问题描述

I am creating a custom User model and I am getting an error when I create my super user for the first time. Any advice, please. I would ideally like to user BOTH my username or email for verification interchangeably, but this may be a question for another day.

I started initially with email as my username_field but changed after a while. Please, can someone provide guidance, please? I have posted my models.py file which sits inside the accounts app.

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


class UserManager(BaseUserManager):
    def create_user(self, email,
                    username,
                    password=None,
                    is_active=True,
                    is_staff=False,
                    is_admin=False,
                    is_client=True,  # anyone registered can be a client
                    is_partner=False

                    ):
        if not username:
            raise ValueError("Unique username is required")
        if not email:
            raise ValueError("User must have an email address")
        if not password:
            raise ValueError("Password is required")
        user_obj = self.model(
            email=self.normalize_username(username)
        )
        user_obj.set_password(password)  # change user password
        user_obj.username = username
        user_obj.email = email
        user_obj.staff = is_staff
        user_obj.client = is_client
        user_obj.partner = is_partner
        user_obj.admin = is_admin
        user_obj.active = is_active
        user_obj.save(using=self._db)
        return user_obj

    def create_staff_user(self, username, password=None):
        user = self.create_user(
            username,
            password=password,
            is_staff=True
        )
        return user

    def create_partner_user(self, username, password=None):
        user = self.create_user(
            username,
            password=password,
            is_partner=True
        )
        return user

    def create_client_user(self, username, password=None):
        user = self.create_user(
            username,
            password=password,
            is_client=True
        )
        return user

    def create_superuser(self, username, password=None):
        user = self.create_user(
            username,
            password=password,
            is_staff=True,
            is_admin=True
        )
        return user


class User(AbstractBaseUser):
    username = models.CharField(unique=True, max_length=255)
    full_name = models.CharField(max_length=255, blank=True, null=True)
    email = models.EmailField(unique=True, max_length=255)
    active = models.BooleanField(default=True)  # can login
    staff = models.BooleanField(default=False)  # staff user non super
    admin = models.BooleanField(default=False)  # superuser
    timestamp = models.DateTimeField(auto_now_add=True)

    USERNAME_FIELD = 'username'  # username
    REQUIRED_FIELDS = []  #['full_name']

    objects = UserManager()

    def __str__(self):
        return self.username

    def get_full_name(self):
        return self.username

    def get_short_name(self):
        return self.username

    @property
    def is_staff(self):
        return self.staff

    @property
    def is_partner(self):
        return self.partner

    @property
    def is_client(self):
        return self.client

    @property
    def is_admin(self):
        return self.admin

    @property
    def is_active(self):
        return self.active

The error from shell is as below

查看您的代码:

def create_superuser(self, username, password=None):
    user = self.create_user(
        username,
        password=password,
        is_staff=True,
        is_admin=True
    )
    return user

你没有设置username。它应该是:

def create_superuser(self, username, password=None):
    user = self.create_user(
        username = username,
        password=password,
        is_staff=True,
        is_admin=True
    )
    return user

此外,您可以尝试对电子邮件和用户名注册进行此操作:

def create_superuser(self, username=None, email=None, password=None):
        user = self.create_user(
            username = username,
            email = email.
            password=password,
            is_staff=True,
            is_admin=True
        )
        return user
