模板层
一 模板语法之变量
在 Django 模板中遍历复杂数据结构的关键是句点字符, 语法:
{{ var_name }}
[[email protected] mysite]# cat app01/urls.py
from django.urls import path,re_path from . import views urlpatterns = [ path("test/",views.test1,name="test1"), path("temp_test/",views.temp_test), ]
[[email protected] mysite]# vim app01/views.py
#模板相关 def temp_test(request): name = "ning" return render(request,"temp_test.html",{"name":name}) #这里定义的必须和html调用的名称一致
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <h3>{{name}}</h3> <script> </script> </body> </html>

二 模板语法之过滤器
过滤器最多只有两个参数
语法:
{{obj|filter__name:param}}
如果一个变量是false或者为空,使用给定的默认值。否则,使用变量的值。例如:
[[email protected] mysite]# vim app01/views.py
def temp_test(request): name = "" list1 = ["john","dachun","joy"] dict1 = {"name":"joy","Age":18} class A: def __init__(self,name,age): self.name = name self.age = age def test(self): return "333666" a1 = A("john",18) a2 = A("dachun",20) a3 = A("joy",22) return render(request,"temp_test.html",{"name":name, "list1":list1, "dict1":dict1, "a1":a1, "a2":a2, "a3":a3 })
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <h3>{{name|default:"nobody"}}</h3> <p>{{list1}}</p> <p>{{list1.1}}</p> <p>{{dict1}}</p> <p>{{dict1.name}}</p> <p>{{dict1.Age}}</p> <p>{{a1}}</p> <p>{{a1.name}}</p> <p>{{a1.name.upper}}</p> <p>{{a2.test}}</p> <script> </script> </body> </html>
访问http://192.168.132.140:8888/app01/temp_test/
2.1 length
返回值的长度。它对字符串和列表都起作用。例如:
{{ value|length }}
如果 value 是 [‘a‘, ‘b‘, ‘c‘, ‘d‘],那么输出是 4。
[[email protected] mysite]# vim app01/views.py
def temp_test(request): name = "darren" list1 = ["john","dachun","joy"] dict1 = {"name":"joy","Age":18} class A: def __init__(self,name,age): self.name = name self.age = age def test(self): return "333666" a1 = A("john",18) a2 = A("dachun",20) a3 = A("joy",22) return render(request,"temp_test.html",{"name":name, "list1":list1, "dict1":dict1, "a1":a1, "a2":a2, "a3":a3 })
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <h3>{{name|default:"nobody"}}</h3> <h3>{{name|length}}</h3> <p>{{list1}}</p> <p>{{list1.1}}</p> <p>{{dict1}}</p> <p>{{dict1.name}}</p> <p>{{dict1.Age}}</p> <p>{{a1}}</p> <p>{{a1.name}}</p> <p>{{a1.name.upper}}</p> <p>{{a2.test}}</p> <script> </script> </body> </html>
访问http://192.168.132.140:8888/app01/temp_test/
2.2 filesizeformat
将值格式化为一个 “人类可读的” 文件尺寸 (例如 ‘13 KB‘, ‘4.1 MB‘, ‘102 bytes‘, 等等)。例如:
{{ value|filesizeformat }}
如果 value 是 123456789,输出将会是 117.7 MB。
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <h3>{{name|default:"nobody"}}</h3> <h3>{{num|filesizeformat}}</h3> <p>{{list1}}</p> <p>{{list1.1}}</p> <p>{{dict1}}</p> <p>{{dict1.name}}</p> <p>{{dict1.Age}}</p> <p>{{a1}}</p> <p>{{a1.name}}</p> <p>{{a1.name.upper}}</p> <p>{{a2.test}}</p> <script> </script> </body> </html>
[[email protected] mysite]# vim app01/views.py
#模板相关 def temp_test(request): name = "darren" num = 12344656787778 list1 = ["john","dachun","joy"] dict1 = {"name":"joy","Age":18} class A: def __init__(self,name,age): self.name = name self.age = age def test(self): return "333666" a1 = A("john",18) a2 = A("dachun",20) a3 = A("joy",22) return render(request,"temp_test.html",{"name":name, "list1":list1, "dict1":dict1, "a1":a1, "a2":a2, "num":num })
