如何在Rails控制台中打印出CarrierWaves配置值？

I have a running Rails app with the CarrierWave gem.

我有一个运行Rails应用程序与CarrierWave宝石。

I am able to see the CarrierWave class in the Rails console, and identify methods etc, but am not able to figure out how to print the configuration variables I set in my app. I looked over the docs and have set the config working correctly as per http://www.rubydoc.info/gems/carrierwave#Using_Amazon_S3 but was not able to figure out how to display config settings in the Rails console. It would allow on the fly changes and testing.

我能够在Rails控制台中看到CarrierWave类，并识别方法等，但我无法弄清楚如何打印我在应用程序中设置的配置变量。我查看了文档，并根据http://www.rubydoc.info/gems/carrierwave#Using_Amazon_S3设置了配置正常，但无法弄清楚如何在Rails控制台中显示配置设置。它将允许即时更改和测试。

This info would be useful for other gems too.

此信息对其他宝石也很有用。

Let's say that your uploader class is PhotoUploader

假设您的上传器类是PhotoUploader

in the console

在控制台中

PhotoUploader.fog_credentials

PhotoUploader.fog_credentials

PhotoUploader.fog_directory

PhotoUploader.fog_directory

and so on

等等

Or as instantiated object

或者作为实例化对象

u = PhotoUploader.new

你= PhotoUploader.new

u.fog_credentials

u.fog_credentials

u.fog_directory

u.fog_directory

These will print out the initialized configuration.

这些将打印出初始化配置。
