Question

我正在做一些应该简单的事情并且一遍又一遍地被困住。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

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。我无法弄清楚我做错了什么。

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）。

提前致谢和最诚挚的问候！

Answer 1

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

Answer 2

在较新的SDK上，使用--application = dev~your-app选项。

Answer 3

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
