此字段必须是 Django Rest Framework 中 OnetoOneField 邮递员中的唯一错误

如何解决此字段必须是 Django Rest Framework 中 OnetoOneField 邮递员中的唯一错误

我正在尝试使用嵌套序列化更新客户资料，同时更新主要的 Customuser first_name 和 last_name 字段。但我收到客户字段必须是唯一的错误。

我已经把照片贴在这里了。

我的模型：

class CustomUser(AbstractUser):
    # username = None
    first_name = models.CharField(max_length=255,verbose_name="First name")
    last_name = models.CharField(max_length=255,verbose_name="Last name")
    email = models.EmailField(unique=True)
    
    is_seller = models.BooleanField(default=False)
    is_customer = models.BooleanField(default=False)

    USERNAME_FIELD = "email"
    REQUIRED_FIELDS = ["first_name","last_name"]

    objects = CustomUserManager()

    def __str__(self):
        return self.email


class Customer(models.Model):
    customer = models.OneToOneField(settings.AUTH_USER_MODEL,on_delete=models.CASCADE,blank=True,null=True)
    full_name = models.CharField(max_length=100,blank=True)
    phone_num = models.CharField(max_length=50,blank=True)
    #dob = models.CharField(max_length=255,null=True)
    region = models.CharField(max_length=255,null=True)
    city = models.CharField(max_length=255,null=True)
    area = models.CharField(max_length=255,null=True)
    address = models.CharField(max_length=255,null=True)


    def __str__(self):
        return self.customer.email

我的序列化程序：

class CustomerProfileSerializer(serializers.ModelSerializer):
    class Meta:
        model = Customer
        fields = '__all__'
        # depth = 1


class CustomerUpdateSerializer(serializers.ModelSerializer):
    customer = CustomerProfileSerializer()
    class Meta:
        model = User
        fields = ('id',"first_name","last_name",'customer')

    def update(self,request,instance,validated_data):
        user = self.request.user
        instance.user.first_name=user.get('first_name')
        instance.user.last_name = user.get('last_name')
        instance.user.save()
        customer_data = validated_data.pop('customer',None)
        if customer_data is not None:
            instance.customer.region = customer_data['region']
            instance.customer.city = customer_data['city']
            instance.customer.area = customer_data['area']
            instance.customer.address = customer_data['address']
            instance.customer.save()
        return super().update(instance,validated_data)

我的观点：

class CustomerUpdateView(UpdateAPIView):
    permission_classes = [IsAuthenticated]
    queryset = User.objects.all()
    serializer_class = CustomerUpdateSerializer

该 url 在邮递员放置请求中可见。我已经在邮递员中发送了原始 json 数据，但它抛出了这个错误。如何更新客户模型中的这 4 个字段和 User 模型中的 2 个字段（first_name 和 last_name）？？

解决方法

在对序列化程序进行一些更改后，我的代码可以工作了。

这是工作代码：

class CustomerUpdateSerializer(serializers.ModelSerializer):
    customer = CustomerProfileSerializer(many=False)
    class Meta:
        model = User
        fields = ('id',"first_name","last_name",'customer')
        depth = 1

    def update(self,instance,validated_data):
        user = self.context['request'].user
        user.first_name = validated_data.get('first_name')
        user.last_name = validated_data.get('last_name')
        user.save()
        customer_data = validated_data.pop('customer',None)
        if customer_data is not None:
            instance.customer.region = customer_data['region']
            instance.customer.city = customer_data['city']
            instance.customer.area = customer_data['area']
            instance.customer.address = customer_data['address']
            instance.customer.save()
        return super().update(instance,validated_data)

这是因为我使用的是用户实例和客户模型的相同实例。现在，我分别获取字段 first_name 和 last_name 并仅将实例用于客户。它起作用了。
