I have some requirements like this. One table model is:
class Demo(Base): jsondata = Column(Text) This column "jsondata" is used for saving json data. And this Model would be used anywhere by many developers. I want to load it to a Python object when I query and dump it to string when I insert or update table automatically. Now I has make it the first step by using event "create_instance" or "translate_row", but I have no idea to solve the insert or update problem. It may be typical way that make some agreements with other engineers about how to use this filed. But I think there is a better way :) -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
