Hello all. I did a little searching and did not find something on this explicitly. I'm sure I missed because this must have been discussed.
I have an app that I am making some changes to. There is a model that is changing. What I want to do is change a property from db.BlobProperty to db.ReferenceProperty - yep, that old thing. I find that I can't really load any of the old data because appengine.ext.__init__ wants to do some validation which fails. It is using the new model to validate the old data. This sort of make sense, but it is not as pythony as I would have imagined. So, is there a way to do this? Of course, I could just add new attributes and do the migration that way. However, that leaves deprecated attributes in my model, I don't like the design. Further question ... let's say I did go that route. Could I later remove these attributes, or would the db fail them through validation? Thanks for your time and I appreciate your insight. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
