命名空间中的名称如何未定义 Python？

Question

我在尝试关注 http://neomodel.readthedocs.org/en/latest/getting_started.html#connecting

时遇到了一个荒谬的错误

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

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，自动完成功能证明该名称存在。这个新模型是特定的还是有一个普遍的 Python 原因导致存在的名称未定义？谢谢

>>> from neomodel import StringProperty as SP
>>> from neomodel import (StructuredNode, IntegerProperty,
    RelationshipTo, RelationshipFrom)
>>> 
>>> class Person(StructuredNode):
    name = SP()

命名空间中的名称如何未定义 Python？

how can a name in the namespace be undefined Python?
