rails newの先輩オススメ手順
railsプロジェクトを新しく作成する際に実行する「rails new」のオススメ手順を、会社の先輩に教えていただいたのでメモ。
前提
手順
railsアプリケーション用のディレクトリを作成する。
→作成したディレクトリに移動
$ mkdir rails-app-name $ $ cd rails-app-name $ $ pwd /Users/maetoo11/workspace/rails-app-name $ $ ls -l $
railsアプリケーション用ディレクトリでbundle initを実行し、Gemfileを作成する。
$ ruby -v ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin15] $ $ bundle init Writing new Gemfile to /Users/maetoo11/workspace/rails-app-name/Gemfile $ $ $ $ ls -l total 8 -rw-r--r-- 1 maetoo11 staff 64 3 3 17:37 Gemfile
Gemfileを編集してrailsのgem を追加する。
$ vi Gemfile 1 source 'https://rubygems.org' 2 3 gem 'rails'
bundle installでGemfileで指定されたgemのインストールを行う。
ここで大事なこと！
--path vendor/bundleを指定し、railsアプリケーション用のディレクトリ配下のvendor/bundleディレクトリにgemをインストール
これにより、gemをrailsプロジェクト毎に管理できる！！--jobs=4を指定するとbundle installを並列処理で実行できる
参考：Bundlerで並列処理？？bundle installを爆速で処理する方法。 - Qiita

rails newを実行する際に、付与するオプションを決める。
→まずはヘルプを表示して、オプションを確認
$ bundle exec rails new -h
Usage:
rails new APP_PATH [options]
Options:
-r, [--ruby=PATH] # Path to the Ruby binary of your choice
# Default: /Users/maetoo11/.rbenv/versions/2.3.0/bin/ruby
-m, [--template=TEMPLATE] # Path to some application template (can be a filesystem path or URL)
[--skip-gemfile], [--no-skip-gemfile] # Don't create a Gemfile
-B, [--skip-bundle], [--no-skip-bundle] # Don't run bundle install
-G, [--skip-git], [--no-skip-git] # Skip .gitignore file
[--skip-keeps], [--no-skip-keeps] # Skip source control .keep files
-O, [--skip-active-record], [--no-skip-active-record] # Skip Active Record files
-S, [--skip-sprockets], [--no-skip-sprockets] # Skip Sprockets files
[--skip-spring], [--no-skip-spring] # Don't install Spring application preloader
-d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/oracle/postgresql/sqlite3/frontbase/ibm_db/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc)
# Default: sqlite3
-j, [--javascript=JAVASCRIPT] # Preconfigure for selected JavaScript library
# Default: jquery
-J, [--skip-javascript], [--no-skip-javascript] # Skip JavaScript files
[--dev], [--no-dev] # Setup the application with Gemfile pointing to your Rails checkout
[--edge], [--no-edge] # Setup the application with Gemfile pointing to Rails repository
[--skip-turbolinks], [--no-skip-turbolinks] # Skip turbolinks gem
-T, [--skip-test-unit], [--no-skip-test-unit] # Skip Test::Unit files
[--rc=RC] # Path to file containing extra configuration options for rails command
[--no-rc], [--no-no-rc] # Skip loading of extra configuration options from .railsrc file
Runtime options:
-f, [--force] # Overwrite files that already exist
-p, [--pretend], [--no-pretend] # Run but do not make any changes
-q, [--quiet], [--no-quiet] # Suppress status output
-s, [--skip], [--no-skip] # Skip files that already exist
Rails options:
-h, [--help], [--no-help] # Show this help message and quit
-v, [--version], [--no-version] # Show Rails version number and quit
Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time
'rails new' runs in the .railsrc configuration file in your home directory.
Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
今回は
- bundle installを飛ばす
- DBにMySQLを指定
- turbolinksを使用しない
- test-unitを使用しない
を指定してrails newを実行する。
2016/12/16 追記
Rails5からは
bundle exec rails new -B -d mysql --skip-turbolinks --skip-test.
らしいです。(未確認です)
$ bundle exec rails new -B -d mysql --skip-turbolinks --skip-test-unit .
exist
create README.rdoc
create Rakefile
create config.ru
create .gitignore
conflict Gemfile
Overwrite /Users/maetoo11/workspace/rails-app-name/Gemfile? (enter "h" for help) [Ynaqdh]
force Gemfile
create app

Gemfileを編集し、不要なgemの削除と必要なgemの追加を行う。
→今回は開発・テスト環境でwebrickではなくthinを使うようにした。(39行目)
$ vi Gemfile 1 source 'https://rubygems.org' 2 3 4 # Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 5 gem 'rails', '4.2.5.2' 6 # Use mysql as the database for Active Record 7 gem 'mysql2', '>= 0.3.13', '< 0.5' ・・・略・・・ 35 36 group :development do 37 # Access an IRB console on exception pages or by using <%= console %> in views 38 gem 'web-console', '~> 2.0' 39 gem 'thin' 40 41 # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring 42 gem 'spring' 43 end
vendor/bundle配下をgitで管理しないファイルにするために、.gitignoreを編集する。(9行目)
$ vi .gitignore 1 # See https://help.github.com/articles/ignoring-files for more about ignoring files. 2 # 3 # If you find yourself ignoring temporary files generated by your text editor 4 # or operating system, you probably want to add a global ignore instead: 5 # git config --global core.excludesfile '~/.gitignore_global' 6 7 # Ignore bundler config. 8 /.bundle 9 /vendor/bundle 10 11 # Ignore all logfiles and tempfiles. 12 /log/* 13 !/log/.keep 14 /tmp
bundlerの設定を確認する。
→最初のbundle install時に指定したオプションが設定されている。
→以降、このプロジェクトディレクトリで実行するbundlerはこの設定を使用する。
$ cat .bundle/config --- BUNDLE_PATH: vendor/bundle BUNDLE_JOBS: 4 BUNDLE_DISABLE_SHARED_GEMS: '1'
bundle installを実行する。
$ bundle Fetching gem metadata from https://rubygems.org/........... Fetching version metadata from https://rubygems.org/...

Post-install message from rdoc: Depending on your version of ruby, you may need to install ruby rdoc/ri data: <= 1.8.6 : unsupported = 1.8.7 : gem install rdoc-data; rdoc-data --install = 1.9.1 : gem install rdoc-data; rdoc-data --install >= 1.9.2 : nothing to do! Yay!
これでrails newのオススメ手順は終わりです。
