Django 1.5 - django-ldap-auth
试图弄清楚如何正确使用 request_to_context 因为它只适用于 login.html 页面本身。（user.is_authenticated 等）。
用户登录后，它会将用户转发到 /reboot。从那里我想使用 {{ user.is_authenticated }} / {{ user.username }}，但没有显示（真或假）。它只是空白。
在 login.html 页面本身上，它们可以正常工作。如果我渲染到 reboot/index.html 它不会渲染我拥有索引的代码。我假设我可以在用户通过身份验证后调用这些命令。希望我只是错过了这个难题的一小部分。
我已经包含了所有必要的代码。让我知道您是否需要其他东西。
这是我的布局。

我感谢您的所有帮助。我已经在这个问题上停留了几天，一直无法弄清楚。