访问http://192.168.132.140:8888/app01/temp_test/
2.3 date
如果 value=datetime.datetime.now()
{{ value|date:"Y-m-d" }}
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <h3>{{name|default:"nobody"}}</h3> <h3>{{num|filesizeformat}}</h3> <p>{{now_time|date:"Y-m-d"}}</p> <p>{{list1}}</p> <p>{{list1.1}}</p> <p>{{dict1}}</p> <p>{{dict1.name}}</p> <p>{{dict1.Age}}</p> <p>{{a1}}</p> <p>{{a1.name}}</p> <p>{{a1.name.upper}}</p> <p>{{a2.test}}</p> <script> </script> </body> </html>
[[email protected] mysite]# vim app01/views.py
#模板相关import datetime def temp_test(request): name = "darren" num = 12344656787778 now_time=datetime.datetime.now() list1 = ["john","dachun","joy"] dict1 = {"name":"joy","Age":18} class A: def __init__(self,name,age): self.name = name self.age = age def test(self): return "333666" a1 = A("john",18) a2 = A("dachun",20) a3 = A("joy",22) return render(request,"temp_test.html",{"name":name, "list1":list1, "dict1":dict1, "a1":a1, "a2":a2, "num":num, "now_time":now_time })
访问http://192.168.132.140:8888/app01/temp_test/
2.4 truncatechars
如果字符串字符多于指定的字符数量,那么会被截断。截断的字符串将以可翻译的省略号序列(“...”)结尾。
参数:要截断的字符数,例如:
{{ value|truncatechars:10 }}
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <h3>{{name|default:"nobody"}}</h3> <h3>{{num|filesizeformat}}</h3> <p>{{now_time|date:"Y-m-d"}}</p> <p>{{str1|truncatechars:10}}</p> <p>{{list1}}</p> <p>{{list1.1}}</p> <p>{{dict1}}</p> <p>{{dict1.name}}</p> <p>{{dict1.Age}}</p> <p>{{a1}}</p> <p>{{a1.name}}</p> <p>{{a1.name.upper}}</p> <p>{{a2.test}}</p> <script> </script> </body> </html>
[[email protected] mysite]# vim app01/views.py
#模板相关import datetime def temp_test(request): name = "darren" num = 12344656787778 now_time=datetime.datetime.now() str1="There’s a special providence in the fall of a sparrow" list1 = ["john","dachun","joy"] dict1 = {"name":"joy","Age":18} class A: def __init__(self,name,age): self.name = name self.age = age def test(self): return "333666" a1 = A("john",18) a2 = A("dachun",20) a3 = A("joy",22) return render(request,"temp_test.html",{"name":name, "list1":list1, "dict1":dict1, "a1":a1, "a2":a2, "num":num, "now_time":now_time, "str1":str1 })

2.5 safe
Django的模板中会对HTML标签和JS等语法标签进行自动转义,原因显而易见,这样是为了安全。但是有的时候我们可能不希望这些HTML元素被转义,比如我们做一个内容管理系统,后台添加的文章中是经过修饰的,这些修饰可能是通过一个类似于FCKeditor编辑加注了HTML修饰符的文本,如果自动转义的话显示的就是保护HTML标签的源文件。为了在Django中关闭HTML的自动转义有两种方式,如果是一个单独的变量我们可以通过过滤器“|safe”的方式告诉Django这段代码是安全的不必转义。比如:
[[email protected] mysite]# vim app01/views.py
#模板相关 import datetime def temp_test(request): now_time=datetime.datetime.now() name = "darren" num = 12344656787778 str1="There’s a special providence in the fall of a sparrow" str_a="<a href=\"www.baidu.com\">点击</a>" list1 = ["john","dachun","joy"] dict1 = {"name":"joy","Age":18} class A: def __init__(self,name,age): self.name = name self.age = age def test(self): return "333666" a1 = A("john",18) a2 = A("dachun",20) a3 = A("joy",22) return render(request,"temp_test.html",{"name":name, "list1":list1, "dict1":dict1, "a1":a1, "a2":a2, "num":num, "now_time":now_time, "str1":str1, "str_a":str_a })
