python之Django 使用 Django Rest Framework 创建自定义用户

我正在尝试使用 Django Rest Framework 创建自定义用户。我已经到了可以创建普通用户的地步，但我不确定如何将其扩展到自定义用户模型。

模型.py:

from django.db import models 
from django.contrib.postgres.fields import ArrayField 
from django.contrib.auth.models import User 
 
 
class UserProfile(models.Model): 
    user = models.OneToOneField(User, on_delete=models.CASCADE) 
    languages = ArrayField(models.CharField(max_length=30, blank=True)) 

序列化程序.py:

from rest_framework import serializers 
from django.contrib.auth.models import User 
 
 
class UserSerializer(serializers.ModelSerializer): 
    password = serializers.CharField(write_only=True) 
 
    class Meta: 
        model = User 
        fields = ('first_name', 'last_name', 'email', 'username', 'password') 
 
    def create(self, validated_data, instance=None): 
        user = super(UserSerializer, self).create(validated_data) 
        user.set_password(validated_data['password']) 
        user.save() 
        return user 

views.py:

@api_view(['POST']) 
@permission_classes((AllowAny,)) 
def create_user(request): 
    serialized = UserSerializer(data=request.data) 
    if serialized.is_valid(): 
        serialized.save() 
        return Response(serialized.data, status=status.HTTP_201_CREATED) 
    else: 
        return Response(serialized._errors, status=status.HTTP_400_BAD_REQUEST) 

如何将 languages 字段扩展到 UserSerializer 可以处理它的地方？每次创建 user 时都创建一个 signal，然后自动创建一个 userprofile 会更好吗？

请您参考如下方法:

您可以通过两种方式来实现，一种是创建配置文件序列化程序，另一种是不创建它。 使用序列化程序，

class UserProfileSerializer(serializers.ModelSerializer): 
    languages = serializers.ListField(child=serializers.CharField(max_length=30, allow_blank=True)) 
 
    class Meta: 
        model = UserProfile 
        fields = ('languages',) 
 
class UserSerializer(serializers.ModelSerializer): 
    password = serializers.CharField(write_only=True) 
    userprofile = UserProfileSerializer(required=False) 
 
    class Meta: 
        model = User 
        fields = ('first_name', 'last_name', 'email', 'username', 'password', 'userprofile') 
 
 
    def create(self, validated_data, instance=None): 
        profile_data = validated_data.pop('userprofile') 
        user = User.objects.create(**validated_data) 
        user.set_password(validated_data['password']) 
        user.save() 
        UserProfile.objects.update_or_create(user=user,**profile_data) 
        return user 

没有配置文件序列化器

class UserSerializer(serializers.ModelSerializer): 
    password = serializers.CharField(write_only=True) 
    languages = serializers.ListField(child=serializers.CharField(max_length=30, allow_blank=True), source="userprofile.languages") 
 
    class Meta: 
        model = User 
        fields = ('first_name', 'last_name', 'email', 'username', 'password', 'lanugages') 
 
 
    def create(self, validated_data, instance=None): 
        profile_data = validated_data.pop('userprofile') 
        user = User.objects.create(**validated_data) 
        user.set_password(validated_data['password']) 
        user.save() 
        UserProfile.objects.update_or_create(user=user,**profile_data) 
        return user
