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 :)
