在本文中，我将介绍在Django应用程序开发中设计Django模板的方法。目的是保持Django应用程序的UI部分井井有条，并避免重复编码。Django在模板引擎中提供了各种机制来帮助我们实现这一目标。在本教程中，我将说明如何使用Django内置模板标记块，扩展和包含来使模板易于维护。
准备工作：
1、Python 3.6
2、Django 2.2
3、AdminLTE 3.0.5
我们目标是将模板文件有效组织起来，避免重复的代码引用，我们分四个步骤来实现。
步骤1/4：base.html
将模板分为多个部分，我们知道除了菜单和内容外，其他所有内容都是可重复的。 我们将制作一个基本模板来容纳那些常见的部分，如图：
在项目文件夹中创建一个文件夹模板。 在其中创建一个base.html。 将所有常见的片段添加到其中。只需复制并粘贴以下内容，仅是load.html和index.html共享的一部分代码。
{% load static %}

步骤2/4：删除冗余的通用代码
由于我们在上一步中创建了base.html，因此不再需要将通用代码保留在Landing.html和home.html中。 我们应该得到如下结果。

步骤3/4：继承base.html
为了将base.html用作每个页面的基础模板，我们需要通过在模板的开头使用{％extended‘base.html’％}来声明base.html为“父”模板。 最重要的是，不要忘记content_wrapper块。 将全部内容包装到该块中。 我们应该得到如下结果。
landing.html:
{% extends 'base.html' %}
{% load static %}
{% block content_wrapper %}
<div class="content-wrapper">
. . .
</div>
{% endblock %}
在index.html:
{% extends 'base.html' %}
{% load static %}
{% block content_wrapper %}
<div class="content-wrapper">
. . .
</div>
{% endblock %}
步骤4/4：将常见的内容单独存放
现在我们可能会意识到，两个模板中都存在相同的巨型形式。几乎一半的代码是它。由于此表单已在两个模板中重复使用，因此我们将其维护在一个可以包含任何模板的地方。
在模板文件夹中创建一个文件夹advanced_forms。 在advanced_forms文件夹中，创建如下的general_elements_form.html，代码如下：
<form role="form">
<div class="row">
<div class="col-sm-6">
<!-- text input -->
<div class="form-group">
<label>Text</label>
<input type="text" class="form-control" placeholder="Enter ...">
</div>
</div>
<div class="col-sm-6">
<div class="form-group">
<label>Text Disabled</label>
<input type="text" class="form-control" placeholder="Enter ..." disabled>
</div>
</div>
</div>
<div class="row">
<div class="col-sm-6">

<div class="form-group">

</div>
</div>

</div>
</div>

<div class="form-group">
<label class="col-form-label" for="inputWarning"><i class="far fa-bell"></i> Input with

删除Landing.html和index.html中的多余表单代码。使用{％ include ‘advanced_forms/general_elements_form.html’ ％}包含表单。 设置好之后，这就是最终结果。
index.html:

{% load static %}
{% block content_wrapper %}
