django模板报错

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命令启动python交互式解释器,导入django template会报错

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

yixiaohan@ubuntu:~/djbk$ python manage.py shell

In [1]: from django import template

In [6]: print rt
my name is yixiaohan
