Problema de Appengine BulkLoader con el servidor de desarrollo

Question

Estoy haciendo algo que debería ser simple y atascarse una y otra vez. Estoy consiguiendo este error al subir archivos CSV bastante simples para mi servidor de desarrollo:

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

El ser exacto de salida:

Este es el archivo app.yaml:

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 

Esta es la llamada de shell para realizar la carga:

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/ 

Este es el código de subida por

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] 

Y esto el archivo cols.csv:

coleccion,descripcion 
gafas,descripcion 
sombreros,descripcion 

Cualquier ayuda será muy bienvenida. No puedo entender lo que estoy haciendo mal.

Estoy usando Appengine 1.5.2 en Mac Osx Leopard. He probado tanto Python 2.5.4 como 2.6.6 (por si acaso).

Gracias de antemano y mis mejores deseos!

Answer 1

Al iniciar dev_appserver, pase el parámetro --default_partition="".

Answer 2

En el SDK más nuevo, use la opción --application = dev ~ your-app.

Answer 3

Recientemente tuve el mismo problema, por lo tanto, he creado un script para hacer esto:

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
