具有基于令牌的身份验证django的自定义用户模型

Question

我正在为django-usign-djano-rest框架中基于令牌的身份验证编写API。我已经使用默认的User模型实现了它。但是我需要在用户模型中添加更多的细节。经过搜索，我找到了AbstractBaseUser，BaseUserMAnager。我也实现了它，并为它编写了Serializer，但出现了错误。网上有太多不同的方法，现在我很困惑哪种方法是正确的。

型号.py

from django.contrib.auth.models import AbstractBaseUser, BaseUserManager
class MyUserManager(BaseUserManager):
    def create_user(self, email, password):
        if not email:
            raise ValueError('Enter email')
        user = self.model(
            email=email.normalize_email(email)
        )
        user.set_password(password)
        user.save(using=self._db)
        return user
    def create_superuser(self, email, password):
        user = self.create_user(email, password=password)
        user.save(using=self._db)
        return user

class MyUser(AbstractBaseUser):
    email = models.EmailField(verbose_name='email address', max_length=255, unique=True, db_index=True)
    created = models.DateTimeField(auto_now_add=True)
    is_active = models.BooleanField(default=True)
    USERNAME_FIELD = 'email'
    objects = MyUserManager()
    def get_short_name(self):
        return self.email
    def get_full_name(self):
        return self.email
    def __unicode__(self):
        return self.email

序列化程序.py

from rest_framework import serializers
from bsa.models import MyUser
from django.contrib.auth import get_user_model

class UserSerializer(serializers.ModelSerializer):
    password = serializers.CharField(style={'input_type': 'password'})
class Meta:
    model = get_user_model()
    fields = ['email', 'password']
    def create(self, email, password):
        user = MyUser(email, password)
        user.set_password(password)
        user.save()
        return user

视图.py

from bsa.serializers import UserSerializer
from rest_framework.decorators import APIView
from rest_framework.response import Response
class Test(APIView):
    def post(self, request):
        serializer = UserSerializer( data=request.data)
        if serializer.is_valid():
            #getting error here
            serializer.save()
            return Response({'detail': "POST Response"})
        return Response({'detail': "Response"})

如果我从"serializers.py"中的create方法中删除self的错误更改

我已经使用django和drf文档（一些博客也是如此）编写了大部分代码。错误在serializer.save() 中

Answer 1

我看到的第一个错误是def create(self, email, password)应该接收参数self和validated_data。例如：

def create(self, validated_data):
    """Create a new model instance"""
    return MyUser.objects.create(**validated_data)

理想情况下，序列化程序将包含创建该用户实例所需的所有字段。
