我想检索一些值,我把数据存储与模型类名称“Ani”,我已经尝试使用下面的脚本来做到这一点,但我有问题。可有人请,帮我一下吧我可以从数据存储检索值

import random 
import getpass 
import sys 

# Add the Python SDK to the package path. 
# Adjust these paths accordingly. 
sys.path.append('/root/google_appengine') 
sys.path.append('/root/google_appengine/lib/yaml/lib') 

from google.appengine.ext.remote_api import remote_api_stub 

from google.appengine.ext import db 
import models 

# Your app ID and remote API URL path go here. 
APP_ID = 'silasanio' 
REMOTE_API_PATH = '/remote_api' 
def auth_func(): 
    email_address = raw_input('Email address: ') 
    password = getpass.getpass('Password: ') 
    return email_address, password 

def initialize_remote_api(app_id=APP_ID, 
          path=REMOTE_API_PATH): 
    remote_api_stub.ConfigureRemoteApi(
     app_id, 
     path, 
     auth_func) 
    remote_api_stub.MaybeInvokeAuthentication() 

def main(): 
    initialize_remote_api() 

    Meanvalue = [] 
    result = db.   ("SELECT * FROM Ani ORDER BY date DESC LIMIT 1") 
    for res in result: 
     Meanvalue = res.mean 
     std_dev = res.stdev 

     print(mean) 


if __name__ == '__main__': 
    main() 

我收到以下错误:

提高KindError(%S \ '' %样 '的那种\没有实现') google.appengine.ext .db.KindError:没有实施种类'Ani'

请,我需要一些帮助。

感谢

您需要导入在其中定义类Ani的文件,然后才能运行查询的数据。
