I've run a lot of tests and I couldn't set os.environ['SOME_KEY']
='some value' and have access to it in welcome/model/db.py. If you
can tell me how to do it then I'll test it out.
As I couldn't get it to work, I did the following which I could get to
work.
In gaehandler.py, I added "env['app_engine']='GAE'" to wsgiapp
(env,res):
In main.py, I added "environ['app_engine']='WSGI'" to app_with_logging
(environ, responder):
Then in welcome/model/db.py I could do "if request.env['app_engine']
=='GAE':" which is all I need for my current work.