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <h3>{{name|default:"nobody"}}</h3> <h3>{{num|filesizeformat}}</h3> <p>{{now_time|date:"Y-m-d"}}</p> <p>{{str1|truncatechars:10}}</p> <p>{{str_a}}</p> <p>{{str_a|safe}}</p> <p>{{list1}}</p> <p>{{list1.1}}</p> <p>{{dict1}}</p> <p>{{dict1.name}}</p> <p>{{dict1.Age}}</p> <p>{{a1}}</p> <p>{{a1.name}}</p> <p>{{a1.name.upper}}</p> <p>{{a2.test}}</p> <script> </script> </body> </html>

三 模板之标签
标签看起来像是这样的: {% tag %}
。标签比变量更加复杂:一些在输出中创建文本,一些通过循环或逻辑来控制流程,一些加载其后的变量将使用到的额外信息到模版中。一些标签需要开始和结束标签 (例如{% tag %} ...
标签 内容 ... {% endtag %})。
3.1 for标签
遍历每一个元素:
[[email protected] mysite]# vim app01/views.py
#模板相关 import datetime def temp_test(request): list1 = ["john","dachun","joy"] dict1 = {"name":"joy","Age":18} class A: def __init__(self,name,age): self.name = name self.age = age def test(self): return "333666" a1 = A("john",18) a2 = A("dachun",20) a3 = A("joy",22) a_list = [a1,a2,a3] return render(request,"temp_test.html",{ "list1":list1, "dict1":dict1, "a_list":a_list })
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <table border="1"> <tr> <th>姓名</th> <th>年龄</th> </tr> {% for a in a_list%} <tr> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {%endfor%} </table> <script> </script> </body> </html>
访问http://192.168.132.140:8888/app01/temp_test/
注:循环序号可以通过{{forloop}}显示
forloop.counter The current iteration of the loop (1-indexed) forloop.counter0 The current iteration of the loop (0-indexed) forloop.revcounter The number of iterations from the end of the loop (1-indexed) forloop.revcounter0 The number of iterations from the end of the loop (0-indexed) forloop.first True if this is the first time through the loop forloop.last True if this is the last time through the loop
示例
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <table border="1"> <tr> <th>序号</th> <th>姓名</th> <th>年龄</th> </tr> {% for a in a_list%} <tr> <td>{{forloop.counter}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {%endfor%} </table> <script> </script> </body> </html>

[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <table border="1"> <tr> <th>序号</th> <th>姓名</th> <th>年龄</th> </tr> {% for a in a_list%} <tr> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {%endfor%} </table> <script> </script> </body> </html>
访问http://192.168.132.140:8888/app01/temp_test/
3.2 for ... empty
for 标签带有一个可选的{% empty %} 从句,以便在给出的组是空的或者没有被找到时,可以有所操作。
{% for person in person_list %} <p>{{ person.name }}</p> {% empty %} <p>sorry,no person here</p> {% endfor %}
3.3 if 标签
{% if %}会对一个变量求值,如果它的值是“True”(存在、不为空、且不是boolean类型的false值),对应的内容块会输出。
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> .green{ background: green } </style> </head> <body> <table border="1"> <tr> <th>序号</th> <th>姓名</th> <th>年龄</th> </tr> {% for a in a_list%} {% if forloop.last %} <tr class="green"> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {% else %} <tr> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> {% endif %} {%endfor%} </table> <script> </script> </body> </html>
