类型对象'用户'没有属性'对象django

Question

我正在尝试使用 jwt 令牌从 api 获取用户列表，因此我生成了令牌并使用电子邮件并通过并尝试使用令牌发出获取请求，但我得到了这个错误：

File "/home/tboss/Desktop/environment/liveimages/backend/venv/lib/python3.7/site-packages/rest_framework_simplejwt/authentication.py", line 111, in get_user
user = User.objects.get(**{api_settings.USER_ID_FIELD: user_id})
rest_framework.request.WrappedAttributeError: type object 'User' has no attribute 'objects'

我已经创建了自定义用户

views.py：

from users.models import User
from rest_framework import viewsets
from rest_framework.decorators import api_view, permission_classes, authentication_classes  
from rest_framework.permissions import AllowAny, IsAuthenticated
from rest_framework.status import  (
HTTP_400_BAD_REQUEST,
HTTP_404_NOT_FOUND,
HTTP_200_OK)
from . import serializers
from rest_framework.response import Response
from rest_framework.authentication import TokenAuthentication, SessionAuthentication



class UserViewSet(viewsets.ModelViewSet):
queryset = User.object.all()
serializer_class = serializers.UserSerializers

settings.py：

REST_FRAMEWORK = {
'DEFAULT_AUTHENTICATION_CLASSES':(
    'rest_framework_simplejwt.authentication.JWTAuthentication',

),
'DEFAULT_PERMISSION_CLASSES':(
    'rest_framework.permissions.IsAuthenticated',
)

}

我正在使用 User.object 它工作正常 但是这个错误来自 jwt

用户模型.py：

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager, PermissionsMixin
from django.utils import timezone
from django.conf import settings
from django.db.models.signals import post_save
from django.dispatch import receiver
from rest_framework.authtoken.models  import Token


class UserManager(BaseUserManager):
def _create_user(self, email, password, is_staff, is_superuser, **extra_fields):
    if not email:
        raise ValueError('user must have email address')
    now = timezone.now()
    email = self.normalize_email(email)
    user = self.model(
        email=email,
        is_staff=is_staff,
        is_active=True,
        is_superuser=is_superuser,
        last_login=now,
        date_joined=now,
        **extra_fields
    )
    user.set_password(password)
    user.save(using=self._db)
    return user
def create_user(self, email, password, **extra_fields):
    return self._create_user(email, password, False, False, **extra_fields)

def create_superuser(self, email, password, **extra_fields):
    user=self._create_user(email, password, True, True, **extra_fields)
    user.save(using=self._db)
    return user

class User(AbstractBaseUser, PermissionsMixin):
   email = models.EmailField(max_length = 100, unique = True)
   First_Name = models.CharField(max_length = 100, null = True, blank = True)
   Last_Name = models.CharField(max_length = 100, null = True, blank = True)
  is_staff = models.BooleanField(default = False)
  is_superuser = models.BooleanField(default = False)
  is_active = models.BooleanField(default = True)
  last_login = models.DateTimeField(null = True, blank = True)
  date_joined = models.DateTimeField(auto_now_add=True)

  USERNAME_FIELD = "email"
  EMAIL_FIELD = "email"
  REQUIRED_FIELD = []

  object = UserManager()

def get_absolute_url(self):
    return "/users/%i/" % (self.pk)

Answer 1

我刚刚遇到了与 Token not User 相同的错误。

您需要将“rest_framework.authtoken”添加到您的 INSTALLED_APPS 并且不要忘记之后进行 manage.py 迁移。

这为我解决了问题。

Answer 2

我刚刚遇到同样的错误，并将以下几行添加到 settings.py 文件中。

SIMPLE_JWT = {
    'ROTATE_REFRESH_TOKENS': False,
    'BLACKLIST_AFTER_ROTATION': False,
    'UPDATE_LAST_LOGIN': False,
}

还将以下行添加到 settings.py 文件中。

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'corsheaders',
    'rest_framework',
    'rest_framework.authtoken',
    'rest_framework_simplejwt' #new line
]

同时运行这个命令：python manage.py migrate 现在，它正在工作。

Answer 3

检查此代码

    objects = MyUserManager()

没有对象=...

Answer 4

我用过这个，它对我有用

python manage.py 迁移
