Last updated at Posted at 2017-06-16

最低限のコマンドとコードだけをまとめました。(2回目以降の導入に)

もう少し丁寧な導入方法はこちら
初めてのdevise ① -- 導入してみる --

環境

  • Ruby 2.3.3
  • Rails 4.1.16
  • Windows 8 64bit

作業

$ rails new devise
Gemfile
gem 'rails', '4.1.16'
gem 'sqlite3'
gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0',          group: :doc
gem 'tzinfo-data', platforms: [:mingw, :mswin, :x64_mingw]  #Win 32bitなら :x64_mingwは不要。
gem 'bcrypt-ruby', '~> 3.0.0'          # ←いれないとcannot load such file -- bcrypt_extが発生します。

#↓↓↓以下を追記します↓↓↓
gem 'devise'

$ bundle install
$ rails g devise:install
$ rails g devise User
$ rake db:migrate
$ rails g controller home index
application.html.erb.
<!DOCTYPE html>
<html>
<head>
  <title>Devise</title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>
</head>
<body>

  <!-- ↓↓↓これを追記↓↓↓ -->

    <%= link_to "新規作成", new_user_registration_path %>
