DjangoRest序列化程序：保存Foreignkey关系并序列化

我不熟悉Django rest和序列化程序的概念

我有这种数据库结构

用户1->N地址， 用户1->N电话

User

是django.contrib.auth.models.User<代码>地址和电话两种型号都包含此字段

user\u id=models.ForeignKey（user，on\u delete=models.CASCADE）

在我的UserSerializer中，如下所示

class UserSerializer(serializers.ModelSerializer):

    address = AddressSerializer(many=False)
    phone = PhoneSerializer(many=False)

    class Meta:
        model = User
        fields = (
            'id', 'username',
            'first_name', 'last_name',
            'email', 'password',
            'address', 'phone')

    def create(self, validated_data):
        # Save user.
        user = User.objects.create(
                first_name=validated_data['first_name'],
                last_name=validated_data['last_name'],
                username=validated_data['username'],
                email=validated_data['email'],
            )
        user.set_password(validated_data['password'])
        user.save()
        # User's address
        address_data = validated_data['address']
        address_data['user_id'] = user.id
        address = Address.objects.create(**address_data)
        # User's phone
        phone_data = validated_data['phone']
        phone_data['user_id'] = user.id
        phone = Phone.objects.create(**phone_data)
        return user

def create(self, validated_data):
    password = validated_data.pop('password')
    validated_data['username'] = validated_data['email']
    user = User.objects.create(**validated_data)
    user.set_password(password)
    user.save()
    return user

和地址序列化程序：

class AddressSerializer(serializers.ModelSerializer):
    class Meta:
        model = Address
        fields = (
                'user_id', 'address', 'pin_code', 'state', 'city', 'country')

我能够创建

用户

，但在执行

序列化程序时，数据

出现以下错误：

AttributeError: Got AttributeError when attempting to get a value for field `address` on serializer `UserSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `User` instance.
Original exception text was: 'User' object has no attribute 'address'.

编辑：

我的

create

方法如下所示

class UserSerializer(serializers.ModelSerializer):

    address = AddressSerializer(many=False)
    phone = PhoneSerializer(many=False)

    class Meta:
        model = User
        fields = (
            'id', 'username',
            'first_name', 'last_name',
            'email', 'password',
            'address', 'phone')

    def create(self, validated_data):
        # Save user.
        user = User.objects.create(
                first_name=validated_data['first_name'],
                last_name=validated_data['last_name'],
                username=validated_data['username'],
                email=validated_data['email'],
            )
        user.set_password(validated_data['password'])
        user.save()
        # User's address
        address_data = validated_data['address']
        address_data['user_id'] = user.id
        address = Address.objects.create(**address_data)
        # User's phone
        phone_data = validated_data['phone']
        phone_data['user_id'] = user.id
        phone = Phone.objects.create(**phone_data)
        return user

def create(self, validated_data):
    password = validated_data.pop('password')
    validated_data['username'] = validated_data['email']
    user = User.objects.create(**validated_data)
    user.set_password(password)
    user.save()
    return user

如果没有明确指定

相关名称

，则应调用地址和电话字段

地址集

和

电话集

class UserSerializer(serializers.ModelSerializer):
    address_set = AddressSerializer(many=False)
    phone_set = PhoneSerializer(many=False)

    class Meta:
        model = User
        fields = (
            'id', 'username',
            'first_name', 'last_name',
            'email', 'password',
            'address_set', 'phone_set'
        )

对不起，我没听懂。你能给你的答案添加一个例子吗？我得到一个错误：字段“phone”在serializer UserSerializer上声明，但没有包含在“fields”选项中。@De̳̳ath stalle̳r̳是的。字段也应称为地址集。请参阅Updateum。。。新错误

TypeError:“address_set”是此函数的无效关键字参数

@De̲̳ath stalle̳r向您的帖子添加完整的错误跟踪我的答案解决了您的问题了吗？您在我的答案的评论中没有看到我的回复通知吗？@SardorbekImomaliev我看到通知了。抱歉，我没有检查浏览器。只是检查一下，我想可能是通知有问题，因为您的用户名中有unicode latters
