HI All!
When I use my own command with manage.py and got any psycopg2
exception on commit, not other exception, I can't create any object in
model after rollback even if I do
transaction.enter_transaction_management() and
transaction.managed(True)
How can I save and commit data after psycopg2.OperationalError
exception?
cursor = connection.cursor()
transaction.enter_transaction_management()
transaction.managed(True)
try:
# import log initialization
import_log = ImportLog.objects.create(registry=registry,
md5sum=md5sum(src), size=os. stat(src).st_size,
commit_date_begin=datetime.datetime.now())
transaction.commit()
# save all objects
for obj in objects:
obj.save()
# write data to import log
import_log.commit_date_end = datetime.datetime.now()
import_log.save()
transaction.commit()
except:
transaction.rollback()
transaction.leave_transaction_management()
# HOW TO CREATE SOME OBJECT HERE???
# THIS CODE DOES NOT WORK if psycopg2.OperationalError exception
raised, WHY?
cursor = connection.cursor()
transaction.enter_transaction_management()
transaction.managed(True)
import_log = ImportLog.objects.get(registry=registry,
md5sum=source_md5sum)
import_log.rollback_date = datetime.datetime.now()
import_log.rollback_savepoint = object_count
import_log.save()
