Question

我有自定义的用户模型，这是模型：

from django.db import models
from django.contrib.auth.models import AbstractBaseUser
from django.contrib.auth.models import BaseUserManager


class AccountManager(BaseUserManager):

    def create_user(self, username=None, password=None, **kwargs):
        account = self.model(username=username)

        account.set_password(password)
        account.is_stuff = False
        account.save()

        return account

    def create_superuser(self, username, password, **kwargs):
        account = self.create_user(username, password, **kwargs)
        account.is_admin = True
        account.is_staff = True
        account.save()

        return account


class Account(AbstractBaseUser):
    username = models.CharField(max_length=40, unique=True)
    is_admin = models.BooleanField(default=False)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    initialized = models.BooleanField(default=False)

    USERNAME_FIELD = 'username'

    objects = AccountManager()

然后当我尝试获取所有用户的列表时，它会抛出AttributeError: 'Account' object has no attribute 'is_staff'。

class GetUserList(ListAPIView):
    permission_classes = (permissions.IsAdminUser,)
    queryset = Account.objects.all()
    serializer_class = AccountSerializer

Answer 1

IsAdminUser调用is_staff，它是在django的auth用户模型上定义的。因此，如果您有自己的自定义用户模型，则还需要为此提供实现

在django的A课程中，它是一个BooleanField，您可以看到here

Answer 2

在定义自己的权限后解决了问题：

class IsAdminUser(permissions.BasePermission):

    def has_permission(self, request, view):
        return request.user.is_admin

然后

class GetUserList(ListAPIView):
    permission_classes = (IsAdminUser,)
    queryset = Account.objects.all()
    serializer_class = AccountSerializer

Answer 3

正如@Sayse和@Daniel指出的那样，您可以通过将is_staff字段添加到自定义用户模型来解决此问题：

is_staff = models.BooleanField(_('staff status'),default=False)

（这对我有用）

Answer 4

对我来说，这是通过将这两个模型添加进来的

 is_staff = models.BooleanField(default=False)
 is_superuser = models.BooleanField(default=False)

然后在管理器中

def create_user(self, email, password=None):
        """
        Creates and saves a User with the given email and password.
        """
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

def create_superuser(self, email, password):
        """
        Creates and saves a superuser with the given email and password.
        """
        user = self.create_user(
            email,
            password=password,
        )
        user.is_staff = True
        user.is_superuser = True
        user.save(using=self._db)
        return user

这在Django 3中有效。

Answer 5

我将Django的版本更改为较早的版本 'pip install django == 2.2' 对我有用。

AttributeError：＆＃39;帐户＆＃39;对象没有属性＆＃39; is_staff＆＃39;
