前言
来看一段代码
def current_datetime(request): now = datetime.datetime.now() html = "<html><body>It is now %s.</body></html>" % now return HttpResponse(html)
直接把HTML页面嵌套在视图函数里返回给浏览器并不是一个好主意；
原因：
1、对页面设计进行的任何改变都必须对 Python 代码进行相应的修改，牵一发而动全身；
2、Python 代码编写和 HTML 设计是两项不同的工作，前端开发和后端开发无非 并行；
基于这些原因，将HTML页面的设计和后端逻辑设计分离，会更简洁、容易维护开发我们的WEB应用。 我们可以使用 Django的 模板系统 (Template System)来实现这种模式，这就是本章要具体讨论的问题。
模板是什么？
Django自带的模板语言= HTML代码＋逻辑控制代码，注意 模板 ！= HTML，模块 =HTML代码＋逻辑控制代码（特殊标记）；
模板作用？
在server端 把后端的变量 嵌入到HTML中渲染后，返回给浏览器来达到前后端代码分离，页面动态显示的目的；
一、Django模板语言应用：
Django模板语言的语法主要分为2种： {{变量}} 和 {% Tag %} ，{{变量 }}主要用于和视图变量做替换，{% tag %}主要用于做逻辑判断和实现某些功能，正因有了数据+逻辑才构成了模板语言；
1.1、使用双大括号引用视图中的变量
语法：{{ 变量}} ，列表取值：{{列表}}. 索引， 字典取值：{{字典}}.键
<td>{{ forloop.counter }}</td> <td>{{ book.title }}</td> <td>{{ book.price }}</td> <td>{{ book.date}}</td> <td>{{ book.publish}}</td> <td>{{ book.author }}</td>
** {{ forloop.counter }} 渲染循环的次数
View Code1.2:内置变量过滤器的使用
如果引用得视图变量，不能直接渲染使用，可以借助fifter进行数据的二次处理，就像Python中的内置函数；
语法：{{ 变量|fifter:参数 }}
过滤器列表：
- add：给变量加上相应的值、
- addslashes :单引号加上转义号，一般用于输出到javascript中
- capfirst ：第一个字母大写
- {{ "123spam456spam789"|cut:"spam" }}查找删除指定的字符串
- {{ l1|slice:":2" }} 列表切边
- {{ t|date:'Y-m-d' }} 转换特定时间格式
- {{ s|default:'空空如也' }} 值不存在，使用指定值
- {{ info|truncatechars:18 }} 渲染指定长度的字符
- {{ info1|truncatewords:9 }}渲染指定长度的单词
- {{ a|safe }} 声明安全可以渲染
- {% if forloop.counter|divisibleby:2 %} 整除
实例
视图
from django.shortcuts import render import datetime def fifters(request): i=10 w="A'B'C'D'E" f='china' t=datetime.datetime.now() s='' l1=[98890,765,9870,7654] info='嘲笑我吧你们这些毫无眼光的人，我必将引来雷霆万钧的力量，摧古拉朽得战胜一切敌人！' info1='You laugh at me without the vision of people, and I will lead to an irresistible force power, corruption must defeat all enemies destroy gura!' li=['a','b','c','d','e','f','g'] str1='{{hello world}}' a='<a href="黄色网址">点击我</a>' fhjsaldfhjsdfhlasdfhljsdal='hellow world' return render(request,'modals.html',locals())
模板
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>模板渲染</title> </head> <body> <p>{{ i|add:200 }}</p> <p>{{ w|addslashes}}</p> <p>{{ f|capfirst }}</p> <p>{{ "123spam456spam789"|cut:"spam" }}</p> <p>{{ t|date:'Y-m-d' }}</p> <p>{{ l1|slice:":2" }}</p> <p>{{ s|default:'空空如也' }}</p> <p>{{ info|truncatechars:18 }}</p> <p>{{ info1|truncatewords:9 }}</p> <p> {% csrf_token%} {% for foo in li %} <li>{{ forloop.counter0 }}----->{{ foo }}</li> {% empty %} <li>没有符合的对象</li> {% endfor %} </p> <p> {% verbatim %} {{ str1 }} {% endverbatim %} </p> <p> {% with total=fhjsaldfhjsdfhlasdfhljsdal %} {{ total }} {% endwith %} </p> <p>{{ a|safe }}</p> </body> </html> 更多参考：豆瓣：https://www.douban.com/note/145065606/，袁浩：http://www.cnblogs.com/sss4/p/7071183.html
2.1、内置标签（tag）的使用
