herokuでgithubで管理しているRails3.2アプリを動かすまで

準備

Railsプロジェクトをgitで管理するまでやる。

まずRailsプロジェクトを作成今回はsfmailerという名前のプロジェクトにする

$ rails -v 
Rails 3.2.3
$ rails new sfmailer

gitで管理するようにして最初のコミットをする

$ cd sfmailer
$ git init
Initialized empty Git repository in /home/toyoshi/projects/sfmailer/.git/
$ git add .
$ git commit -m "first commit"

githubを使う

githubにリポジトリを作り、pushできるようにするまで。

リポジトリを作ります

名前を適当に決めて完了

これでgithubにリポジトリができたので、さっき作ったローカルのファイル郡をpushしてみます

$ git remote add origin git@github.com:toyoshi/form_mailer_generator.git
$ git push -u origin master
Counting objects: 63, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (49/49), done.
Writing objects: 100% (63/63), 25.96 KiB, done.
Total 63 (delta 2), reused 0 (delta 0)
To git@github.com:toyoshi/form_mailer_generator.git
 * [new branch]      master -> master
Branch master set up to track remote branch master from origin.

ファイルが追加されて無事コミットされたようです

herokuの準備

herokuのgemをインストールするのでGemfileを編集してbundle install

gem 'heroku', :group => [:development]

するとherokuコマンドが使えるようになるのでherokuにアプリを登録

$ heroku create
Creating severe-leaf-5323..................... done, stack is bamboo-mri-1.9.2
http://severe-leaf-5323.heroku.com/ | git@heroku.com:severe-leaf-5323.git
Git remote heroku added

http://severe-leaf-5323.heroku.com/にアクセスして確認してみます

さらに.git/configをみてみると"heroku"というリモートリポジトリが登録されています

$ cat .git/config 
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = git@github.com:toyoshi/form_mailer_generator.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
        remote = origin
        merge = refs/heads/master
[remote "heroku"]
        url = git@heroku.com:severe-leaf-5323.git
        fetch = +refs/heads/*:refs/remotes/heroku/*

さっそくpushしてみましょう

$ git push heroku master
Counting objects: 63, done.
Delta compression using up to 2 threads.
Compressing objects: 100% (49/49), done.
Writing objects: 100% (63/63), 25.96 KiB, done.
Total 63 (delta 2), reused 0 (delta 0)

おまけ

hamlとrspecを最初からいれておく

gem 'haml-rails'

group :test, :development do
  gem "rspec-rails", "~> 2.6"
end
