django模板報錯
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.
直接python命令啓動python交互式解釋器,導入django template會報錯

解決方法一:
先導入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.
解決方法二:
使用python manage.py shell啓動 Python交互式解釋器(實際上啓動的是Ipython)
python manage.py shell
yixiaohan@ubuntu:~/djbk$ python manage.py shell
