我的工作能够使用Capistrano的部署到生产环境。我面临着一些问题，同时修复其中大部分我们还有最后一个。

I worked on being able to deploy to production using capistrano. I face several issues and while fixing most of them we still have a last one.

我们的precompile资产选项不正确编译他们的生产，正因为如此，我们无法用过去的发展特点，因为他们在很大程度上依赖于JS。

Our precompile assets options are not properly compiling them on production and because of that, we are unable to use the last developed features as they rely heavily on JS.

但不尝试就如何会有人分析这个问题的影响，这是一些什么，我也试图使其工作：

Without trying to influence on how anyone would analyze this problem, this is some of what I did trying to make it work:

precompiled在当地的资产，推到GitHub库，帽部署，从本地计算机到EC2。帽部署是本地的，code被推到EC2是一个在github上。 在使用的建议Capistrano的任务试过。使用在Capfile负荷deploy'assets，让帽部署：安装任务做它的事 使用此选项帽部署：资产：干净，然后盖上部署：资产：precompile 在试图从公共除去资产，然后用pipeline_ precompile任务deploy.rb 过期的资产，迫使轨precompile一切都改变assets.versions在application.rb中 在环境中尝试不同的组合上config.assets / production.rb 最后，试图删除的生产和precompiling那里使用RAILS_ENV =产品包的exec耙资产公开/资产：precompile

该应用程序是不使用新的JS文件。如果您检查code无论是在回购或在服务器本身，我介绍了一个简单的点评到name.js.coffee（＃显示和隐藏依赖于在数据库中的数据菜单上线XXX），这是不是在生产中的编译assets.js。这是一个快速的测试，以确保近期的资产正在被使用。

The app is just not using the new JS files. If you check the code either on the repo or in the server itself, I introduced a simple comment to the name.js.coffee ("# Shows and hides menus depending on the data on DB" on line xxx) and this is not in the compiled assets.js in production. This is a quick test to be sure the recent assets are being used.

这里的整个问题是js和css文件，没有那么多轨道。这就是为什么它是如此难以测试或发现..这样的原因JS框架的普及近来之一。如果有问题，你不必杀死自己寻找问题的所在。如果该概率是红宝石或导轨，一般不会花这么长时间来了解一下。一旦到了JS，CSS和跨浏览器兼容，那么，这是手头的问题。

The whole problem here is the js and css files, not so much rails. Which is why it is so difficult to test or find.. Thus one of the reasons for the popularity of js frameworks lately. In case of problems, you don't have to kill yourself looking for where the problem is.. If the prob is in ruby or rails, usually doesn't take that long to find out. Once you get to js, css and cross browser compatibility, well, this IS the problem at hand.

和./Capfile：

And ./Capfile:

load 'deploy'
# Uncomment if you are using Rails' asset pipeline
load 'deploy/assets'
load 'config/deploy' # remove this line to skip loading any of the default tasks
