Rails 3应用程序，如何获得GIT版本和更新网站？ [英] Rails 3 app, How to get GIT version and update website?

问题描述

我正在使用capistrano部署我的rails 3应用程序，并且我想要获取git版本（和日期信息）并更新我的网站页脚。

我可以这样做吗？

解决方案

基于David的指导，我通过创建初始化程序git_info.rb解决了这个问题。将这个文件放在你的Rails初始化器目录中。

git_info.rb的内容是：

pre> GIT_BRANCH =`git status | sed -n 1p`.split（）.last
GIT_COMMIT =`git log | sed -n 1p`.split（）.last


然后在您的页脚中，您可以使用这个输出（HAML语法）：

  #rev_info 
 =分支：＃{GIT_BRANCH} | commit：＃{ GIT_COMMIT}
  

您可能希望将#rev_info的字体颜色设置为与背景颜色相同，所以文本只有在用光标突出显示时才是可见的。

我刚刚尝试了这一点，并且在开发模式下工作时，用部署post capistrano部署编写。 Capistrano必须在部署时创建自己的本地分支，称为部署？

I am deploying my rails 3 app using capistrano, and I want to get the git version (and date information) and update my website's footer with this.

How can I do this?

解决方案

Based on David's direction, I solved this by creating an initializer "git_info.rb". Place this file in your Rails initializers directory

The contents of the git_info.rb are:

GIT_BRANCH = `git status | sed -n 1p`.split(" ").last
GIT_COMMIT = `git log | sed -n 1p`.split(" ").last

Then in your footer, you can use this output (HAML syntax):

#rev_info
  = "branch: #{GIT_BRANCH} | commit: #{GIT_COMMIT}"

You may want to set the font color of #rev_info the same as the background color, so the text is visible only when you highlight it with your cursor.

I just tried this, and while it works in development mode, it seems like the branch gets over-written with "deploy" post capistrano deploy. Capistrano must be creating it's own local branch called "deploy" on deploy?
