如何使用git复制rails应用程序并将其部署到heroku [英] How to copy rails app using git and deployed to heroku

问题描述

我是编程和rails的新手，我想创建一个我正在使用的rails应用程序的副本，以便无害地尝试一些事情。有没有一种简单的方法来实现这一点？

解决方案

是的，你可以。这些命令对于像我这样的新手来说并不明显，并且可能会帮助其他人......

首先，根据您打算调用新部署的应用程序的计划，找到名称，目前在heroku上可用。

从旧的根目录创建新的rails应用程序：

  $ cp -R old_directory new_directory 
 $ cd new_directory 
 $ rm -rf .git 
＃查找并替换new_directory中找到的old_director的所有引用
＃在终端'grep -riold_director。'中的命令可以帮助找到
＃对old_directory 
 $ git init 
 $ git add的所有引用。 
 $ git ci -am从old_app复制后首次提交
＃在github上创建new_directory存储库。通过适当修改，沿着他们的
＃指示新的存储库。 
 $ git remote add origin [e-mail]：[github username] / [new_directory] ​​.git 
 $ git push -u origin master 
 $ rake db：migrate 
 $ heroku create [new_app] 
 $ git push heroku master 
  

生成一个新的密钥您的新应用程序：

$ $ p $ code $ rake secret＃为新应用程序生成新密钥

接下来，使用以下命令将新创建的密钥保存为Heroku上的环境变量：

  $ heroku上配置：设置SECRET_KEY_BASE = 5ed8c7d9a3bda9cec3887b61f22aa95bf430a3a550407642b96751c7ef0ce8946a161506d6739da0dcaaea8c8f4f8b3335b1fb549e3cc54f0a4cec554ede05f8 
  

有关将密钥等存储为环境变量的更多详细信息，请参见 Daniel Fone的博客。

最后：

  $ heroku运行rake db：migrate 
  

I'm new to programing and rails and I'd like to create a copy of a rails app I'm working with to harmlessly try out some things. Is there an easy way to make that happen?

解决方案

Yes you can. These commands weren't obvious to a newbie like me and may help someone else...

First, depending on what you plan on calling your new deployed app, find a name that is currently available on heroku.

From root of old and to be created new rails app:

$ cp -R old_directory new_directory
$ cd new_directory
$ rm -rf .git
# find and replace all references to old_director found within new_directory
# the command at the terminal 'grep -ri "old_director" .' may help to locate 
# all of the references to the old_directory
$ git init
$ git add .
$ git ci -am "First commit after copying from old_app"
# create new_directory repository at github.  Follow along their 
# directions for new repository with appropriate modifications.  
$ git remote add origin [e-mail]:[github username]/[new_directory].git
$ git push -u origin master
$ rake db:migrate
$ heroku create [new_app]
$ git push heroku master

To generate a new secret key for your new app:

$ rake secret  # generate new secret key for new app
5ed8c7d9a3bda9cec3887b61f22aa95bf430a3a550407642b96751c7ef0ce8946a161506d6739da0dcaaea8c8f4f8b3335b1fb549e3cc54f0a4cec554ede05f8

Next, save the newly created secret key as an environmental variable on Heroku with the following command:

$ heroku config:set SECRET_KEY_BASE=5ed8c7d9a3bda9cec3887b61f22aa95bf430a3a550407642b96751c7ef0ce8946a161506d6739da0dcaaea8c8f4f8b3335b1fb549e3cc54f0a4cec554ede05f8

More details about storing secret keys, etc., as environmental variables can be found on Daniel Fone's Blog.

Finally:

$ heroku run rake db:migrate
