python - 使用开发服务器的 Appengine BulkLoader 问题

Question

我正在做一些应该很简单的事情，却一遍又一遍地卡住了。将非常简单的 csv 文件上传到我的开发服务器时出现此错误:

Error in WorkerThread-0: app "dev~fbdec" cannot access app "fbdec"'s data

确切的输出是:

这是 app.yaml 文件:

application: fbdec
version: 1
runtime: python
api_version: 1

handlers:
- url: /static
  static_dir: static

- url: /remote_api
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
  login: admin

- url: /.*
  script: fbdec.py

这是执行上传的 shell 调用:

appcfg.py upload_data --config_file=fbdec/fbuploader.py --filename=cols.csv --kind=Cols --has_header --num_threads=1 --url=http://localhost:8080/remote_api fbdec/

这是上传代码:

import cgi
import datetime
import logging
import os

import datetime
from google.appengine.ext import db
from google.appengine.tools import bulkloader
from os import environ


class Grobs(db.Model):
    coleccion = db.TextProperty()
    objeto= db.TextProperty() 
    descripcion = db.TextProperty()

class GrobLoader(bulkloader.Loader):
    def __init__(self):
        bulkloader.Loader.__init__(self, 'Grobs',
                                   [('coleccion', str),  
                                    ('objeto', str),
                                    ('descripcion', str)
                                   ])

class Cols(db.Model):
    coleccion = db.TextProperty()
    descripcion= db.TextProperty() 

class ColLoader(bulkloader.Loader):
    def __init__(self):
        bulkloader.Loader.__init__(self, 'Cols',
                                   [('coleccion', str),
                                    ('descripcion', str)
                                   ])

loaders = [GrobLoader, ColLoader]

这是 cols.csv 文件:

coleccion,descripcion
gafas,descripcion
sombreros,descripcion

我们非常欢迎任何帮助。我不知道我做错了什么。

我在 Mac Osx Leopard 上使用 Appengine 1.5.2。我已经尝试了 python 2.5.4 和 2.6.6(以防万一)。

在此先致谢并致以最诚挚的问候!

启动 dev_appserver 时，传递 --default_partition="" 参数。
