在开发机器上设置生产服务器，以便使用rails 3资产管道。

Question

在我的生产模式下运行的本地机器上(例如，rails s -e production)，我使用RAILS_ENV=production bundle exec rake assets:precompile生成了css，它创建了application-d2bcfd35ef1c0c30b7a7ca94e52c0cbd.css，布局文件也引用了这个application-d2bcfd35ef1c0c30b7a7ca94e52c0cbd.css。

然而，在加载页面时，我得到了错误：

Started GET "/assets/application-d2bcfd35ef1c0c30b7a7ca94e52c0cbd.css" for 127.0.0.1 at 2011-11-02 10:12:55 +0000

我阅读了配置rails指南：

• config.serve_static_assets将Rails本身配置为服务于静态资产。默认为true，但在生产环境中关闭，因为用于运行应用程序的服务器软件(例如，Nginx或Apache)应该提供静态资产。与默认设置不同，在运行时将其设置为true (绝对不推荐！)或者使用WEBrick在生产模式下测试应用程序。否则，您将无法使用页面缓存和请求的文件，经常存在的公共目录下，反正会击中您的Rails应用程序。

因此，将config.serve_static_assets更改为用于production.rb的true将正确引用文件。是否有一种方法可以配置webrick来服务资产管道文件？或者还有其他的rails服务器可以很容易地设置，让我的开发机器在生产模式下运行？

我在MacOS10.6(雪豹)上运行Apache web服务器。

Answer 1

您可以克隆流浪汉 (RailsCasts插曲)的生产环境，这将使开发机器上的生产环境测试更加逼真。

或

您可以创建测试生产设置的新环境，并将config.serve_static_assets标记为true。

或

您可以尝试使用其他服务器，如瘦的.

第一个可能会给你最精确的结果，它将如何工作在生产，你将不会使用Webrick或薄的生产。
