尝试使用django模板处理一个简单的导航菜单时，我在设置特定菜单项上的当前类时遇到问题。以下是我的基本模板：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
 <title>{% block title %}{% endblock %}</title> 
 <meta http-equiv="content-type" content="text/html;charset=utf-8" />
 <link rel="stylesheet" type="text/css" href="/media/css/base.css" />
 <link rel="stylesheet" type="text/css" href="/media/css/login.css" />
 <link rel="stylesheet" href="/site_media/css/style.css" type="text/css" />
 <!--[if lte IE 7]><link rel="stylesheet" type="text/css" href="/media/css/ie.css" /><![endif]-->
</head>
 <body class="{% block bodyclass %}{% endblock %}">
 {% block content %}{% endblock %} 
 {% block footer %}{% endblock %}
</body> 
</html>

{% defmenu "menu1" %}

{% active %}<span class='active'>{{text}}</span>{% endactive %}
{% inactive %}<a href='{{url}}'>{{text}}</a>{% endinactive %}

{% opt "opt1" "/opt1/" %}Go to opt1{% endopt %}
{% opt "opt2" "/opt2/" %}Go to opt2{% endopt %}
{% opt "opt3" "/opt3/" %}Go to opt3{% endopt %}

{% enddefmenu %}


{%block title%}{%endblock%}
{%block content%}{%endblock%}
{%block-footer%}{%endblock%}

然后我有一个nav.html：

 <ul id="top">
   <li><a class="{% block home %}{% endblock %}" href="/">Home</a></li>
   <li><a class="{% block myaccount %}{% endblock %}" href="/profile/">My Account</a></li>
   {% if perms.staffing.add_staffrequest %}
    <li><a class="{% block createsr %}{% endblock %}" 
     href="/create/staffrequest/">Staff Request</a></li>
   {% endif %}
  </ul>




{%if perms.staffing.add_staffrequest%}

{%endif%}

现在在my home.html中，我似乎无法显示当前的类：

{% extends "base.html" %}
{% block title %}Home Portal{% endblock %}
{% block content %}

<div id="content">
 {% include "nav.html" %}
    {% block home %}current{% endblock %} 
 <div id="intro">
  <p>Hello, {{ user.first_name }}.</p>
  <p>Please create a Staff Request here by filling out the form
  below.</p>
 </div> <!-- end intro -->
 <div id="logout">
  <a href="/accounts/logout" alt="Sign Off" title="Sign Off">Sign Off</a>
 </div>
</div> <!-- end content -->

{% endblock %}

{%extends“base.html”%}
{%block title%}主门户{%endblock%}
{%block content%}
{%include“nav.html”%}
{%block home%}当前{%endblock%}
你好，{{user.first_name}}
请通过填写表格在此处创建员工申请
下面
{%endblock%}

“current”类没有显示在相应元素的导航中，因此我可以根据用户所在的页面为其设置可视上下文。

我认为您无法替换包含模板中的块。我的建议是，您需要重新考虑模板的逻辑。我想应该是这样的：

base.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
 <title>{% block title %}{% endblock %}</title> 
 <meta http-equiv="content-type" content="text/html;charset=utf-8" />
  <link rel="stylesheet" type="text/css" href="/media/css/base.css" />
  <link rel="stylesheet" type="text/css" href="/media/css/login.css" />
  <link rel="stylesheet" href="/site_media/css/style.css" type="text/css" />
  <!--[if lte IE 7]><link rel="stylesheet" type="text/css" href="/media/css/ie.css" /><![endif]-->
 </head>
  <body class="{% block bodyclass %}{% endblock %}">
  {% block content %}

     <div id="content">

         {% block navigation %}
             <ul id="top">
                <li><a class="{% block home %}{% endblock %}" href="/">Home</a></li>
                <li><a class="{% block myaccount %}{% endblock %}" href="/profile/">My Account</a></li>
                {% if perms.staffing.add_staffrequest %}
                 <li><a class="{% block createsr %}{% endblock %}" 
                  href="/create/staffrequest/">Staff Request</a></li>
                {% endif %}
             </ul>
         {% endblock %}

