我有两个应用程序……一个旧的 Rails 2.3.14 应用程序和相同的代码更新到 Rails 3.1.0。 (我知道 6.x 是最近的,但我会先迈出一小步)
我轮流针对同一个 postgres 数据库测试这两个应用
当我在控制台中运行 2.3 应用程序并启动 Rails 控制台时,我得到了一个结果...
>> User.first
=> #<User id: 433, login: "danny.vally", email: "danny.vally@gmail.com", crypted_password: "xxxxxxxxxxxxxxxxxxxxxxx", salt: "yyyyyyyyyyyyyyyyyyyyyyyy", created_at: "2015-12-11 10:56:17", updated_at: "2016-10-01 00:00:23", remember_token: nil, remember_token_expires_at: nil, contact_id: 1222222, created_by: 333, updated_by: 434, cashier_code: 9555, can_login: false, last_logged_in: "2016-03-05", shared: false, reason_cannot_login: "Account disabled due to 280 days of inactivity.">
太好了...我可以看到数据库并在 User 模型中看到一个用户。
现在,在 Rails 3.1.0 版本上(指向同一个数据库......退出另一个应用程序后......我在 rails 控制台中得到以下内容......

我已经为此倾注了好几个星期,但我被难住了。有希望吗?这是 3.1.0 中可能已在某些更高版本中修复的某种故障吗?也许3.1.1?还是2.3.14不能升级到3.1.0?
感谢您抽出宝贵时间。