访问http://192.168.132.140:8888/app01/temp_test/
[[email protected] mysite]# vim templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> .green{ background: green } .red{ background: red } </style> </head> <body> <table border="1"> <tr> <th>序号</th> <th>姓名</th> <th>年龄</th> </tr> {% for a in a_list%} {% if forloop.last %} <tr class="green"> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {% elif forloop.first %} <tr class="red"> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {%else%} <tr> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {% endif %} {%endfor%} </table> <script> </script> </body> </html>
访问http://192.168.132.140:8888/app01/temp_test/
3.4 with
使用一个简单地名字缓存一个复杂的变量,当你需要使用一个“昂贵的”方法(比如访问数据库)很多次的时候是非常有用的
例如:
{% with total=business.employees.count %} {{ total }} employee{{ total|pluralize }} {% endwith %}
3.5 csrf_token
这个标签用于跨站请求伪造保护,这里再前面的setting.py已经注释掉了
打开
MIDDLEWARE = [ ‘django.middleware.security.SecurityMiddleware‘, ‘django.contrib.sessions.middleware.SessionMiddleware‘, ‘django.middleware.common.CommonMiddleware‘, ‘django.middleware.csrf.CsrfViewMiddleware‘, ‘django.contrib.auth.middleware.AuthenticationMiddleware‘, ‘django.contrib.messages.middleware.MessageMiddleware‘, ‘django.middleware.clickjacking.XFrameOptionsMiddleware‘, ]
[[email protected] mysite]# vi templates/login.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </script> </head> <body> <h3>用户登录</h3> <form action="" method="post"> {%csrf_token%} <p>用户名:<input type="text" name="user"></p> <p>密 码:<input type="password" name="pwd"></p> <input type="submit"> </form> <script> </script> </body> </html>
访问http://192.168.132.140:8888/app01/temp_test/
请求后,会多一个input标签,着个标签是一个随机字符串,用于校验,当login页面娜输入用户名和密码后,会带着返回的随机字符串,进行数据校验,确保值login页面发送的破石头请求
四 自定义标签和过滤器
1、在settings中的INSTALLED_APPS配置当前app,不然django无法找到自定义的simple_tag.这个已经完场
2、在app中创建templatetags模块(模块名只能是templatetags)
[[email protected] mysite]# mkdir app01/templatetags
3、创建任意 .py 文件,如:my_tags.py
[[email protected] mysite]# vim app01/templatetags/my_tags.py
from django import template from django.utils.safestring import mark_safe register = template.Library() #register的名字是固定的,不可改变 @register.filter def my_filter(v1,v2): return v1 * v2 @register.simple_tag def my_tag(v1,v2,v3): return v1 * v2 * v3 @register.simple_tag def my_input(pk,arg): result = "<input type=‘text‘ id=‘%s‘ class=‘%s‘ />" %(pk,arg,) return mark_safe(result)
4 html中导入my_tag文件,并引用
[[email protected] mysite]# vi templates/temp_test.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> .green{ background: green } .red{ background: red } </style> </head> <body> {% load my_tags %} <table border="1"> <tr> <th>序号</th> <th>姓名</th> <th>年龄</th> </tr> {% for a in a_list%} {% if forloop.last %} <tr class="green"> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {% elif forloop.first %} <tr class="red"> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {%else%} <tr> <td>{{forloop.counter}}--{{forloop.first}}++{{forloop.last}}</td> <td>{{a.name}}</td> <td>{{a.age}}</td> </tr> {% endif %} {%endfor%} </table> <hr> <p>{{num|my_filter:2}}</p> <hr> <p>{% my_tag num 5 2 %}</p> <hr> <p>{% my_input 12 ‘green‘ %}</p> <script> </script> </body> </html>
