Django REST 框架多对多序列化器

Question

我有模型：

class Car: 
    name = models.CharField(max_length=50, blank=True, default='')


class Wheel:
    name = models.CharField(max_length=50, blank=True, default='')
    cars =  models.ManyToManyField(Car)

和序列化器：

class CarSerializer(serializers.ModelSerializer):
    class Meta: 
        model = Car
        fields = ('name')

class WheelSerializer(serializers.ModelSerializer):
    cars = CarSerializer(many=True, required=False)
    class Meta:
        model = Wheel
        fields = ('name', 'cars')

它在 Wheel case 上工作得很好，它向我展示了轮子和里面的汽车。但我想打电话给汽车，看看汽车里面的轮子。这是可能的？谢谢！

解决方案是创建新的序列化程序：

class CarSerializer(serializers.ModelSerializer):
    class Meta: 
         model = Car
         fields = ('name')

class WheelSerializer(serializers.ModelSerializer):
    class Meta:
        model = Wheel
        fields = ('name', 'cars')



class CarWheelSerializer(serializers.ModelSerializer):
        cars = CarSerializer(many=True, required=False)
        class Meta: 
            ....

和 WheelCarSerializer 一样。
