Root Cause

Attempting to execute a query on a session that has been explicitly closed or has ended its transaction.

generic

中文

尝试在已明确关闭或事务已结束的会话上执行查询。

Workarounds

  1. 95% success Create new session 
    Create a new session instance: new_session = Session(); new_session.query(User).all()
  2. 85% success Check session is_active 
    Ensure the session is not closed prematurely by checking session.is_active before queries.

Dead Ends

Common approaches that don't work:

  1. Trying to reopen session 80% fail

  2. Using non-existent method 90% fail
