Django：根据用户是否创建了用户个人资料显示不同的导航栏选项？

标签： django python-3.x

我有一个问题，即如果用户未创建用户个人资料，如何显示导航栏的不同选项。我尝试了许多选项，包括在base.html上使用{％ifprofiles_list％}以及{％ifequal user userprofiles.objects.all％}以及在templatetags上创建一个简单标签，但是它似乎不起作用。

我也尝试过更改视图，但是由于我是编码的新手，所以我更喜欢使用“ base.html”。但是，任何建议都会受到欢迎。我希望选项以某种方式显示，如果用户尚未创建个人资料，则只会显示搜索，消息，关于我们以及创建新个人资料的选项。并且，如果他们已经创建了配置文件，则创建新的配置文件将被编辑配置文件替换，并且还将显示“删除配置文件”和“查看配置文件”的其他选项。

我的代码如下：

   base.html

<div class="container">
  <nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="{% url 'home:index' %}">  <img src="{% static "images/rainbow.jpg" %}" width="100" height="100" alt=""></a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarNav">
      <ul class="navbar-nav">
        {% if user.is_authenticated %}
        <li class="nav-item active">
          <a class="nav-link" href="{% url 'home:about' %}">About Us <span class="sr-only">(current)</span></a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="{% url 'userprofile:editprofile' user.pk %}">Edit Profile</a>

          <a class="nav-link" href="#">Messages</a>
        </li>
        <li class="nav-item">
            <!-- login/logout dont need namespace app -->
          <a class="nav-link" href="{% url 'logout' %}">Logout</a>

            {% else %}

        <li>
          {% endif %}
      </ul>
    </div>

User和UserProfiles之间的关系是一对一的，因此没有all（无论如何，检查列表是否等于用户是没有意义的）。您应该只检查user.userprofiles。

{% if user.userprofiles %}
  ... show edit links ...
{% else %}
  ... show create links ...
{% endif %}

注意，Django风格是对模型类使用单数名称：它应该是UserProfile。无论如何，这更有意义，因为这样的关系就是user.userprofile。
