ruby-on-rails - Rails 应用程序未在生产环境中使用预编译 Assets

Question

我有一个 Rails 应用程序，可以很好地加载开发中的所有 Assets 。

<link rel="stylesheet" href="/assets/reset.css" type="text/css" media="screen" title="no title" />
<link rel="stylesheet" href="/assets/text.css" type="text/css" media="screen" title="no title" />
<link rel="stylesheet" href="/assets/buttons.css" type="text/css" media="screen" title="no title" />
<link rel="stylesheet" href="/assets/theme-default.css" type="text/css" media="screen" title="no title" />
<link rel="stylesheet" href="/assets/login.css" type="text/css" media="screen" title="no title" />
<link rel="stylesheet" href="/assets/notify.css" type="text/css" media="screen" title="no title" />

而在生产服务器上，它仍然使用上面的代码来加载 CSS。它不应该改用/assets/applicaiton.css 文件吗？我已经在生产环境中手动运行了 rake assets:precompile 任务，我可以看到它已经在/public/assets 文件夹中创建了所需的文件。

那么，我需要做什么来告诉 Rails 使用压缩文件？

我的 production.rb 看起来像这样:-

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

 # 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

Answer 1

你应该像这样使用 stylesheet_link_tag 助手来调用 css 文件:

= stylesheet_link_tag "application", :media => "all"

并将您的样式表插入到应用程序样式表文件中，例如:

= require reset
= require text
= require button
...

然后修改您的 production.rb 文件以将 config.assets.compile 设置为 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.compress = true

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

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