访问http://192.168.132.140:8888/app01/temp_test/
注意:filter可以用在if等语句后,simple_tag不可以
{% if num|filter_multi:30 > 100 %} {{ num|filter_multi:30 }} {% endif %}
五 模板继承 (extend)
Django模版引擎中最强大也是最复杂的部分就是模版继承了。模版继承可以让您创建一个基本的“骨架”模版,它包含您站点中的全部元素,并且可以定义能够被子模版覆盖的 blocks 。
通过从下面这个例子开始,可以容易的理解模版继承:
<!DOCTYPE html> <html lang="en"> <head> <link rel="stylesheet" href="style.css" /> <title>{% block title %}My amazing site{%/span> endblock %}</title> </head> <body> <div id="sidebar"> {% block sidebar %} <ul> <li><a href="/">Home</a></li> <li><a href="/blog/">Blog</a></li> </ul> {% endblock %} </div> <div id="content"> {% block content %}{% endblock %} </div> </body> </html>
这个模版,我们把它叫作 base.html
, 它定义了一个可以用于两列排版页面的简单HTML骨架。“子模版”的工作是用它们的内容填充空的blocks。
在这个例子中, block
标签定义了三个可以被子模版内容填充的block。 block
告诉模版引擎: 子模版可能会覆盖掉模版中的这些位置。
子模版可能看起来是这样的:
{% extends "base.html" %} {% block title %}My amazing blog{% endblock %} {% block content %} {% for entry in blog_entries %} <h2>{{ entry.title }}</h2> <p>{{ entry.body }}</p> {% endfor %} {% endblock %}
extends
标签是这里的关键。它告诉模版引擎,这个模版“继承”了另一个模版。当模版系统处理这个模版时,首先,它将定位父模版——在此例中,就是“base.html”。
那时,模版引擎将注意到 base.html
中的三个 block
标签,并用子模版中的内容来替换这些block。根据 blog_entries
的值,输出可能看起来是这样的:
<!DOCTYPE html> <html lang="en"> <head> <link rel="stylesheet" href="style.css" /> <title>My amazing blog</title> </head> <body> <div id="sidebar"> <ul> <li><a href="/">Home</a></li> <li><a href="/blog/">Blog</a></li> </ul> </div> <div id="content"> <h2>Entry one</h2> <p>This is my first entry.</p> <h2>Entry two</h2> <p>This is my second entry.</p> </div> </body> </html>
请注意,子模版并没有定义 sidebar
block,所以系统使用了父模版中的值。父模版的 {% block %}
标签中的内容总是被用作备选内容(fallback)。
这种方式使代码得到最大程度的复用,并且使得添加内容到共享的内容区域更加简单,例如,部分范围内的导航。
这里是使用继承的一些提示:
- 如果你在模版中使用
{% extends %}
标签,它必须是模版中的第一个标签。其他的任何情况下,模版继承都将无法工作。 - 在base模版中设置越多的
{% block %}
标签越好。请记住,子模版不必定义全部父模版中的blocks,所以,你可以在大多数blocks中填充合理的默认内容,然后,只定义你需要的那一个。多一点钩子总比少一点好。 - 如果你发现你自己在大量的模版中复制内容,那可能意味着你应该把内容移动到父模版中的一个
{% block %}
中。 - If you need to get the content of the block from the parent template, the
{{ block.super }}
variable will do the trick. This is useful if you want to add to the contents of a parent block instead of completely overriding it. Data inserted using{{ block.super }}
will not be automatically escaped (see the next section), since it was already escaped, if necessary, in the parent template. - 为了更好的可读性,你也可以给你的
{% endblock %}
标签一个 名字 。例如:
{% block content %} ... {% endblock content %}
- 在大型模版中,这个方法帮你清楚的看到哪一个
{% block %}
标签被关闭了。 - 不能在一个模版中定义多个相同名字的
block
标签
图书后台管理案例
https://v3.bootcss.com/examples/dashboard/使用这个作为模板修改
在app02创建这个项目
[[email protected] mysite]# vim app02/urls.py
