how about:
from sqlalchemy import inspect
mapper = inspect(obj)
session.expire(obj, [col.key for col in mapper.primary_keys])
make_transient(obj)

Right now I am taking test run object from local database, then I
call expunge on that object (cascade is set to expunge).
then I put this object into this python method :
def _reset_primary_keys(self, test_run):
make_transient(test_run)
test_run.ID= None
if test_run.OrderNumber:
make_transient(test_run.OrderNumber)
test_run.OrderNumber.ID= None
for equipmentin test_run.TestEquipments:
make_transient(equipment)
equipment.ID= None
for trdin test_run.TestRunToDevs:
make_transient(trd)
trd.ID= None
if trd.TestedDut:
make_transient(trd.TestedDut)
trd.TestedDut.ID= None
for test_stepin trd.TestSteps:
make_transient(test_step)
test_step.ID= None
for test_resultin test_step.TestResults:
make_transient(test_result)
test_result.ID= None
This method reset all primary keys, so I can merge it into master
database which will generate new primary keys. Is there a better or
easier way how to do it?
