Sinatra 事务回调警告中的 Activerecord

Question

带有 activerecord gem 的 Sinatra 项目发出警告：

DEPRECATION WARNING: Currently, Active Record suppresses errors raised
within `after_rollback`/`after_commit` callbacks and only print them
to the logs. In the next version, these errors will no longer be
suppressed. Instead, the errors will propagate normally just like in
other Active Record callbacks.

You can opt into the new behavior and remove this warning by setting:


**config.active_record.raise_in_transactional_callbacks = true**

Gemfile.lock

activemodel (4.2.0)

      activesupport (= 4.2.0)
      builder (~> 3.1)

如何删除这个？谢谢！

Answer 1

错误消息告诉您该怎么做。在 Rails 中，暂时将此行添加到您的应用程序中：

config.active_record.raise_in_transactional_callbacks = true

在 Sinatra 中，您可以直接在ActiveRecord::Base：

ActiveRecord::Base.raise_in_transactional_callbacks = true

请记住，此配置选项本身将在 Active Record 的下一个版本中被弃用。