如果引用到了视图中的变量，还不足以渲染出一个完美的页面，那就要借助tag标签，做逻辑控制和功能完善了；
语法格式: {% tags %}
{% for %} {% endfor %} for循环
{% for row in list %} </tr> <td>{{ row.id }}</td> <td>{{ row.name }}</td> <td>{{ row.title }}</td> <td><a href="#" onclick="show_modal(this)">添加</a></td> <td id="del_s"><a href="#" onclick="modal_del(this)">删除</a> </td> <td><a href="#"onclick="modal_edit(this)">编辑</a></td> </tr> {% endfor %}
{% if %}{% endfor %} if判断
<select name="class_id" id=""> {% for row in dict %} {% if row.id == name1.class_id %} <option selected value="{{ row.id }}">{{ row.title}}</option> {%else%} <option value="{{ row.id }}">{{ row.title}}</option> {%endif%} {% endfor %} </select>
{% if row.id in cids%} in 成员关系判断
<p>任教课程： <select name="class_id" multiple size="5"> {% for row in clas %} {% if row.id in cids%} <option selected value={{ row.id}}>{{ row.title}}</option> {%else%} <option value={{ row.id}}>{{ row.title}}</option> {% endif %} {% endfor %} </select> </p>
{% empty %} 没有渲染到数据，提示。
{% for foo in li %} <li>{{ forloop.counter0 }}----->{{ foo }}</li> {% empty %} <li>没有符合的对象</li> {% endfor %}
{% verbatim %}{% endverbatim %} 禁止渲染
视图
str1='{{hello world}}'
模板
{% verbatim %}
{{ str1 }}
{% endverbatim %}
{% csrf_token %}
用于生成csrf_token的标签，用于防治跨站攻击验证（csrf）。 其实，这里是会生成一个input标签，和其他表单标签一起提交给后台的。
{% url %} 引用路由分配系统配置的 path 别名
<form action="{% url "bieming"%}" > <input type="text"> <input type="submit"value="提交"> {%csrf_token%} </form>
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <p>{{args}}</p> <p>{% url "zhangge" i i1%}</p> </body> </html>
{% with %} {% endwith %} 用更简单的变量名 替代视图复杂的变量名
fhjsaldfhjsdfhlasdfhljsdal='hellow world' 把后端复杂的变量名，转换得更加简单； <p> {% with total=fhjsaldfhjsdfhlasdfhljsdal %} {{ total }} {% endwith %} </p>
在标签里添加reversed来反序循环列表
{% for log in logs reversed %} {% if forloop.counter|divisibleby:2 %} <dl> <dd class="pos-right clearfix"> <div class="circ"></div> <!--圆圈--> <div class="time"><p>{{ log.update_time }}</p></div> <!--时间--> <div class="events"> <div class="events-header"> <p>{{ log.details }}</p> </div> <div class="events-footer"> <span>{{ log.verbose_content }}</span> </div> </div> <!--内容 --> </dd> </dl> <!--通过设置class="pos-方向clearfix" --> {% else %}
二、自定义fifter和simp-tag
模板语言自带的tag和过滤器，在某些情况下还不能满足我的功能需求，例如无法实现递归显示需求等，可以自定义fifter和tag；就像Python内置函数和自定义函数关系；
1、在app中创建 templatetags目录或Python包（注意 该报的名称必须为 templatetags）
2、templatetags文件夹下随便创建个Python文件,自定义函数；
from django import template register=template.Library() @register.filter #自定义fifter 就使用 fifter装饰器 def mutil(x,y): return x*y @register.simple_tag #自定义tag 就使用 simlep_tag装饰器 def mutil2(x,y,z): return x*y*z
3、注册到setings.py文件里
4、加载到模板里
{% load mytag %}
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>模板渲染</title>
</head>
5、引用到模板
a.
