[SQLObject] Re: SQLObject inheritance patch 2

[Oleg B. <ph...@ph...>]

Hi!

   I tried a simplest test.

import SQLObject
from db import db_conn


class Woman(SQLObject.SQLObject):
   _inheritable = 1
   _connection = db_conn

   name = SQLObject.StringCol()


class Wilma(Woman):
   smile = SQLObject.IntCol()


wilma = Wilma.new(name="Wilma", smile=1)
barney = Barney.new(passion=wilma)

woman = Woman(1)
print woman # prints <Wilma 1 childName=None smile=1>, ok
print woman.smile # => 1
print woman.name

Traceback (most recent call last):
  File "test.py", line 10, in ?
    print woman.name
  File "<string>", line 1, in <lambda>
AttributeError: 'Wilma' object has no attribute '_parent'

   Oops. I found many places in the code where _parent attribute is
used, but only one where it is assigned - in new(). Shouldn't it be
assigned in __new__ too?

Oleg.
