ruby-on-rails – SQLite3错误 – 无法回滚 – 没有事务处于活动

当我试图在我的Ruby on Rails应用程序(或在控制台中)创建或销毁记录(在SQLite3上运行)时,我得到一个SQL异常：

irb(main):014:0> ApiCache.all
=> []
irb(main):015:0> ApiCache.create(:hash => 'qwe',:contents => 'asd')
SQLite3::SQLException: cannot rollback - no transaction is active

记录保存到数据库中,但也会抛出此类错误.我试图删除我的数据库然后再次创建和迁移它,但它似乎没有任何好处.

我真的很感激有关如何修复它的任何想法.我以前从未遇到过这样的事情=(

解

我摧毁了我的模型并创建了另一个模型.必须在属性名称中有一些冲突,因为新的现在有fp：string contents：text并且工作得很好.可能是破坏SQLite的词哈希=)谢谢你们！
