Question

在我的Django项目中，有几个应用程序（app1，app2，app3）。 App1在视图内部有多个视图模型，包括登录和验证登录后，网页返回“主页”，我的base.html有以下命令显示用户名。
这个base.html文件在项目的整个应用程序中共享。

        <ul class="nav navbar-nav pull-right">
            {% if request.user.is_authenticated %}
            <li><a href="/">{{ request.user.username }}</a></li>
            <li><a href="/accounts/logout">Logout</a></li>
            {% else %}
            <li><a href="/accounts/login">Login</a></li>
            {% endif %}
        </ul>

有趣的是，其他app2和app3没有显示用户名，仍然只在navbar-nav上显示“Login”。我想它必须显示"user_name + Logout"。
我以为登录过程没有发生，但似乎这个过程在某种意义上看起来很好，我掩盖了app2和app3，除非他们使用@login_required正确记录。
因此，当我没有登录app1时，app2和3不起作用。但它没有回应{{request.user.username}}。

App2和3有自己的views.py。我不能将所有视图混合在一起，以免使代码变得非常脏。如何解决此问题以在登录后显示正确的用户名和“注销”标志？

以下是app2（民意调查）和app1（注册）的代码

    latest_poll_list = Poll.objects.all().order_by('-pub_date')[:5]
    context = {'latest_poll_list': latest_poll_list}
    return render(request, 'polls/index.html', context)

                                    password=request.POST['password'])
    print 'create', user
    user = auth.authenticate(username=request.POST['username'], password=request.POST['password'])
    print 'authenticated', user
    auth.login(request, user)
    return HttpResponseRedirect(request.POST.get('next', '/') or '/')

在应用程序打印request.user的每个视图中，并检查您是否登录用户名。

而不是{{request.user.username}}而不是{{user.username}}

<ul class="nav navbar-nav pull-right">
            {% if user.is_authenticated %}
            <li><a href="/">{{ user.username }}</a></li>
            <li><a href="/accounts/logout">Logout</a></li>
            {% else %}
            <li><a href="/accounts/login">Login</a></li>
            {% endif %}
        </ul>

现在检查其工作情况

如何让Django中的应用程序知道登录过程已经完成？
