[google-appengine] Re: How to design data model
Niklas (et al), I am very pleased to find your link below of djangoforms because it seems so promising for my app. http://code.google.com/appengine/articles/djangoforms.html But when I enter the code for the app I get lots of warnings and finally the shopping list app stops with the following messages in the log. INFO 2012-05-28 18:27:04,446 dev_appserver_multiprocess.py:647] Running application dev~shoppinglist on port 8083: http://localhost:8083 INFO 2012-05-28 18:27:04,447 dev_appserver_multiprocess.py:649] Admin console is available at: http://localhost:8083/_ah/admin INFO 2012-05-28 18:27:29,059 dev_appserver.py:2904] GET / HTTP/1.1 200 - I am using Python2.7 and webapp2 for the first time and I fear there is some conflict with this django forms example. I seem to remember reading that webapp2 does not support cgi, for example. Btw, I am getting the following warnings also in the log. Can they be ignored? /Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/api/search/search.py:232: UserWarning: DocumentOperationResult._CODES is deprecated.
