Question

我是Rails的新手，我正在使用Rails 3.2.0开发一个应用程序。因此，当我在我的本地机器上工作时，一切都很好，页面的设计需要以下方面：

  <head>
    <title>Ruby on Rails Tutorial Sample App</title>
    <link href="/assets/application.css?body=1" media="all" rel="stylesheet" type="text/css" />
<link href="/assets/custom.css?body=1" media="all" rel="stylesheet" type="text/css" />
<link href="/assets/static_pages.css?body=1" media="all" rel="stylesheet" type="text/css" />
<link href="/assets/users.css?body=1" media="all" rel="stylesheet" type="text/css" />
    <script src="/assets/jquery.js?body=1" type="text/javascript"></script>
<script src="/assets/jquery_ujs.js?body=1" type="text/javascript"></script>
<script src="/assets/static_pages.js?body=1" type="text/javascript"></script>
<script src="/assets/users.js?body=1" type="text/javascript"></script>
<script src="/assets/application.js?body=1" type="text/javascript"></script>
    <meta content="authenticity_token" name="csrf-param" />
<meta content="XWFSZcrp1zLXPwqKvANdCgQWr4ws6sM2xqylAYVprrQ=" name="csrf-token" />
    <!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
  </head>

然后我做了一个提交并将其推送到Heroku：

git push heroku

但我的网页没有必要的设计; Heroku的一些页面的负责人：

  <head>
    <title>Ruby on Rails Tutorial Sample App</title>
    <link href="/assets/application-7270767b2a9e9fff880aa5de378ca791.css" media="all" rel="stylesheet" type="text/css" />
    <script src="/assets/application-3428e82709d7645135002c8fadfafdc6.js" type="text/javascript"></script>
    <meta content="authenticity_token" name="csrf-param" />
<meta content="lSpfx/uG7gZoccxRHqdFBEQArAvQfI/EYXC/G/V79aU=" name="csrf-token" />
    <!--[if lt IE 9]>
<script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
  </head>

我不知道为什么但是“application -.... css”文件绝对干净！我该如何解决？我的production.rb：

SampleApp::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 = 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

  # Defaults to Rails.root.join("public/assets")
  # 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

  # Log the query plan for queries taking more than this (works
  # with SQLite, MySQL, and PostgreSQL)
  # config.active_record.auto_explain_threshold_in_seconds = 0.5
end

我应该改变什么？可能是production.rb中的一些设置必须修复？提前谢谢。

Heroku预编译application.css文件中的资源。您不应该在页面标题中指定各种css文件，这就是您正在做的事情。您需要确保它们位于包含application.css文件的文件夹中，并且您的application.css文件包含以下内容：

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the top of the
 * compiled file, but it's generally better to create a new file per style scope.
 *
 *= require_self
 *= require_tree .
 */

*= require_tree .行是重要的一行。它确保它获取文件夹中的所有css文件并加载它们。

资产不能在Heroku的一个文件中编译
