我在 Heroku 上托管了一个 LocomotiveCMS 应用程序。此后我一直直接在 Heroku MongoHQ 数据库上工作，并完成了 wesbite。

然后，我在本地机器上设置了开发数据库以连接到 HerokuApp 使用的 MongoHQ 数据库，因此本地机器使用网络上的实际数据。但是资产（CSS 和 JS 文件）无法正确访问。即使我已经设置了 AWS 凭证。

因此，当我在本地机器上访问 CSSS+JS 文件时，我得到了这些文件，但没有内容，即空白文件。正如我在 Heroku 服务器上看到的那样，我也没有获得资产的 AWS 链接。

是否与资产预编译有关。我已经完全按照这里的描述设置了 Heroku：http: //doc.locomotivecms.com/guides/hosting/heroku-hosting

production.rb 文件如下：

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

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

  # Full error reports are disabled and caching is turned on
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true

  # Disable Rails's static asset server (Apache or nginx will already do this)
  config.serve_static_assets = false

  # Compress JavaScripts and CSS
  config.assets.compress = true

  # Don't fallback to assets pipeline if a precompiled asset is missed
  config.assets.compile = false

  # Generate digests for assets URLs
  config.assets.digest = true

  # Defaults to nil and saved in location specified by config.assets.prefix
  # config.assets.manifest = YOUR_PATH

  # Specifies the header that your server uses for sending files
  # config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
  # config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx

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

  # See everything in the log (default is :info)
  # config.log_level = :debug

  # Prepend all log lines with the following tags
  # config.log_tags = [ :subdomain, :uuid ]

  # Use a different logger for distributed setups
  # config.logger = ActiveSupport::TaggedLogging.new(SyslogLogger.new)

  # 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"

  # Precompile additional assets (application.js, application.css, and all non-JS/CSS are already added)
  # config.assets.precompile += %w( search.js )

  # Disable delivery errors, bad email addresses will be ignored
  # config.action_mailer.raise_delivery_errors = false

  # Enable threaded mode
  # config.threadsafe!

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

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

    config.action_mailer.delivery_method = :smtp
    config.action_mailer.smtp_settings = {
      :address        => 'smtp.sendgrid.net',
      :port           => 25,
      :authentication => :plain,
      :user_name      => ENV['SENDGRID_USERNAME'],
      :password       => ENV['SENDGRID_PASSWORD'],
      :domain         => ENV['SENDGRID_DOMAIN']
    }

end

在您的控制台中运行它

bundle exec rake assets:precompile

然后推送到 git，然后推送到 heroku

我理解为什么您将以下设置设置为config.assets.initialize_on_precompile = false使您的应用程序运行得更快。然而，ruby on rails 指南指出以下内容：

如果您将 config.assets.initialize_on_precompile 设置为 false，请务必在部署之前在本地测试 rake assets:precompile。它可能会暴露您的资产引用应用程序对象或方法的错误，因为无论此标志的值如何，这些仍然在开发模式的范围内。

因此，这可能是您问题的根源。此外，如果您想包含其他内容css，js您可以将以下内容添加到预编译数组中，如下所示：

config.assets.precompile += ['admin.js', 'admin.css']

希望这可以帮助
