Hi,
I would like to build an or_ statement using a for cycle, something like the
following:
employeetask_or = or_(False) # to exclude everything not satisfied
by later appended criteria, is this needed or empty or_() is fine?
for period in periods.all():
period.close(session, machine_id)
employeetask_or.append(and_(EmployeeTasks.work_id==period.operation.work_id,
EmployeeTasks.is_reparation==period.operation.is_reparation))
qry = session.query(EmployeeTasks).filter(and_(employeetask_or,
EmployeeTasks.paused==None, EmployeeTasks.finished==0))
of course(?) this does not work, and I don't really have any ideas after
inspecting or_'s methods. Could someone give me a hand, please?
(this inefficient for cycle is needed for a very efficient bulk update)
Viktor
