模板加载
在mysite下新建一个templates文件夹，然后在setting.py添加以下内容：
import os.path
TEMPLATE_DIRS = (
os.path.join(os.path.dirname(__file__), 'templates').replace('\\','/'),
)
模板编写
urls.py
from django.conf.urls import patterns, include, url
from mysite.views import hello
from books.views import current_datetime
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'mysite.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^admin/', include(admin.site.urls)),
url(r'^hello/$', hello),
url(r'^current_datetime/$',current_datetime),
)
current_datetime.html
<html><body>It is now {{ current_date }}.</body></html>
views.py
from django.shortcuts import render
from django.template import Context
from django.template.loader import get_template
from django.http import HttpResponse
import datetime
# Create your views here.
def current_datetime(request):
now = datetime.datetime.now()
t = get_template('current_datetime.html')
html = t.render(Context({'current_date':now}))
return HttpResponse(html)
针对current_datetime改进版，使用了render_to_response()和locals()函数
def current_datetime(request):
current_date = datetime.datetime.now()
return render_to_response('current_datetime.html', locals())
运行python manage runserver
在浏览器输入http://127.0.0.1:8000/current_datetime/，即可看到网页 输出当前的时间
base.html
