我使用迁移文件在rails应用程序中创建了一个名为Flowlogs的表。我也将数据馈入了Rails控制台中的该表。突然，当我尝试在Rails控制台中手动输入数据时，我得到了错误。
我创建了一个名为“ flowlogs”的表，该表中有两列，名称分别为vpc_id和flowlog_id。 我已经登录到Rails控制台，并给出了a = Flowlogs.new（），然后给出了a.vpc_id =“ 1234”和a.flowlog_id =“ a1234”，最后给出了a.save。这已成功工作，并且通过使用命令Flowlogs.all对我进行了交叉检查。它显示了输出。但是过了一段时间，当我登录控制台并提供Flowlogs.all时，它一直抛出错误。
最重要的是，当我登录mysql控制台并检查是否有一个包含我在rails控制台中手动输入的数据的表时
我的数据库名称是Fusion。
