In a ActiveRecord transaction block, how do I get to know the number of records that were created/updated/rollbacked? 在ActiveRecord事务块中，我如何知道已创建/更新/回滚的记录数？ for specific model. 针对特定型号。

This information is needed to know the history of what happened during the transaction job and report to the user. 需要此信息来了解交易工作期间发生的事情的历史并向用户报告。

1 个解决方案

A transaction either succeeds entirely, or fails and the database is rolled back to the state before the transaction. 事务要么完全成功，要么失败，并且数据库回滚到事务之前的状态。

There is no notion of partial completion for a transaction. 没有交易的部分完成的概念。
