我正在使用 django Rest 框架在 django 中编写基于 token 的身份验证 API。
我已经使用默认的User模型实现了它。但我需要在用户模型中添加更多细节。
经过搜索，找到了AbstractBaseUser、BaseUserMANager。我也实现了它并为其编写了序列化器，但出现错误。
网上有太多不同的方法，现在我很困惑哪一种是正确的方法。
models.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
序列化器.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
views.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"})

我使用 django 和 drf 文档编写了大部分代码(也有一些博客)。错误位于 serializer.save()
最佳答案
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，您的序列化程序将包含创建此用户实例所需的所有字段。
