English

Attempting to use a session after it has been closed.

generic

解决方案

  1. 95% 成功率 Create a new session instance. 
    from sqlalchemy.orm import Session
new_session = Session(engine)
  2. 90% 成功率 Use context manager to auto-close. 
    with Session(engine) as session:
    session.add(obj)
    session.commit()

无效尝试

常见但无效的做法:

  1. Calling session.open() which does not exist. 90% 失败

    Session has no open method; must create new session.

  2. Reassigning session variable to same closed object. 80% 失败

    Object still closed; operations fail.
