python - 命名空间中的名称如何是未定义的 Python？

Question

我在尝试关注http://neomodel.readthedocs.org/en/latest/getting_started.html#connecting时遇到了一个可笑的错误

我刚刚从这个环境中卸载了 neo4django，因为它的名称为 StringProperty，我正在尝试为 neo4j 创建一个类：

In [8]: from neomodel import StringProperty as SP

In [9]: class Person(StructuredNode):
   ...:     name = SP()
   ...:     
---------------------------------------------------------------------------
NameError                                 Traceback (most recent call last)
/home/cchilders/.local/virtualenv/another_neo4django_attempt/local/lib/python2.7/site-packages/django/core/management/commands/shell.pyc in <module>()
----> 1 class Person(StructuredNode):
      2     name = SP()
      3 

/home/cchilders/.local/virtualenv/another_neo4django_attempt/local/lib/python2.7/site-packages/django/core/management/commands/shell.pyc in Person()
      1 class Person(StructuredNode):
----> 2     name = SP()
      3 

NameError: name 'SP' is not defined

In [10]: S
%%SVG           StopIteration   SyntaxError     SystemExit
SP              StringProperty  SyntaxWarning   
StandardError   StructuredNode  SystemError 

如您所见，自动完成功能证明名称存在。这个新模型是特定的还是存在一个未定义的名称的一般 Python 原因？谢谢
