[ ] 모든것은 프로젝트 폴더내에서

D:\web>cd phonebook

 

[ ] 자기 입맞에 맞게 편집 : 안해도 됨.

D:\web\phonebook\config/database.yml

development:
  adapter: mysql
  encoding: utf8
  database: phonebook
  username: root
  password:
  host: localhost

 

[ ] Database만 생성 (3개 생성하쥐)

D:\web\phonebook>rake db:create:all
(in D:/web/phonebook)

 

[ ] people이라는 모델을 중심으로한 모든 scaffold 코드 생성

D:\web\phonebook>ruby script/generate scaffold People name:string phone_number:string note:text

      create  app/helpers/peoples_helper.rb
       route  map.resources :peoples

 

[ ] 001_create_peoples.rb를 기준으로 Table생성

D:\web\phonebook>rake db:migrate
(in D:/web/phonebook)
== 1 CreatePeoples: migrating =================================================
-- create_table(:peoples)
   -> 0.3590s
== 1 CreatePeoples: migrated (0.3590s) ========================================

[ ] 002_create_groups.rb 편집

class CreateGroups < ActiveRecord::Migration
  def self.up
    create_table :groups do |t|
      t.string :name

      t.timestamps
    end
   
    add_column :peoples, :group_id, :integer
  end

  def self.down
    remove_column :peoples, :group_id
    drop_table :groups
  end
end

 

[ ] 스키마 변경사항 반영

D:\web\phonebook>rake db:migrate
(in D:/web/phonebook)
== 2 CreateGroups: migrating ==================================================
-- create_table(:groups)
   -> 0.0000s
-- add_column(:peoples, :group_id, :integer)
   -> 0.0150s
== 2 CreateGroups: migrated (0.0150s) =========================================

 

[ ] 모델 연관관계 설정

class People < ActiveRecord::Base
  belongs_to :group
end

 

class Group < ActiveRecord::Base
  has_many :people
end

 

[ ] people 컨트롤러 수정

  def new
    @people = People.new
    @groups = Group.find(:all)
  end

  def edit
    @people = People.find(params[:id])
    @groups = Group.find(:all)
  end

[ ] view수정

index.html.erb

<th>그룹</th>

<td><%=h people.group.name %></td>

 

show.html.erb

<p>
  <b>그룹:</b>
  <%=h @people.group.name %>
</p>

 

new.html.erb

  <p>
    <b>그룹</b><br />
    <%= f.select("group_id", @groups.map {|g| [g.name, g.id]}) %>
  </p>

 

edit.html.erb

  <p>
    <b>그룹</b><br />
    <%= f.select("group_id", @groups.map {|g| [g.name, g.id]}) %>
  </p>

 

[ ] helper 코드로 변환된 html소스중 눈여겨 보아야 할것.
