Hi,
I want to write a large number of model instances to DB, in a
multi-database setup. The way I am doing this is essentially:
@transaction.atomic
def process_all():
for record in Model.objects.using(DB1).all():
process_one(record)
def process_one(record):
do_something_with(record)
record.save(using=DB2)
The way I understand the docs
(https://docs.djangoproject.com/en/1.8/topics/db/transactions/#controlling-transactions-explicitly)
this should start a transaction when process_all() is entered, and commit
it when process_all() is finished - so all records should be written at
once. However, this is not what happens - no transaction is started, and
all records are written to DB immediately.
Neither ATOMIC_REQUESTS nor AUTOCOMMIT are touched in the settings. FWIW, I
use a Postgres DB and Django 1.7.8. Also, if I replace the
@transactions.atomic decorator with: with transactions.atomic() do: ...,
that doesn't change anything.
What am I missing?
Thanks, Lene
