使用CDN资产管道的新阶段Rails资产路径不正确

Question

我有一个使用S3存储桶存储预编译资产的rails应用程序。这对于生产阶段非常有用。

我已经创建了一个名为'staging'的新阶段，它与生产阶段相同。我已经复制了S3存储桶并给出了不同的名称。

但是，当我使用临时环境部署我的rails应用程序时，应用资产路径设置为生产阶段路径。

如何获取分期资产以指向陈述资产路径？

这里是我的配置/环境/ 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

# Ignore bad email addresses and do not raise email 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"}

end 

任何帮助将不胜感激。

这是一个很长的镜头，但是您是否在托管网站的提供商在“生产”模式下运行网站？例如，如果您使用的是Heroku，即使您有单独的登台应用程序，一切都是“生产”。
