Question

以下是我尝试实施的身份验证模型：

from django.db import models
from django.contrib.auth.models import AbstractBaseUser
from django.contrib.auth.models import BaseUserManager
# Create your models here.


class AccountManager(BaseUserManager):

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

        account.set_password(password)
        account.save()

        return account

    def create_superuser(self, username, password, **kwargs):
        account = self.create_superuser(username, password, **kwargs)
        account.is_admin = 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)

    USERNAME_FIELD = 'username'

    objects = AccountManager()

当我从终端运行createsuperuser命令时，它会抛出此错误

  ...................
  File "../models.py", line 22, in create_superuser
    account = self.create_superuser(username, password, **kwargs)
  File "../models.py", line 22, in create_superuser
    account = self.create_superuser(username, password, **kwargs)
RuntimeError: maximum recursion depth exceeded while calling a Python object

Answer 1

create_superuser上的AccountManager方法调用自身会导致无限递归，因为Python具有最大递归深度，无限递归在到达时会被异常停止。

您可能想要做的是：

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

    return account

自定义身份验证模型中的最大递归错误
