# 包含静态和动态的内容，动态内容就是模板变量，在将模板发送给用户之前，需要将动态部分替换成相应的值

# 在Shell中使用Django模板，不应该直接使用Python REPL

例如：这样会报错：

~$ python3
Python 3.6.7 (default, Oct 22 2018, 11:32:17)
[GCC 8.2.0] on linux

>>> from django import template
>>> template.Template("My name is {{name}}.")

应该在Django的shell里面使用模板：

操作如下：

toohoo@ubuntu:~/PycharmProjects/SecondDjango$ python manage.py shell
Python 2.7.15rc1 (default, Nov 12 2018, 14:31:15)
[GCC 7.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django import template
>>> t = template.Template('My name is {{name}}.')     #stept1
>>> c = template.Context({'name':'Bill'})                       # stept2
>>> t.render(c)                                                                  #stept3
u'My name is Bill.'

在Pycharm里面使用的方法是：

首先是设置模板：

MyTemplate.py

from django.http import HttpResponse
from django import template

def simpleTemplate(request):
    t = template.Template('My name is {{name}}.')
    c = template.Context({'name': 'Bill'})
    return HttpResponse(t.render(c))

然后在urls.py里面设置映射路径

from django.conf.urls import url
from django.contrib import admin
from .views import First
from .views import ServerTime
from .views import Dynamicurl
from .views import MyTemplate
# 动态URL的使用
urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^hh/',First.index),
    url(r'^time/$',ServerTime.currentDateTime),
    url(r'^$',ServerTime.currentDateTime),
    url(r'^time1$',ServerTime.currentDateTime),
    #url(r'^fun/1$',Dynamicurl.fun1),
    #url(r'^fun/2$',Dynamicurl.fun2),
    #url(r'^fun/3$',Dynamicurl.fun3),
    # 映射变成正则表达式
    url(r'^fun/(\d{1,3})/$',Dynamicurl.fun),
    url(r'^simpleTemplate/$',MyTemplate.simpleTemplate)
]

然后确定启动服务器，访问http://127.0.0.1:8000/simpleTemplate/

就可以得到：My name is Bill.
