在 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。这非常适合制作阶段。

我创建了一个名为“staging”的新阶段，它与生产阶段相同。我复制了 S3 存储桶并为其命名。

但是，当我使用暂存环境部署我的 rails 应用程序时，应用程序资产路径设置为生产阶段路径。

如何让暂存资产指向声明资产路径？

这是我的 config/environments/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

这是一个长镜头，但是您托管该网站的提供商可以在“生产”模式下运行该网站吗？例如，如果您使用 Heroku，即使您有一个单独的临时应用程序，一切都是“生产”的。
