删除Django超级用户

Question

这可能是个重复的问题，但我在其他地方找不到相关内容，所以我就问一下：

有没有什么简单的方法可以通过终端删除一个超级用户？就像Django中的createsuperuser命令那样？

Answer 1

这里有一个简单的自定义管理命令，你可以把它放在 myapp/management/commands/deletesuperuser.py 这个文件里：

from django.contrib.auth.models import User
from django.core.management.base import BaseCommand
from django.core.management.base import CommandError


class Command(BaseCommand):

    def add_arguments(self, parser):
        parser.add_argument('username', type=str)

    def handle(self, *args, **options):
        try:
            user = User.objects.get(username=options['username'], is_superuser=True)
        except User.DoesNotExist:
            raise CommandError("There is no superuser named {}".format(options['username']))

        self.stdout.write("-------------------")
        self.stdout.write("Deleting superuser {}".format(options.get('username')))
        user.delete()
        self.stdout.write("Done.")

其实不需要删除超级用户，只要再创建一个新的超级用户就可以了。你可以用和之前一样的名字来创建新的超级用户。我忘记了超级用户的密码，所以我就用之前的名字创建了一个新的超级用户。

这是给那些没有使用Django自带的用户模型，而是用自定义用户模型的人准备的答案。

class ManagerialUser(BaseUserManager):
    """ This is a manager to perform duties such as CRUD(Create, Read,
     Update, Delete) """

    def create_user(self, email, name, password=None):
         """ This creates a admin user object """

         if not email:
             raise ValueError("It is mandatory to require an email!")

         if not name:
             raise ValueError("Please provide a name:")

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

         """ This will allow us to store our password in our database
         as a hash """
         user.set_password(password)
         user.save(using=self._db)

         return user


    def create_superuser(self, email, name, password):
         """ This creates a superuser for our Django admin interface"""

         user = self.create_user(email, name, password)
         user.is_superuser = True
         user.is_staff = True
         user.save(using=self._db)

         return user


class TheUserProfile(AbstractBaseUser, PermissionsMixin):
    """ This represents a admin User in the system and gives specific permissions
 to this class. This class wont have staff permissions """

    # We do not want any email to be the same in the database.
    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)

    USERNAME_FIELD = 'email'

    REQUIRED_FIELDS = ['name',]

    # CLASS POINTER FOR CLASS MANAGER
    objects = ManagerialUser()

    def get_full_name(self):
        """ This function returns a users full name """

        return self.name

    def get_short_name(self):
        """ This will return a short name or nickname of the admin user
        in the system. """

        return self.name

    def __str__(self):
        """ A dunder string method so we can see a email and or
        name in the database """

        return self.name + ' ' + self.email

现在我们来看看如何删除系统中注册的超级用户：

python3 manage.py shell

>>>(InteractiveConsole)
>>>from yourapp.models import TheUserProfile
>>>TheUserProfile.objects.all(email="The email you are looking for", is_superuser=True).delete()

Answer 4

如果你使用的是自定义用户模型，那么它会是：

python manage.py shell

from django.contrib.auth import get_user_model
model = get_user_model()
model.objects.get(username="superjoe", is_superuser=True).delete()

Answer 5

虽然没有内置的命令，但你可以很简单地通过命令行来实现这个功能：

> python manage.py shell
$ from django.contrib.auth.models import User
$ User.objects.get(username="joebloggs", is_superuser=True).delete()
