我有一个模型UserProfile ，它有一个与Django用户模型相关的OneToOneField
我在view.py中有UserProfileList

class UserProfileList(generics.ListCreateAPIView):
        queryset = UserProfile.objects.all()
        serializer_class = UserProfileSerializer

我想要将数据发布到UserProfileList
格式如下：

{   "username":"username",
    "email":"email@email",
    "password":"password",
    "secret_id":1
}

（'用户名'，'电子邮件'，'密码'来自User模型secret_id来自UserProfile ）

它可以将数据保存在User和UserProfile表中
它是否是posibble？

models.py

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    secret_id=models.IntegerField(default=0)

views.py

from rest_framework import generics
from django.contrib.auth.models import User
from .serializers import UserProfileSerializer, UserSerializer
from account.models import UserProfile

class UserList(generics.ListCreateAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer

class UserDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = User.objects.all()
    serializer_class = UserSerializer

class UserProfileList(generics.ListCreateAPIView):
    queryset = UserProfile.objects.all()
    serializer_class = UserProfileSerializer

class UserProfileDetail(generics.RetrieveUpdateDestroyAPIView):
    queryset = UserProfile.objects.all()
    serializer_class = UserProfileSerializer

serializer.py

from django.contrib.auth.models import User
from rest_framework import serializers
from account.models import UserProfile


    class UserProfileSerializer(serializers.HyperlinkedModelSerializer):
        class Meta:
            model = UserProfile
            fields = ('user','secret_id')

    class UserSerializer(serializers.HyperlinkedModelSerializer):
        class Meta:
            model = User
            fields = ('username','email','password')

是的，这是可能的。

为了能够访问UserProfileSerializer的username ， email和password字段，您需要在其上定义这些字段，否则，序列化程序的验证将会抛出没有在序列化程序中定义的字段：

class UserProfileSerializer(serializers.HyperLinkedModelSerializer):
    email = serializers.CharField(write_only=True)
    username = serializers.CharField(write_only=True)
    password = serializers.CharField(write_only=True)

    class Meta:
        ...

请注意，显式定义的字段是write_only ，因此在读取时它们不会显示出来。

上面的代码会向你保证这些字段不会从你的序列化器的.create()和.update()方法中的validated_attrs中消除。

之后你有2个选项

选项1

您需要覆盖UserProfileSerializer的.create()方法，以创建除UserProfile模型以外的User模型。

class UserProfileSerializer(serializers.HyperLinkedModelSerializer):
    # above definitions

    def create(self, validated_attrs):
        # now you have here the email, username and password arguments 
        email = validated_attrs.pop('email', None)
        username = validated_attrs.pop('username', None)
        password = validated_attrs.pop('password', None)

        # your creation logic here
        user = User.objects.create(...)
        user_profile = UserProfile.objects.create(user=user, ...)

选项＃2

您可以在User创建过程中处理UserProfile的创建（请参阅处理在模型管理器类中保存相关实例）。 为此，您需要定义一个自定义的UserManager类。

class UserManager(models.Manager):
...

def create(self, username, email, secret_id=None):
    user = User(username=username, email=email)
    user.save()
    user_profile = UserProfile(
        user=user,
        secret_id=secret_id
    )
    user_profile.save()
    return user
