尝试获取用户名时的问题

Question

当我运行这个时：

from django.shortcuts import render  
from django.http import HttpResponse  
from django.contrib.auth.models import User
from django.contrib.auth import authenticate, login as auth_login
  
def login(request):
    if request.user.is_authenticated():
        username = request.user.username
    else:
        username = None
    return render (request, 'login_success.html', {'username': username})

我收到此错误：

TypeError at /login/success/
'bool' object is not callable

这是我的 html：

{% include 'base.html' %}

<text align="center">Sup {{ username }}, you're logged in!</text>

该错误是什么意思，我该如何解决？

is_authenticated 是一个属性，你只需要去掉括号
