Question

查看我的主页的来源：

  <link data-turbolinks-track="true" href="/assets/application-ea3565aaa6bc4c481fc9425308d6bd54.css" media="all" rel="stylesheet" />
  <script data-turbolinks-track="true" src="/assets/application-2192d37159557835f39e5f3914e03276.js"></script>

然后我从“隐身”窗口刷新......

  <link data-turbolinks-track="true" href="/stylesheets/application.css" media="all" rel="stylesheet" />
  <script data-turbolinks-track="true" src="/javascripts/application.js"></script>

然后我再次刷新。它恢复原状。

你可以想象，这种行为令人非常沮丧。

我正在使用Unicorn + nginx。摘录自config/environments/production.rb：

  config.cache_classes = true

  # Eager load code on boot. This eager loads most of Rails and
  # your application in memory, allowing both thread web servers
  # and those relying on copy on write to perform better.
  # Rake tasks automatically ignore this option for performance.
  config.eager_load = 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 = true

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier

  # Do not fallback to assets pipeline if a precompiled asset is missed.
  config.assets.compile = true

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

使用摘要生成资产的curl标头：

Answer 1

当设置缓存的某个地方时会发生这种情况，因此：

重新检查环境，应将其设置为production
在cache

app/views/layouts/application.html

从远程服务器上的旧缓存文件中清除目录your_app/public/assets

然后重新部署

有时（不可预测）我的Rails应用程序通过摘要服务我的资产。有时，没有
