[SQLObject] Iheritence and Validation

[konrad Z. <kzi...@gm...>]

Hi,

I have been playing with the inhertence system and have come up
againsts a few chalanges the largest of these being that the process
of creating a subclass instance is not atomic.

I had a hiarchy of

Role(InheritableSQLObject)
Staff(Role)
Professor(Staff)

due to keyword errors the system sucesfully ceated a Role instance and
Staff instance but failed to create a professor instance.

The obvious solution seems to be to do some pre-validation is there a way t=
o get
a list of all the keyword arguments expected by a professor Object?

Then the other question is how to actually implement the validation.
(SQLObject could realy use a before creation hook for this).
