我在我的 Django 元素中创建了一个 base.html，我从中继承了其余的 html 页面。在我的 base.html 中，我创建了一个导航栏，如果用户已登录，它会显示主页、关于、联系和 [我的个人资料和注销]，否则它会显示 [注册]。 问题是当我在我的主页登录时，我确实看到按钮 [我的个人资料]，但是当我访问联系人或关于页面时，[我的个人资料] 导航栏按钮丢失但 [注销] 工作正常。
这是我的 base.html

最佳答案
你的我的个人资料取决于一个名为 things 的上下文变量，它必须出现在你的主页中，但没有别的。我想你每个用户只有一个东西，所以你要么只使用那个，要么拿第一个
{% for thing in things %}
{% if user == thing.user %}
<li><a href="{% url 'thing_detail' slug=thing.slug %}">My Profile</a></li>
{% endif %}
{% endfor %}
应该是以下之一:
事物与用户之间存在多对一关系
<li><a href="{% url 'thing_detail' slug=user.thing_set.first.slug %}">My Profile</a></li>事物与用户是一对一的关系
<li><a href="{% url 'thing_detail' slug=user.thing.slug %}">My Profile</a></li>
