[Twisted-Python] design question

I've written my first Twisted Server, which accept request from
clients, does DB queries, sends response back and logs some events in
DB. I wonder, if my design was good.
Basically, I have a Factory where is db connectionPool created and
Protocol(basic.LineReceiver), which processes requests and sends data
In Protocol, I instantiate my utility object which I try to keep
independent from twisted framework, so it can be easily used
somewhere else or can be replaced by other class.
def m(self, *args, **kwargs ):
d = self.getData(params=kwargs['params'])
except Exception, e:
log.msg('Unknown error in m:', e)
def getData(self, *args, **kwargs):
obj = MyObj(self.db)
What I don't like, I must pass db variable to obj.getDataFromDb and
may be other function called there. I think it would be better obj =
MyObj(self.db), but it doesn't work and runInteraction passes
automatically db variable to interaction method.
I'm new to Python and Twisted and would appreciate your advises.
