备注：启用django模板系统许要在settings.py中进行模板配置
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. os.path.join(os.path.dirname(__file__), ‘templates‘).replace(‘\\‘, ‘/‘), )
