Django注册：如何允许用户删除其帐户？ [英] Django-registration: How to allow user delete their account?

问题描述

我有一个简单的网站，用户可以在其中注册以便访问私人内容并接收新闻通讯。我已经使用 django-registration 进行用户注册和身份验证，并使用了一些HTML模板此处。

整个系统正在运行（登录，注销，密码恢复等），但我意识到用户无法从网站上删除其帐户。是否为此设计了一个插件，或者如何扩展注册类来做到这一点？删除后，我宁愿使用真正的抑制方式，而不仅仅是让用户处于非活动状态。

解决方案

您可以执行以下操作：

  def delete_user（请求，用户名）：
 context = {} 
 
 try：
u = User.objects.get（username = username）
 u.delete （）
 context ['msg'] ='用户已删除。'
，除了User.DoesNotExist：
 context ['msg'] ='用户不存在。'
例外，例如e：
 context ['msg'] = e.message 
 
 return render（request，'template.html'，context = context）
  

，并具有以下网址格式：

  url（r'^ delete /（？P< username> [\w | \W .-] +）/ $'，views.delete_user，name ='delete-user'）
   
 
这将完成工作。 
 
 
 但是，如文档说：
 
 
  is_active  
 
 
布尔值。指定是否应将此用户帐户视为活动帐户。 我们建议您将此标志设置为 False 而不是删除帐户；这样，如果您的应用程序具有用户的任何外键，则外键不会中断。
 
 
将用户设置为不活动而不是将其完全从数据库中删除，因为外键会中断。
 
 
因此，您可以简单地执行以下操作：
  def delete_user（请求，用户名）：
 context = {} 
 
 try：
 user = User.object.get（username = username）
 user.is_active = False 
 user.save（）
 context ['msg'] ='配置文件已成功禁用。'
，除了User.DoesNotExist：
＃... 
，但例外为e：
＃... 
 
＃... 
  
由于现在每个人都可以访问此视图，因此必须添加一些权限。一种简单的方法是重写内置的 @user_passes_test 装饰器：
  @user_passes_test （lambda u：u.is_staff，login_url = reverse_lazy（'login'））
 def delete_user（请求，用户名）：
＃... 
  
 
I have a simple website where users can register in order to have access to private content and to receive a newsletter. I have used django-registration for user registration and authentication, and  used some HTML templates from here. 

The whole system is working (login, logout, password recovery, etc.) but I realized that user cannot delete their account from the website. Is there a plugin designed for this, or how to extend the registration classes to do that? By deleting, I'd prefer a real suppression, not just making the user inactive.  
解决方案
You can do something like this:
def delete_user(request, username):
    context = {}
    
    try:
        u = User.objects.get(username=username)
        u.delete()
        context['msg'] = 'The user is deleted.'       
    except User.DoesNotExist: 
        context['msg'] = 'User does not exist.'
    except Exception as e: 
        context['msg'] = e.message

    return render(request, 'template.html', context=context) 
And have a url pattern like:
url(r'^delete/(?P<username>[\w|\W.-]+)/$', views.delete_user, name='delete-user')
This will do the work. It will delete a user by given username.
But, as the docs say:

is_active
Boolean. Designates whether this user account should be considered active. We recommend that you set this flag to False instead of deleting accounts; that way, if your applications have any foreign keys to users, the foreign keys won’t break.
It is a better approach to set the user as inactive instead of deleting it totally from the database, because the foreign keys will break.
So you can simply do:
def delete_user(request, username):
    context = {}

    try:
        user = User.object.get(username=username)
        user.is_active = False
        user.save()
        context['msg'] = 'Profile successfully disabled.'
    except User.DoesNotExist:
        # ...
    except Exception as e:
        # ...
    
    # ...
And as now everyone can access this view, you must add some permissions. A straightforward approach will be to override the built-in @user_passes_test decorator:
@user_passes_test(lambda u: u.is_staff, login_url=reverse_lazy('login'))
def delete_user(request, username):
    # ...
