Heroku ArgumentError（不是公認的提供商）

Question

我正嘗試使用回形針和霧寶石將個人資料圖片上傳到Google Cloud。到目前爲止，這是我有

在我的Gemfile

gem "paperclip", git: "git://github.com/thoughtbot/paperclip.git" 
gem 'fog' 

在我的用戶模型

has_attached_file :avatar, 
         styles: {:big => "200x200>", thumb: "50x50>"}, 
         storage: :fog, 
         fog_credentials: "#{Rails.root}/config/gce.yml", 
         fog_directory: "google-bucket-name" 

    validates_attachment_content_type :avatar, content_type: /\Aimage\/.*\Z/ 

當我運行這個地方，我可以把它上傳罰款交給谷歌。但是，當我嘗試在Heroku上執行此操作時，出現此錯誤

不知道發生了什麼事。

Answer 1

經過大量的調試，結果我的fog_credentials散列未按預期在heroku上。而不是通過「＃{Rails.root} /config/gce.yml」，我這樣做。

has_attached_file :avatar, 
         styles: {:big => "200x200>", thumb: "50x50>"}, 
         storage: :fog, 
         fog_credentials: { aws_access_key_id: '<your_access_id>' 
             aws_secret_access_key: '<your secret>' 
             provider: 'Google' }, 
         fog_directory: "google-bucket-name" 

    validates_attachment_content_type :avatar, content_type: /\Aimage\/.*\Z/
