Question

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

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

我想将数据发布到UserProfileList
格式如：

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

（＆＃39;用户名＆＃39;，＆＃39;电子邮件＆＃39;，＆＃39;密码＆＃39;来自User型号 secret_id来自UserProfile）

它可以在User和UserProfile表格中保存数据是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')

Answer 1

是的，有可能实现这一目标。

为了能够访问username中的email，password和UserProfileSerializer字段，您需要在其上定义这些字段，否则，序列化程序的字段验证将抛出未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，明确定义的字段为write_only，因此在阅读时它们不会显示。

上述代码将确保您不会在序列化程序的validated_attrs和.create()方法中从.update()中删除这些字段。

在此之后你有2个选项

选项＃1

您需要覆盖.create()的{{1}}方法，以便在UserProfileSerializer模型之外创建User模型。

UserProfile

选项＃2

您可以在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, ...)创建过程中处理UserProfile的创建（请参阅handling saving related instances in model manager classes）。为此，您需要定义自定义User类。

UserManager

django restframework generics.ListCreateAPIView可以处理一对一的字段吗？
