如何使用Python将数据加载到本地开发服务器？

我知道GAE帮助网站中详细介绍了这一点。这对我不起作用。我对Python有点生疏。但我也知道进口是如何运作的。实体模块就在加载程序所在的同一文件夹中。那么GAE脚本在做什么

这是我的加载器：

from google.appengine.ext import db
from google.appengine.tools import bulkloader
import entities

class CardLoader(bulkloader.Loader):
    def __init__(self):
        bulkloader.Loader.__init__(self, 'Card',
            [('english', str),
            ('translation', str)
            ])

loaders = [CardLoader]

下面是名为entities.py的文件中的内容

from google.appengine.ext import db

class Card(db.Model):
    english = db.StringProperty(required=True)
    translation = db.StringProperty(required=True)

下面是.csv文件中的一小部分内容

"cardId","english","translation"
"3994","face","la cara"
"4027","art","el arte"

我的Python版本：

Python 2.5.4 (r254:67916, Dec 23 2008, 15:10:54) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

以下是我在Windows上的命令：

python c:\Program Files\Google\Google\u appengine\appcfg.py 上传数据-config\u file=card\u loader.py-url -文件名=card\u data.csv-种类=卡片

以下是输出：

回溯描述了一个错误：未找到模块实体。你的模特就在那里吗？如果是这样，您必须确保可以找到它，并在需要时将其目录添加到sys.path。

它实际上位于本地路径中。appcfg.py在windows上的行为是否有所不同？我将尝试FQ路径。我必须这样做：导入sys import os\u root\u dir=os.path.dirnameos.path.realpath文件sys.path.insert0，\u root\u dir导入实体