         {% block real_content %}
         <div id="intro">
             <p>Hello, {{ user.first_name }}.</p>
             <p>Please create a Staff Request here by filling out the form below.</p>
          </div> <!-- end intro -->

          <div id="logout">
           <a href="/accounts/logout" alt="Sign Off" title="Sign Off">Sign Off</a>
          </div>
          {% endblock %}

     </div> <!-- end content -->


  {% endblock %} 
  {% block footer %}{% endblock %}
 </body> 
 </html>


{%block title%}{%endblock%}
{%block content%}
{%block-navigation%}



{%if perms.staffing.add_staffrequest%}

{%endif%}

{%endblock%}
{%block real_content%}
你好，{{user.first_name}}
请填写下表，在此处创建员工申请
{%endblock%}
{%endblock%}
{%block-footer%}{%endblock%}

你的home.html应该是

{% extends "base.html" %}
{% block title %}Home Portal{% endblock %}

{% block home %}current{% endblock %}


{% block real_content %}

<div id="content">

 <div id="intro">
  <p>Hello, {{ user.first_name }}.</p>
  <p>Please create a Staff Request here by filling out the form
  below.</p>
 </div> <!-- end intro -->
 <div id="logout">
  <a href="/accounts/logout" alt="Sign Off" title="Sign Off">Sign Off</a>
 </div>
</div> <!-- end content -->

{% endblock %}

{%extends“base.html”%}
{%block title%}主门户{%endblock%}
{%block home%}当前{%endblock%}
{%block real_content%}
你好，{{user.first_name}}
请通过填写表格在此处创建员工申请
下面
{%endblock%}

另一种处理方法是只使用CSS文件中的body.class

nav.html

 <ul id="top">
   <li><a class="home" href="/">Home</a></li>
   <li><a class="myaccount" href="/profile/">My Account</a></li>
   {% if perms.staffing.add_staffrequest %}
    <li><a class="createsr" 
     href="/create/staffrequest/">Staff Request</a></li>
   {% endif %}
  </ul>

{% block bodyclass %}home{% endblock %}

您的css文件

body.home li.home { font-weight: bold; color: blue; }
body.myaccount li.myaccount { font-weight: bold; color: blue; }
body.createsr li.createsr { font-weight: bold; color: blue; }

它会干涸，但有时比处理一些疯狂的阻塞模板更简单。

您可以使用“干涸”菜单自定义模板标记解决复制问题。它还解决了主动/非主动菜单类的问题。请看下面的描述。源代码：

干式菜单模板标签的说明

这是用于创建干式菜单的自定义模板标记的说明。它解决了站点模板中标记重复的问题。菜单始终有一个活动选项和一个或多个非活动选项

如何使用

在父模板中定义菜单的结构：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
 <title>{% block title %}{% endblock %}</title> 
 <meta http-equiv="content-type" content="text/html;charset=utf-8" />
 <link rel="stylesheet" type="text/css" href="/media/css/base.css" />
 <link rel="stylesheet" type="text/css" href="/media/css/login.css" />
 <link rel="stylesheet" href="/site_media/css/style.css" type="text/css" />
 <!--[if lte IE 7]><link rel="stylesheet" type="text/css" href="/media/css/ie.css" /><![endif]-->
</head>
 <body class="{% block bodyclass %}{% endblock %}">
 {% block content %}{% endblock %} 
 {% block footer %}{% endblock %}
</body> 
</html>

{% defmenu "menu1" %}

{% active %}<span class='active'>{{text}}</span>{% endactive %}
{% inactive %}<a href='{{url}}'>{{text}}</a>{% endinactive %}

{% opt "opt1" "/opt1/" %}Go to opt1{% endopt %}
{% opt "opt2" "/opt2/" %}Go to opt2{% endopt %}
{% opt "opt3" "/opt3/" %}Go to opt3{% endopt %}

{% enddefmenu %}

此处：“menu1”是由“defmenu”标记定义的菜单名称，“opt1”是选中选项

应用“菜单”的结果是下一个：

<span class='active'> Go to opt1</span> <a href='"/opt2/"'>Go to opt2</a> <a href='"/opt3/"'>Go to opt3</a>

转到opt1

我已更改了答案。希望能有帮助。
