Is there a good way (any way) to hook a db.Model subclass so that it does some magic right before being written to the Datastore, and some reverse magic right when it's read back?
E.g. Say you want to have a big JSON object stored in a TextProperty. Obviously you could JSON and de-JSON it yourself every time you load or save it. But ideally you could hook this code into the class itself, so as soon as it's read from the store the JSON string is gone and a Python object is in its place. Similarly, you could manipulate the Python object and write it back to the store, where it would be quickly re-JSONed prior to hitting BigTable. Or maybe there's another better way to work with and serialize arbitrary Python data (lists, dicts, etc.) without writing the code for it in multiple places...
