ruby-on-rails - 我在 ActiveRecord 中的保存方法出现 Rails 错误

Question

我在调用保存方法时发现了这个错误

我的 Rails Envi：Rails 3.2.5、sqlite 3.7.12（在 GemFile 1.3.6 中）、最新的 ActiveRecord

提前谢谢你。

ActiveRecord and newer versions of SQLite both support nested transactions, but the AR/SQLite adapter does not.

A surprising omission from the docs, given that SQLite is the default DB!
