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。

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">
      <!-- textarea -->
      <div class="form-group">
        <label>Textarea</label>
        <textarea class="form-control" rows="3" placeholder="Enter ..."></textarea>
      </div>
    </div>
    <div class="col-sm-6">
      <div class="form-group">
        <label>Textarea Disabled</label>
        <textarea class="form-control" rows="3" placeholder="Enter ..." disabled></textarea>
      </div>
    </div>
  </div>

  <!-- input states -->
  <div class="form-group">

  <div class="row">

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:

{% extends 'base.html' %}
{% load static %}

{% block content_wrapper %}

    <div class="content-header">
