python - 类型错误：remove() 接受 1 个位置参数，但给出了 2 个

Question

我正在用烧瓶开发一个 Python 应用程序，这是我的 DELETE 函数：

@app.route('/DeleteMessage', methods=['GET'])
def DeleteMessage():
    global messages
    application_id = request.args.get('application_id')
    if application_id:
        messages = Message.query.filter_by(user_id=application_id)
    session_id = request.args.get('session_id')
    if session_id:
        messages = Message.query.filter_by(session_id=session_id)    
    message_id = request.args.get('message_id')
    if message_id:
        messages = Message.query.filter_by(message_id=message_id)

    for m in messages:  
        db.session.remove(m)
        db.session.commit()
    return 'Message deleted successfully!'

它向我发送了这样一条错误消息：

TypeError: remove() takes 1 positional argument but 2 were given

问题是什么？
