使用CDN資產管道的新階段Rails資產路徑不正確

Question

我有一個使用S3存儲桶存儲預編譯資產的rails應用程序。這對於生產階段非常有用。

我已經創建了一個名爲'staging'的新階段，它與生產階段相同。我已經複製了S3存儲桶並給出了不同的名稱。

但是，當我使用臨時環境部署我的rails應用程序時，應用資產路徑設置爲生產階段路徑。

如何獲取分期資產以指向陳述資產路徑？

這裏是我的配置/環境/ staging.rb

Rails.application.configure do 
# Settings specified here will take precedence over those in config/application.rb. 

# Read from yml file 
config.before_configuration do 
    env_file = File.join(Rails.root, 'config', 'local_env.yml') 
    YAML.load(File.open(env_file)).each do |key, value| 
    ENV[key.to_s] = value 
    end if File.exists?(env_file) 
end 

# Code is not reloaded between requests. 
config.cache_classes = true

# your application in memory, allowing both threaded web servers

# Rake tasks automatically ignore this option for performance.

# config.action_dispatch.rack_cache = true

# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies. 
# config.force_ssl = true 

# Use the lowest log level to ensure availability of diagnostic information

# Use a different logger for distributed setups.

# Use a different cache store in production. 
# config.cache_store = :mem_cache_store 

# Enable serving of images, stylesheets, and JavaScripts from an asset server. 
# config.action_controller.asset_host = 'http://assets.example.com' 
ENV["AWS_ASSET_DIRECTORY"] = 'website-assets-staging' 
config.action_controller.asset_host = "//#{ENV["AWS_ASSET_DIRECTORY"]}.s3.amazonaws.com" 

# Ignore bad email addresses and do not raise email delivery errors. 
# Set this to true and configure the email server for immediate delivery to raise delivery errors. 
# config.action_mailer.raise_delivery_errors = false 

# Enable locale fallbacks for I18n (makes lookups for any locale fall back to 
# the I18n.default_locale when a translation cannot be found). 
config.i18n.fallbacks = true 

# Send deprecation notices to registered listeners. 
config.active_support.deprecation = :notify 

# Use default logging formatter so that PID and timestamp are not suppressed. 
config.log_formatter = ::Logger::Formatter.new 

# Do not dump schema after migrations. 
config.active_record.dump_schema_after_migration = false 

config.action_mailer.default_url_options = {:host => "staging.website.com.au"} 
config.action_mailer.delivery_method = :smtp 
end 

任何幫助將不勝感激。

這是一個很長的鏡頭，但是您是否在託管網站的提供商在「生產」模式下運行網站？例如，如果您使用的是Heroku，即使您有單獨的登臺應用程序，一切都是「生產」。
