Django user.is_authenticated在某些地方工作，而不是其他地方 [英] Django user.is_authenticated works some places, not others

问题描述

在我的模板中，我有以下内容：

In my template, I have the following:

        <ul class="tabbed" id="network-tabs">
            {% if user.is_authenticated %}
            <li><a href="{% url acct-my-profile %}">My Account</a></li>
            <li><a href="{% url acct-logout %}">Log Out</a></li>
            {% else %}
            <li><a href="{% url acct-login %}">Log in</a></li>
            <li><a href="{% url acct-register %}">Register</a></li>
            {% endif %}
        </ul>

似乎工作正常，除非创建的页面有@login_required装饰器，在这种情况下页面工作正常，但导航显示为用户未登录，即使他们是。

It seems to work fine, unless the page been created has a @login_required decorator, in which case the page works fine but the navigation appears as if the user is not logged in, even when they are.

推荐答案

你应该检查你的查看功能以查看用户变量来自哪里。除非您从视图中将用户专门传递到上下文中，否则这是您的问题。

You should check your view function to see where the user variable is coming from. Unless you're specifically passing user into the context from the view, that's your problem.

您 do 可以访问 request.user ，并且将始终在从具有 @的视图呈现的模板中返回true login_required 装饰器。

You do have access to request.user, though, and that will always return true in a template rendered from a view that has the @login_required decorator.

我可以告诉你一些装饰器没有错的原因，但是在用户和 AnonymousUser （位于 django.contrib.auth.models ） is_authenticated 方法对于用户严格返回true，对于 AnonymousUser 。装饰者不会也不能改变。这意味着你的模板实际上并没有获得用户对象，您正在检查用户。

The reason I can tell you for certain that there's nothing wrong with the decorator, though, is that in the code for User and AnonymousUser (located in django.contrib.auth.models) the is_authenticated method strictly returns true for User and false for AnonymousUser. The decorator does not and cannot change that. And what that means is that your template isn't actually getting a User object where you're checking user.
