Question

我从Django学到的控制器中的一种调试方法是实际打印出控制器本身的变量。但是，我意识到这种方法在rails中并不实用，因为默认的rails webserver非常冗长，而且这让我很难追踪。

仅供参考我阅读了有关rails调试页面的内容，但大多数调试技术都存在于VIEW层中（例如＆lt;％@ myvar.debug％＆gt;）。我希望能够看到控制器内的变量状态，我不想使用rails调试器，因为它对于这么简单的东西来说太过分了。

我的问题是：是否有一个变量可以设置为减少每个页面服务生成的语句，如下所示？

您应该可以更改config/environments/*.rb文件中的日志记录级别。

请参阅：http://guides.rubyonrails.org/debugging_rails_applications.html#log-levels了解不同的日志级别。
