[SQLObject] _init method

[Daniel E B. <da...@li...>]

Hello all I have been playing with SQLObject again because I just 
redesigned a rather large database. I was wondering if there was a way 
to tell whether something was fetched or inserted into the database with 
the _init method. Also are there hook methods for doing anything special 
with SELECT, INSERT, UPDATE and DELET? I have some special fields that 
are tacked onto every table that I use: createdOn, createdBy, 
modifiedOn, modifiedBy, partner_id, and tag. I would like to be able to 
add things to each type of query that utilizes these fields. Also, I 
cannot seem to be able to pass in a transaction when instantiating an 
SQLObject class. Some help there would be nice too. I was trying 
something like:

conn = Foo._connection
trans = conn.transaction()
Foo(bar=0, biz=1, baz=sqlbuilder.func.NOW(), connection=trans)
trans.rollback()

when overriding _init and printing out some stuff the connection param 
is None.

Thanks for the Help,
Dan
