During handling of the above exception, another exception occurred:

if settings.TEMPLATE_DEBUG and origin is None:

% (desc, ENVIRONMENT_VARIABLE))

django.core.exceptions.ImproperlyConfigured: Requested setting TEMPLATE_DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

解决方法一:

先导入settings

>>> from django.conf import settings

>>> settings.configure()

>>> from django import template
>>> t = template.Template(‘My name is {{ name
}}.‘)
>>> c = template.Context({‘name‘:
‘yixiaohan‘})
>>> print t.render(c)
My name is yixiaohan.
>>> c = template.Context({‘name‘:
‘xiaowangge‘})
>>> print t.render(c)
My name is xiaowangge.

解决方法二:

使用python manage.py shell启动
Python交互式解释器(实际上启动的是Ipython)

python manage.py shell
