如何获得认证的用户列表？ [英] How to get the list of the authenticated users?

问题描述

我想显示身份验证的用户列表。

I would like to display the list of the authenticated users.

在文档：<一href=\"http://docs.djangoproject.com/en/dev/topics/auth/\">http://docs.djangoproject.com/en/dev/topics/auth/

类models.User结果
  is_authenticated（）¶结果
      总是返回true。这是一种方式告诉用户是否被认证。 ...

class models.User
is_authenticated()¶
Always returns True. This is a way to tell if the user has been authenticated. ...

您可以知道在模板上侧是在电流用户进行身份验证或不：

You can know on the template side is the current User is authenticated or not:

{％如果user.is_authenticated％}
         {％endif％}次

{% if user.is_authenticated %} {% endif %}

但我没有找到得到验证的用户列表的方式。

But I didn't found the way the get the list of the authenticated users.

任何想法？

推荐答案

与RZ的答案一起去，你可以查询未过期的会话会话模式，然后打开会话数据到用户。一旦你得到了，你可以把它变成一个模板标签，它可以使任何给定的页面的列表中。

Going along with rz's answer, you could query the Session model for non-expired sessions, then turn the session data into users. Once you've got that you could turn it into a template tag which could render the list on any given page.

（这是所有未测试，但希望将接近工作）。

(This is all untested, but hopefully will be close to working).

提取所有已登录的用户...

Fetch all the logged in users...

from django.contrib.auth.models import User
from django.contrib.sessions.models import Session
from django.utils import timezone

def get_all_logged_in_users():
    # Query all non-expired sessions
    # use timezone.now() instead of datetime.now() in latest versions of Django
    sessions = Session.objects.filter(expire_date__gte=timezone.now())
    uid_list = []

    # Build a list of user ids from that query
    for session in sessions:
        data = session.get_decoded()
        uid_list.append(data.get('_auth_user_id', None))

    # Query all logged in users based on id list
    return User.objects.filter(id__in=uid_list)

利用这一点，你可以做一个简单的包含模板标签...

Using this, you can make a simple inclusion template tag...

from django import template
from wherever import get_all_logged_in_users
register = template.Library()

@register.inclusion_tag('templatetags/logged_in_user_list.html')
def render_logged_in_user_list():
    return { 'users': get_all_logged_in_users() }

logged_in_user_list.html

{% if users %}
<ul class="user-list">
    {% for user in users %}
    <li>{{ user }}</li>
    {% endfor %}
</ul>
{% endif %}

然后在你的主页，你喜欢，你可以简单地使用它...

Then in your main page you can simply use it where you like...

{% load your_library_name %}
{% render_logged_in_user_list %}

修改

对于那些在谈论2周持续性的问题，我假设，任何人想要有一个活跃用户式的上市将被利用的<一个href=\"http://docs.djangoproject.com/en/dev/topics/http/sessions/#browser-length-sessions-vs-persistent-sessions\"><$c$c>SESSION_EXPIRE_AT_BROWSER_CLOSE设置，虽然我承认这一点并不总是如此。

For those talking about the 2-week persistent issue, I'm assuming that anyone wanting to have an "active users" type of listing will be making use of the SESSION_EXPIRE_AT_BROWSER_CLOSE setting, though I recognize this isn't always the case.
