# I've set echo=True when doing create_engine, so I can see all the sql stmt
# DBSession is ScopeSession(thread_local) and autocommit is False
session = DBSession()
session.add(somemodel)
#
try:
session.flush()
raise Exception()
session.commit()
except SQLAlchemyError as e:
session.rollback()
finally:
session.close()
根据 SQLAlchemy 文档:
The close() method issues a expunge_all(), and releases any transactional/connection
resources. When connections are returned to the connection pool, transactional state is
rolled back as well.
我希望在执行“session.close()”时看到日志“回滚”
