django 根据用户名注销用户

Question

我正在尝试强制注销不再活跃的 django 用户。我需要能够通过用户名强制用户注销。在做了一些研究之后，我发现 django 可以选择使用 logout(request) 注销，但它没有给我选择基于用户名的注销选项。 有人有任何想法吗？ 谢谢

我已尝试针对我的问题测试以下代码，该代码取自How to force user logout in django? 在我的模型中：

from django.contrib.auth.models import User
from django.db import models
from datetime import datetime

class MyUser(User):
force_logout_date = models.DateTimeField(null=True, blank=True)

def force_logout(self):
    self.force_logout_date = datetime.now()
    self.save()

然后我在views.py中添加了这部分：

from myapp.models import MyUser
MyUser.objects.get(username='johndoe').force_logout()

但我现在有以下错误：

MyUser matching query does not exist.

这主要取决于您如何进行身份验证。不知道确切的答案是不可能给你答案的。

但是，假设您使用的是默认的 Django 身份验证，这个答案应该仍然有效：
