Rails 应用程序在生产环境中不使用预编译资源

Question

我有一个Rails应用程序，可以很好地加载开发中的所有资产。

<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。它不应该使用/assets/applicaiton.css 文件吗？我已经在生产环境中手动运行了 rake assets：预编译任务，我可以看到它在/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使用压缩文件呢？

我的生产.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

你应该使用 stylesheet_link_tag 帮助程序像这样调用 css 文件：

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

并将样式表插入应用程序样式表文件中，例如：

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

然后修改你的 production.rb 文件，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
