Rails的Heroku的无效配置选项

Question

当我部署到Heroku的和运行heroku run rake db:migrate我得到的错误：

ArgumentError: invalid configuration option `:aws_access_key_id' 

配置/初始化/ aws.rb

if Rails.env.production? 
    S3Client = Aws::S3::Client.new(
    aws_access_key_id: ENV['AWS_ACCESS_KEY_ID'], 
    aws_secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'], 
    aws_region: 'us-east-1' 
) 
end 

配置/初始化/ carrierwave.rb

if Rails.env.production? 
    CarrierWave.configure do |config| 
    config.fog_credentials = { 
     provider: 'AWS', 
     aws_access_key_id: ENV['AWS_ACCESS_KEY_ID'], 
     aws_secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'], 
     region: 'us-east-1' 
    } 
    config.fog_directory = ENV['S3_BUCKET'] 
    end 
end 

为什么我得到`invalid configuration option'错误？

编辑

新的配置/初始化/ carrierwave.rb文件：

if Rails.env.production? 
    CarrierWave.configure do |config| 
    config.fog_credentials = { 
     provider:    'AWS', 
     access_key_id:   ENV['AWS_ACCESS_KEY_ID'], 
     secret_access_key:  ENV['AWS_SECRET_ACCESS_KEY'], 
     region:     'us-east-1', 
     aws_access_key_id:  ENV['AWS_ACCESS_KEY_ID'], 
     aws_secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'], 
     aws_region:    'us-east-1' 
    } 
    config.fog_directory  = ENV['S3_BUCKET'] 
    #config.fog_attributes = {:signature_version => :v4} 
    end 
end 

配置/初始化/ aws.rb现在是空的。

这已修复了invalid configuration option问题。但是，当我运行RAILS_ENV=production bundle exec rake assets:precompile时，它被替换为错误Missing required arguments: aws_access_key_id, aws_secret_access_key。

更令人困惑的是，我在上述更改后成功运行了RAILS_ENV=production bundle exec rake assets:precompile，但它突然停止工作。

Answer 1

创建Aws::S3::Client时的选项不以aws_开头。那只会是愚蠢的。

if Rails.env.production? 
    S3Client = Aws::S3::Client.new(
    access_key_id: ENV['AWS_ACCESS_KEY_ID'], 
    secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'], 
    region: 'us-east-1' 
) 
end 

但是你实际上并不需要通过凭证选项：

Default credentials are loaded automatically from the following locations:

• ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']

• http://docs.aws.amazon.com/sdkforruby/api/Aws/S3/Client.html

我跟着从这个页面的步骤http://lifesforlearning.com/uploading-images-with-carrierwave-to-s3-on-rails/

代替PictureUploaded我用ImageUploader i n app/uploads/picture_uploader.rb，而不是carrier_wave.rb或carrierwave.rb我在s3.rb中设置了环境变量。它做了这些改变后为我工作。
