Hi. As a rule, when someone uses the term "code smell", that's a "cliche smell". Google bundles django with AppEngine, and django messes with the internals of Python like crazy, so Google hopefully does think it's safe in some cases. I want to put some data into the datastore. Depending on the value of that data, I want it to map to a different class when I get it back. Changing the __class__ attribute currently works. I posted this question for two reasons: - to find out whether or not this approach was likely to break in some cases or with future versions of DataStore API. - because changing __class__ feels hackish and I was hoping someone might suggest a better approach -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
