[SQLObject] column default value

[Andreas K. <an...@ko...>]

Hi!

I'd like to define a default for one of my classes:

class Worktime(SQLObject):
	customer =3D ForeignKey("customer", default=3DWHATDOIPUTHERE)
	task =3D ForeignKey("task")
	...

Now every row of Worktime must have a customer that is not NULL/None,
while the task assignment might be NULL/None (because it's not clear
against what task some time will get billed, while it's clear for which
customer the time was spent).

Now, a _set_customer setter doesn't work, because it needs the
corresponding .task value, and it seems that _set_customer doesn't get
called by Worktime(...)

Supplying a callable default value would seem to be ok, BUT the callable
doesn't get any context (like arguments to the constructor, the row
object).
