Python 使用开发服务器时出现的Appengine散货装载机问题

我正在做一些应该简单的事情，并且一次又一次地陷入困境。将非常简单的csv文件上载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

确切的输出为：

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

此命令用于执行上载的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/

这是上传程序代码：

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

任何帮助都是非常受欢迎的。我不知道我做错了什么

我正在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）

提前感谢并致以最良好的问候

启动dev\u appserver时，传递

--default\u partition=“”

参数。

在较新的SDK上，使用--application=dev~您的应用程序选项。

我最近遇到了同样的问题，因此我创建了一个脚本来执行此操作：

APP=$1 #your app name
IN=$2 #the file containing the data to upload
DIR=$3 #the folder containing your app.yaml
appcfg.py upload_data --email=foobar@nowhere.com --passin --application=dev~$APP --filename=$IN --url=http://localhost:8080/_ah/remote_api $DIR -v

问题在于，为了帮助暴露应用程序在高冗余应用程序名称上使用“s~”前缀可能存在的问题，在开发服务器应用程序中添加了一个“dev~”前缀。理论上，当一切正常时，这些前缀应该是透明的。您可能需要在命令行中提供

--application=

，尽管我不确定是否要在其中包含dev~。谢谢您的解释。我不知道。我试过Robert Kluin的参数，效果也不错。最好的。升级到最新的SDK应该可以解决这个问题。它是最新的。事实上，情况正好相反。我已经返回到一个旧版本（我在某处有一个1.3.5安装程序）进行测试，在那里问题不会出现，并且它在没有添加--default_分区选项的情况下工作。非常感谢。这就解决了问题。感谢您的快速回复。祝你一切顺利；用勾号接受答案，这就结束了问题，让Robert的内心更加快乐。要在GoogleAppEngineLauncher上实现这一点，右键单击应用程序，然后从菜单中选择“信息…”，然后键入“额外标志”-default_partition=并更新。请特别注意，不应添加结尾处的引号。我在Python2.7.3中遇到了类似的问题。除了特殊的例外情况，

没有名为my_model的模块

。这里的详细信息：显然，sdkv1.8.6中的

appcfg.py

不识别此标志。还有其他想法吗？
