为什么我不能用ipython访问Django shell中的导入函数？

I have installed ipython in my virtualenv, so python manage.py shell gives my ipython. However, I can't access imports from inside function definitions:

我已经在我的virtualenv中安装了ipython,所以python manage.py shell给了我的ipython。但是,我无法从函数定义内部访问导入:

$ python manage.py shell

Type "copyright", "credits" or "license" for more information.

In [1]: from re import search

In [2]: def my_search(pattern, string):
    return search(pattern, string)
   ...: 

In [3]: my_search('x', 'y')

----> 1 my_search('x', 'y')

/home/wilfred/.envs/drawbridge/lib/python2.7/site-packages/django/core/management/commands/shell.pyc in my_search(pattern, string)
      1 def my_search(pattern, string):
----> 2     return search(pattern, string)
      3 

NameError: global name 'search' is not defined

This works fine if I start ipython directly. Why doesn't it work from the Django shell?

如果我直接启动ipython,这可以正常工作。为什么它不能用于Django shell?
