我遇到了这个错误

We're sorry, but something went wrong.
If you are the application owner check the logs for more information.

图像上传工作完全正常localhost.I不是为什么它在Heroku上给出了这个错误。我检查了credentail配置环境变量，它们是正确的。没有问题。即使使用heroku日志，也没有别的东西可以推断而不是状态：500。有人可以帮助我获取heroku日志的完整错误消息以了解错误或让我知道上面的代码有什么问题。 Thanx a lott提前

Answer 1

以下是Heroku应用程序的一些有用的调试设置。

在production.rb中：

# More meaningful logs
config.log_level = :debug

# More meaningful error pages
config.consider_all_requests_local = true

Answer 2

我通过设置确定错误：

Production.rb

# More meaningful logs
config.log_level = :debug

# More meaningful error pages
config.consider_all_requests_local = true

在我的情况下有问题：s3_region，我通过config ENV变量为heroku修复了

heroku config:set AWS_REGION=us-east-1

S3的回形针在Localhost上工作正常，但在Heroku上给出了错误
