Root Cause

Attempting to use a session after a rollback without beginning a new transaction.

generic

中文

在回滚后尝试使用会话而未开始新事务。

Workarounds

  1. 95% success Begin a new transaction after rollback. 
    session.rollback()
session.begin()  # Start new transaction
  2. 90% success Use session.begin() context manager to auto-handle rollback. 
    with session.begin():
    session.add(obj)
# Automatically commits or rolls back

Dead Ends

Common approaches that don't work:

  1. Calling session.commit() after rollback. 90% fail

    Session is in invalid state; must begin new transaction.

  2. Ignoring rollback and continuing. 80% fail

    Session remains in aborted state; all operations fail.
