Django4(Template示范)

Django4(Template示例)
1. Template(views.py

   from django.template import Template, Context
   from django.http import HttpResponse
   import datetime

   def current_datetime(request):
       now = datetime.datetime.now()
       t = Template("<html><body>It is now {{current_date}}.
          </body></html>")
       html = t.render(Context({'current_date': now}))
       return HttpResponse(html)

2. urls.py

   from django.conf.urls.defaults import patterns, include, url
   from mysite.views import current_datetime_now

   urlpatterns = patterns('',
       # set now time now
       ('^timenow/$', current_datetime_now),
   )

views.py

   from django.template.loader import get_template
   from django.template import Context
   from django.http import HttpResponse
   import datetime

   def current_datetime_now(request):
       now = datetime.datetime.now()
       t = get_template('current_datetime.html')
       html = t.render(Context({'current_date': now}))
       return HttpResponse(html)

   templates/current_time.html

   <html>
       <body>
           It is now {{ current_date }}.
       </body>
   </html>

settings.py

   import os
   TEMPLATE_DIRS = (
       #'/home/tony/djcode/mysite/templates',
       os.path.join(os.path.dirname(__file__), \
         'templates').replace('\\','/'),
    )

3. 继续改进views.py

   from django.shortcuts import render_to_response
   import datetime

   def current_datetime_shortcut(request):

       now = datetime.datetime.now()
       return render_to_response('current_datetime.html', \
             {'current_date':now})
