ruby-on-rails - SQLite3 错误 - 无法回滚 - 没有事务处于事件状态

Question

已解决(见下文)

当我尝试在我的 Ruby on Rails 应用程序(或在控制台中)中创建或销毁一条记录(在 SQLite3 上运行)时，我收到了一个 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

记录存入数据库也抛出这种错误。我尝试删除我的数据库，然后再次创建和迁移它，但它似乎没有任何用处。

如果有任何关于如何修复它的想法，我将不胜感激。我以前从来没有遇到过这样的事情 =(

解决方案

我已经破坏了我的模型并创建了另一个模型。一定是属性名称有些冲突，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 hash =) 谢谢大家!

我的天啊……事实上，字段名称“hash”导致 sqlite3 抛出这个非常无用的错误。棘手的...
