GAE Blob最大檔限制

當我們使用GAE(BlobProperty class)的DB存取圖片或檔案時，須注意單筆資料1MB的上限!!

使用remote_api直接調用遠端的db model

#!/usr/bin/env python
#
import os
import sys

# Hardwire in appengine modules to PYTHONPATH
# or use wrapper to do it more elegantly
appengine_dirs = ['/Applications/blah/blah/google_appengine'...]
sys.path.extend(appengine_dirs)
# Add your models to path
my_root_dir = os.path.abspath(os.path.dirname(__file__))
sys.path.insert(0, my_root_dir)

from google.appengine.ext import db
from google.appengine.ext.remote_api import remote_api_stub
import getpass

from models.mystuff import Foo

APP_NAME = 'my-app'
os.environ['AUTH_DOMAIN'] = 'gmail.com'
os.environ['USER_EMAIL'] = 'me@gmail.com'

def auth_func():
 return (raw_input('Username:'), getpass.getpass('Password:'))

# Use local dev server by passing in as parameter:
# servername='localhost:8080'
# Otherwise, remote_api assumes you are targeting APP_NAME.appspot.com
remote_api_stub.ConfigureRemoteDatastore(APP_NAME,
 '/remote_api', auth_func)

# Do stuff like your code was running on App Engine

foos = Foo.all().fetch(100)
for foo in foos:
 foo.note = 'Hello World!'
db.puts(foos)

由ConfigureRemoteDatastore換掉所操作的model，由ConfigureRemoteDatastore

對model定義，code中沒看到定義 Foo
