安裝步驟

1. On your gemfile: gem 'rails_admin', '~> 1.0' #增加gem至gemfile
2. Run bundle install
3. Run rails g rails_admin:install
4. Provide a namespace for the routes when asked  
5. Start a server rails s and administer your data at /admin. (if you chose default namespace: /admin)

在使用者增加欄位 判斷是否為管理者 admin:boolean

  User Load (0.3ms)  SELECT  "users".* FROM "users" ORDER BY "users"."id" DESC LIMIT ?  [["LIMIT", 1]]

=> #<User id: 3, email: "1@gmail.com", created_at: "2016-10-04 03:01:32", updated_at: "2016-10-04 03:01:32", admin: nil>

irb(main):003:0> u.save
