Question

我几分钟前完成了我的项目。我做了一个提交，之后我想清除DB因为有很多测试记录。所以我在DBconsole：

中运行了这个

sqlite> delete from users where id;
sqlite> delete from users where id=1;
sqlite> delete from posts where id=1;
sqlite> delete from votes where id=1;

在此之后我的项目不起作用（（。它返回：

我们很抱歉，但出了点问题。

如果您是应用程序所有者，请检查日志以获取更多信息。在每一页，甚至静态!!!!

明天我需要我的项目。我从Git恢复，但错误并没有消失。

我的日志看起来像这样：

您使用此声明删除了所有用户。

delete from users where id;

所以日志中的行

User Load (0.3ms)  SELECT "users".* FROM "users" WHERE "users"."id" = ? LIMIT 1  [["id", 8]]

无法加载ID为8的用户，因为该表为空。也许您需要添加一个对您的程序起作用至关重要的用户。

我杀了我的项目BD，但明天我需要它
