What I ususally do is a Model object with properties, something like 
this: http://rafb.net/paste/results/LwMH9m76.html
Then in my Controller I have a method to parse the form, something like :

def parse_form(self, themodelobject) :
    errors = []
    for col in themodelobject.columns:
          setattr(themodelobject, col, self.params.get[col])
       except Exception, e:
    return errors

def add(self):
    errors = parse_form(myModel())
    if not errors:

(it's a basic and limited example, but it show you the principle)
