Question

我有这样的模特：

class Car(models.Model):
    name = models.CharField(max_length=255)


class CarImage(models.Model):
    car = models.ForeignKey(Car, related_name='photos')
    photo = models.ImageField(upload_to='car/')

对于我有的序列化器：

class CarImageSerializer(serializer.ModelSerializer):
    class Meta:
        model = CarImage

class CarSerializer(serializer.ModelSerializer):
    photos = CarImageSerializer()
    class Meta:
        model = Car
        fields = ('id', 'name', 'photos',)

当CarSerializer的网页界面加载时，我默认会在non_field_errors字段上获得photos。这种事情是DRF支持的吗？如果不是最好的方法是什么？ P.S我使用通用CreateAPIView

Answer 1

使用docs，您应该采用其他方式：

class CarSerializer(serializer.ModelSerializer):
    photos = serializers.RelatedField(many=True)
    class Meta:
        model = Car
        fields = ('id', 'name', 'photos',)

Answer 2

也许你可以试试这个：

<强> serializers.py

class CarImageSerializer(serializers.ModelSerializer):

    class Meta:
        model = CarImage


class CarSerializer(serializers.HyperlinkedModelSerializer):
    photos = serializers.HyperlinkedRelatedField(many=True,
                                                 view_name='carimage-list')

    class Meta:
        model = Car
        fields = ('id', 'name', 'photos',)

<强> views.py

class CarImageList(ListCreateAPIView):
    queryset = CarImage.objects.all()
    serializer_class = CarImageSerializer


class CarList(ListCreateAPIView):
    queryset = Car.objects.all()
    serializer_class = CarSerializer

<强> urls.py

url(r'^carimage/$', CarImageList.as_view(), name='carimage-list'),
url(r'^car/$', CarList.as_view(), name='car-list'),

你应该注意所有需要的进口。不能保证，但你可以尝试一下。
