成，它可能应该是 NumberFilter() 如果我是没错。
