But, is my design mistake ?
I must use ever save_or_update() function?
In my case, I have two process working over the same "class of
bussines object".
I do a query, which return me an object list and I call to other
function which pass one parameter (id) and this function do other
query over the same class.
i.e.:
Table -> Person
person_list = my_service.get_people()
for p in person_list:
process_person(p.id)
....
def process_person(id):
person = my_service.get_person()
....
do something with person
....
session.save(person) # here, raise exception:
InvalidRequestError: Instance... already persistent
session.flush([person])
Now, I chage session.save_or_update(person), and this work fine.
