模板是一个文本，用于分离文档的表现形式和内容。 模板定义了占位符以及各种用于规范文档该如何显示的各部分基本逻辑（模板标签）。 模板通常用于产生HTML，但是Django的模板也能产生任何基于文本格式的文档。
来一个项目说明
1、建立MyDjangoSite项目具体不多说，参考前面。
2、在MyDjangoSite（包含四个文件的）文件夹目录下新建templates文件夹存放模版。
3、在刚建立的模版下建模版文件user_info.html
<html>
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<title>用户信息</title>
<head></head>
<body>
<h3>用户信息：</h3>
<p>姓名：{{name}}</p>
<p>年龄：{{age}}</p>
</body>
</html> 4、修改settings.py 中的TEMPLATE_DIRS
导入import os.path
添加 os.path.join(os.path.dirname(__file__), 'templates').replace('\\','/'),
TEMPLATE_DIRS = (
# Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
#"E:/workspace/pythonworkspace/MyDjangoSite/MyDjangoSite/templates",
os.path.join(os.path.dirname(__file__), 'templates').replace('\\','/'),
) 5、新建视图文件view.py
#vim: set fileencoding=utf-8:
#from django.template.loader import get_template
#from django.template import Context
#from django.http import HttpResponse
from django.shortcuts import render_to_response
def user_info(request):
name = 'zbw'
age = 24
#t = get_template('user_info.html')
#html = t.render(Context(locals()))
#return HttpResponse(html)
return render_to_response('user_info.html',locals()) 6、修改urls.py
from django.conf.urls import patterns, include, url
from MyDjangoSite.views import user_info
# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'MyDjangoSite.views.home', name='home'),
# url(r'^MyDjangoSite/', include('MyDjangoSite.foo.urls')),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
# url(r'^admin/', include(admin.site.urls)),
url(r'^u/$',user_info),
) 7、启动开发服务器
基本一个简单的模版应用就完成，启动服务看效果！
效果如图：
模版的继承
减少重复编写相同代码，以及降低维护成本。直接看应用。
1、新建/templates/base.html
<html>
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<title>{% block title %}{% endblock %}</title>
<head></head>
<body>
<h3>{% block headTitle %}{% endblock %}</h3>
{% block content %} {% endblock %}
{% block footer %}
<h3>嘿，这是继承了模版</h3>
{% endblock%}
</body>
</html> 2、修改/template/user_info.html,以及新建product_info.html
urser_info.html
{% extends "base.html" %}
{% block title %}用户信息{% endblock %}
<h3>{% block headTitle %}用户信息：{% endblock %}</h3>
{% block content %}
<p>姓名：{{name}}</p>
<p>年龄：{{age}}</p>
{% endblock %} product_info.html
{% extends "base.html" %}
{% block title %}产品信息{% endblock %}
<h3>{% block headTitle %}产品信息：{% endblock %}</h3>
{% block content %}
{{productName}}
{% endblock %} 3、编写视图逻辑，修改views.py
#vim: set fileencoding=utf-8:
#from django.template.loader import get_template
#from django.template import Context
#from django.http import HttpResponse
from django.shortcuts import render_to_response
def user_info(request):
name = 'zbw'
age = 24
#t = get_template('user_info.html')
#html = t.render(Context(locals()))
#return HttpResponse(html)
return render_to_response('user_info.html',locals())
def product_info(request):
productName = '阿莫西林胶囊'
return render_to_response('product_info.html',{'productName':productName}) 4、修改urls.py
from django.conf.urls import patterns, include, url
from MyDjangoSite.views import user_info,product_info
# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'MyDjangoSite.views.home', name='home'),
# url(r'^MyDjangoSite/', include('MyDjangoSite.foo.urls')),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
# url(r'^admin/', include(admin.site.urls)),
url(r'^u/$',user_info),
url(r'^p/$',product_info),
) 5、启动服务效果如下：
