Django(Django错误整理)

1. Settings cannot be imported, because environment variable
DJANGO_SETTINGS_MODULE is undefined.
解决方法:

   >>> from django.template import Template, Context 
   >>> from django.conf import settings
   >>> settings.configure() //添加这两句
   >>> t = Template('My name is {{ my_name }}.') 
   >>> c = Context({'my_name': 'Daryl Spitzer'}) 
   >>> t.render(c)

其实还有一种方法，可以省去添加这两句:
$ cd ~//djcode/mysite
$ python manage.py shell
这之后也同样启动了一个python交互器，只不过它告诉了django使用哪些配置文件:

   >>> from django.template import Template
   >>> t = Template('My name is {{ name }}.')
   >>> print t
