創建自定義超級用戶后無法登錄 django 管理面板

Question

大家好，我盡力了，但我無法使用我的自定義用戶 model 登錄到 django 管理面板。我做了我能做的所有事情，我還對 email 和 rest 進行了身份驗證，但我仍然沒有能夠登錄到 django 管理面板，它一直在說：

請輸入正確的員工帳號email和密碼。 兩個地方都要注意大小寫。

我嘗試並檢查了我的密碼大概一百次了，但我仍然不讓我登錄。

有人可以幫我解決這個問題，這將是有史以來最大的幫助。 我已經被困在這里一個月了。

我已經粘貼了我在下面所做的所有代碼。

模型.py:

from django.db import models
import uuid
from django.utils import timezone
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, BaseUserManager
from django.utils.translation import gettext_lazy as _

class CustomAccountManager(BaseUserManager):

    def create_user(self, first_name, last_name, phone_number, email, password, **other_fields):

        if not email:
            raise ValueError(_('You must provie an email address'))

        if not first_name:
            raise ValueError(_('You must provide a first name'))

        if not last_name:
            raise ValueError(_('You must provide a last name'))

        email = self.normalize_email(email)
        user = self.model(email=email, first_name=first_name, last_name=last_name, phone_number=phone_number, **other_fields)
        user.set_password(password)
        user.save()
        return user

    def create_superuser(self, email, first_name, last_name, phone_number, password, **other_fields):
        other_fields.setdefault('is_staff', True)
        other_fields.setdefault('is_superuser', True)
        other_fields.setdefault('is_active', True)

        if other_fields.get('is_staff') is not True:
            raise ValueError(_('Superuser must be assigned to is_staff=True'))

        if other_fields.get('is_active') is not True:
            raise ValueError(_('Superuser must be assigned to is_active=True'))

        if other_fields.get('is_superuser') is not True:
            raise ValueError(_('Superuser must be assigned to is_superuser=True'))

        return self.create_user(email, first_name, last_name, password, phone_number, **other_fields)

class NewUser(AbstractBaseUser, PermissionsMixin):
    first_name = models.CharField(max_length=200, null=True, blank=True)
    last_name = models.CharField(max_length=200, null=True, blank=True)
    email = models.EmailField(max_length=200, null=True, blank=True, unique=True)
    password = models.CharField(max_length=200,null=True, blank=True)
    confirm_password = models.CharField(max_length=200, null=True, blank=True)
    phone_number = models.CharField(max_length=10,null=True, blank=True)
    address = models.TextField(null=True, blank=True)
    pin_code = models.CharField(null=True, max_length=6, blank=True)
    region = models.CharField(null=True, max_length=200, blank=True)
    state = models.CharField(null=True, max_length=100, blank=True)
    start_date = models.DateField(default=timezone.now)
    is_staff = models.BooleanField(default=False)
    is_active = models.BooleanField(default=False)
    id = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False) 

    objects = CustomAccountManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['first_name', 'last_name', 'phone_number']

    def __str__(self):
        return self.first_name + ' ' + self.last_name

身份驗證.py：

from .models import NewUser
from django.contrib.auth.backends import BaseBackend

class EmailAuthBackend(BaseBackend):
    model = NewUser
    def authenticate(self, request = None, email=None, password=None):
        try:
            user = self.model.objects.get(email=email)
        except self.model.DoesNotExist:
            return None
        if self.model.check_password(password) and user is not None:
            return user

    def get_user(self, user_id):
        try:
            return self.model.objects.get(id=user_id)
        except self.model.DoesNotExist:
            return None

admin.site.register(NewUser)

這就是這個自定義用戶 model 所需的所有代碼。請有人幫助我受夠了這個，就像真的受夠了一樣。

你可以試試這個：

在模型.py 中：

from django.contrib.auth.models import (
    AbstractBaseUser,
    BaseUserManager,
    PermissionsMixin,
)

class UserManager(BaseUserManager):
    '''Manager for users.'''

    def create_user(self, email, password=None, **extra_fields):
        '''Create, save and return a new user.'''
        if not email:
            raise ValueError('User must have an email address.')
        user = self.model(email=self.normalize_email(email), **extra_fields)
        user.set_password(password)
        user.save(using=self._db)

        return user

    def create_superuser(self, email, password):
        '''Create and return a new superuser.'''
        user = self.create_user(email, password)
        user.is_staff = True
        user.is_superuser = True
        user.save(using=self._db)

        return user

class User(AbstractBaseUser, PermissionsMixin):
    '''User in the system.'''
    email = models.EmailField(max_length=255, unique=True)
    name = models.CharField(max_length=255)
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)

    objects = UserManager()

    USERNAME_FIELD = 'email'

注意：這是基於 email 的登錄。
