我遇到了這個錯誤

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

圖像上傳工作在localhost上完美無瑕。我不是爲什麼它在Heroku上給出這個錯誤。我檢查了credentail config環境變量，它們是正確的。它們沒有問題。即使使用了heroku日誌，沒有其他任何事情可以推斷出來，而不是狀態：500。有人可以幫助我得到完整的錯誤消息，因爲知道錯誤的Heroku日誌或讓我知道上面的代碼有什麼問題。提前感謝lott

Answer 1

以下是Heroku應用程序的一些有用的調試設置。

在production.rb：

# More meaningful logs 
config.log_level = :debug 

# More meaningful error pages 
config.consider_all_requests_local = true 

Answer 2

我想通了錯誤設置：

Production.rb

# More meaningful logs 
config.log_level = :debug 

# More meaningful error pages 
config.consider_all_requests_local = true 

在我的情況不存在與問題：s3_region，我固定它通過配置ENV變量爲heroku

heroku config:set AWS_REGION=us-east-1
