How do I check whether this user is anonymous or actually a user on my system?
提问by TIMEX
def index(request):

在 Django 中，我怎么知道它是否是真正的用户？我试过：
if the_user:but "AnonymousUser" is there even if no one logs in. So, it always returns true and this doesn't work.
if the_user:但是即使没有人登录，“AnonymousUser”也在那里。因此，它总是返回 true 并且这不起作用。

if user.is_anonymous():

is by testing to see what the id of the user object is:
是通过测试来查看用户对象的 id 是什么：
if user.id == None:
# user is anon user
else:
# user is a real user
see https://docs.djangoproject.com/en/dev/ref/contrib/auth/#anonymous-users

from django.contrib.auth.decorators import login_required
@login_required
def my_view(request):

I had a similar issue except this was on a page that the login_redirect_url was sent to. I had to put in the template:
我有一个类似的问题，除了这是在 login_redirect_url 被发送到的页面上。我不得不放入模板：
{% if user.is_authenticated %}
Welcome Back, {{ username }}
{% endif %}
