Is there any way to store in a column the result of a call of an
object method?
I have seen something similar here.

i = 0
def mydefault():
    global i
    i += 1
    return i

t = Table("mytable", meta,
    # function-based default
    Column('id', Integer, primary_key=True, default=mydefault),

    # a scalar default
    Column('key', String(10), default="default")
)

But actually i would like to call a method that belongs to the object
that i am saving, not a static function.

All the best,
Andrea
