I write my own with fair regularity... they're a good way of reducing  
boilerplate code (in addition to the magic they can be used for):

def tryCommit(f):
     @wraps(f)
     def wrapper(self, *args, **kwargs):
         try:
             ret=f(self, *args, **kwargs)
         except:
             self.connection.rollback()
             raise
         else:
             self.connection.commit()
             return ret
     return wrapper
