Question

我正在使用sails @ beta。

我正在尝试创建下面的几个Room模型（参见定义），问题是我可以成功创建具有相同属性“name”的Room模型，尽管属性“name”具有唯一的验证。

在下次重新启动'sails'服务器之前未检测到验证，然后我收到此输出：

C:\eMali_dev\server>sails lift

Express midleware for passport
Waterline encountered a fatal error when trying to perform the `alter` auto-migration strategy.
In a couple of seconds, the data (cached in memory) will be logged to stdout.
(a failsafe put in place to preserve development data)

In the mean time, here's the error:

Error (E_UNKNOWN) :: Encountered an unexpected error:

这是帆的一个错误，它已修复。谢谢大家

Answer 2

您需要将数据库从默认磁盘数据库更改为您选择的数据库。我遇到了类似的问题，并从＆＃34;磁盘＆＃34; to＆＃34; MongoDB＆＃34;解决了我的问题。似乎默认数据库无法强制执行唯一约束。

我希望它能解决你的问题。
