Hi, I am seeing a similar problem.
Below is the settings file and the stack trace. This error seems to come and go. I don't make any changes and it appears and then goes without any change. It seems to have to do with writing to the database. Can someone explain what the error is to help me understand what to change? Thanks, Ralph The typical code is something like this: entry.ip = request.META["REMOTE_ADDR"] entry.eventid = int(event_id) entry.put() The settings.py file is: # Copyright 2008 Google Inc. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # You may obtain a copy of the License at # # http://www.apache.org/licenses/LICENSE-2.0 # # Unless required by applicable law or agreed to in writing, software # distributed under the License is distributed on an "AS IS" BASIS, # WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. # See the License for the specific language governing permissions and # limitations under the License. # Django settings for this project. import os DEBUG = True TEMPLATE_DEBUG = DEBUG ADMINS = ( ('XXX', 'x...@gmail.com'), ) MANAGERS = ADMINS DATABASE_ENGINE = '' # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'ado_mssql'.