{{ i| mutil:10 }} #自定义fifter的使用
{% mutil2 78 90 20 %} #自定义tag的使用
b.注意引用到 母版继承的模板
{% extends "arya/layout.html" %} {% load Count %} #------------------》注意在子模板的 extends之下。
{% block content %}
6、自定义fifter和simp-tag 区别
1、simple-fifter
优点：支持iif else 条件判断
{% if i|mutil:20 > 100 %} <p>大于</p> {% else %} }} <p>小于</p> {% endif %}
缺点：simple-fifter类型的函数只支持2两个参数
2、simple-tag
优点：simple-fifter类型 无限制传参
{% mutil2 78 90 20 %} #参数无限制
缺点：不支持iif else 条件判断
三、母版继承
在整个网站中，如何减少共用页面区域（比如站点导航）所引起的重复和冗余代码？Django 解决此类问题的首选方法是使用一种优雅的策略—— 模板继承 。
本质上来说，模板继承就是先构造一个基础框架模板，而后在其子模板中对它所包含站点公用部分和定义块进行重载。
子模板 继承、重写 母板的block内容；
1、母版定义block块：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>后台布局</title> <style> .header{ width: 100%; height: 48px; background-color: blue; position: fixed; top: 0px; left: 0px; } .left{ width: 200px; background-color: mediumvioletred; position: fixed; top: 48px; left: 0px; bottom: 0px; } {# 要想设置长度沾满屏，就设置position: fixed ，bottom: 0px;#} .right{ background-color: pink; position: fixed; top: 48px; left: 200px; bottom: 0px; right: 0px; overflow: scroll; } .title li{ margin-top: 80px; } </style> </head> <body> <div class="content"> <div class="header"></div> <div class="left"> <ul class="title" style="list-style-type:none"> <li><a href="/menu1/">菜单1</a></li> <li><a href="/menu2/">菜单2</a></li> <li><a href="/menu3/">菜单3</a></li> </ul> </div> <div class="right"> {% block con %} {% endblock %} </div> </div> </body> </html>
2、子版继承母版中 block
{% extends 'base.html' %} {% block con %} <h1>菜单{{ id }}</h1> <h1>菜单{{ id }}</h1> <h1>菜单{{ id }}</h1> <h1>菜单{{ id }}</h1> <h1>菜单{{ id }}</h1> <h1>菜单{{ id }}</h1> {% endblock %}
扩展：
模板的CSS样式和JS代码不完全是子版想要继承的怎么办？
模板的定义的block越多越好，这样就可以多处重写母版样式；
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>后台布局</title> <style> .header{ width: 100%; height: 48px; background-color: blue; position: fixed; top: 0px; left: 0px; } .left{ width: 200px; background-color: mediumvioletred; position: fixed; top: 48px; left: 0px; bottom: 0px; } {# 要想设置长度沾满屏，就设置position: fixed ，bottom: 0px;#} .right{ background-color: pink; position: fixed; top: 48px; left: 200px; bottom: 0px; right: 0px; overflow: scroll; } .title li{ margin-top: 80px; } </style> {% block css1 %} {% endblock %} </head> <body> <div class="content"> <div class="header"></div> <div class="left"> <ul class="title" style="list-style-type:none"> <li><a href="/menu1/">菜单1</a></li> <li><a href="/menu2/">菜单2</a></li> <li><a href="/menu3/">菜单3</a></li> </ul> </div> <div class="right"> {% block con %} {# #这样子版就可以重写母版的CSS样式了，重载JavaScript亦是如此！#} {% endblock %} </div> </div> </body> </html>
例如：
1.先创建一个base.htm 用来引入站点都要用到的 jQuery、bootstrap；
2.head设置 outside_css、outside_js块让其他模板引入外部文件；
3.body设置content块让其他模板嵌套内容；
4.button the body and the html中间设置 inside块让用户扩展自己的JavaScript代码；
这么做的好处： 可以减少代码冗余、提升代码重用性、减少外部JavaScript文件的反复引入耗时，也可以分门别类的管理外部引入文件，避免引入外部文件过多时。容易出现的引入新文件不生效、生效了页面显示错误......这些头令人头疼的问题；

3、include 组件嵌套
3.1.把多个模板共用的css或者JavaScript代码集成到1个组件，变成公共组件，让其他模板通过{% include xxx %} 直接引入进来使用即可；（提高代码重用性）
{% load simple-fifter %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>主页</title> </head> <body> <h2>simple-fifter</h2> {% for iteam in userinfo %} {{ iteam|my_upper:'666' }} {% endfor %} <h2>simple-tag</h2> {%my_join userinfo '666' '888' %} {% include 'public.html' %} {% include 'public.html' %} {% include 'public.html' %} {% include 'public.html' %} {% include 'public.html' %} {% include 'public.html' %} {% include 'public.html' %} {% include 'public.html' %} </body> </html>
3.2.多层嵌套的include组件
在inculde组件里还可以继续嵌套include组件，这样可以使你的模板代码变得更加简洁、灵活、易于扩展。
