导航栏无法正常工作 - Django

时间:2016-03-11 09:46:16

标签: python html css django web-applications

我在我的Django项目中创建了一个base.html,我继承了其余的html页面。在我的base.html中,我创建了一个导航栏,显示Home,About,Contact和[Myprofile and Logout]如果用户已登录,则显示[Register]。 问题是,当我登录我的主页时,我确实看到了按钮[Myprofile],但是当我访问联系人或关于页面时,[Myprofile]导航栏按钮丢失,但[Logout]工作正常。

这是我的base.html

您的个人资料取决于名为things的上下文变量,该变量必须出现在您的主页中,但不得出现在其中。我想你每个用户只有一件事,所以你要么只需要使用它,要么采取第一个

 {% 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:

  • Thing与用户有多对一的关系

    <li><a href="{% url 'thing_detail' slug=user.thing_set.first.slug %}">My Profile</a></li>
    
  • Thing与用户有一对一的关系

    <li><a href="{% url 'thing_detail' slug=user.thing.slug %}">My Profile</a></li>
