sqlalchemy 知识补充

写入用户注册信息的时候可以直接取出信息

def write_info(user,pwd,phone,email):
    aaaa = time.strftime('%Y-%m-%d-%H-%M-%S', time.localtime(time.time()))
    Session = sessionmaker(bind=engine)
    session = Session()
    obj = Users(user_name=user, user_pwd=pwd, user_phone=phone,user_email=email,user_time=aaaa)
    session.add(obj)

    # 写入直接拿出来
    session.flush()
    session.refresh(obj)
    print(obj.user_nid,obj.user_email,obj.user_time)

    session.commit()
