doesn't this help?:
def __init__(self, a, b, c):
self.a = a
self.b = b
self.c = a + b

I've read the documentation but could not find it so I'm asking here.
I have a table in models and there is a column in that model that it's
value shuld be changed when there is an insert or update on that table.
here is an example:
-----------
class Sometable(DeclarativeBase):
__tablename__ = 'sometable'
id = Column(Integer, autoincrement=True, primary_key=True)
a = Column(Unicode(50))
b = Column(Unicode(50))
c = Column(Unicode(100))
-------
in that table, I want only set the values of a and b and value of c
should be c = a + b
I think I should write a function but where should I put that function?
it helps only when creating a new record but not updating or setting the
fields like this.
-------------------------------
somerecord = model.SomeTable()
somerecord.a = 'something'
somerecord.b = 'otherthing'
model.DBSession.add(somerecord)
-------------------------------
I need to write some function that should run when a record updated or
inserted to set other fields depending of some fields.
