Unable to upload a Django project to Google App Engine

Question

I am trying to test the codes of the project.

I run the following code

$appcfg.py update masicode/

I get the following error

Scanning files on local disk.
Initiating update.

How can you upload Django project successfully to Google App Engine?

Answer 1

Looks like login/permissions problem.

HTTP Error 403: Forbidden
You do not have permission to modify this app (app_id=u'so').

Your appID should be same as the one you have registered in Google App Engine. Your mail and password same as credentials that you've used to register it.
Is http://so.appspot.com/ yours?

Answer 2

Did you develop it specifically for App Engine using a modified Django library such as http://code.google.com/p/google-app-engine-django/? App Engine is a different environment than your standard Python install and apps that were not developed for it will not work (and possibly deploy) correctly.

Does the app run correctly in the App Engine development environment?
