TodoList: ユーザ認証の設定: uyota 匠の一手

前回はプラグインをインストールしただけで、終わってしまった。今回は、user_engine の設定。

module LoginEngine
  config :salt, "your-salt-here"
  config :user_email_notification, false
end

module UserEngine
  config :admin_login, "uyota"
  config :admin_email, "uyota@example.com"
  config :admin_password, "XXXXX"
end

Engines.start :login
Engines.start :user

を config/environment.rb の末尾に追加。

app/controllers/application.rb を以下のように編集。

# Filters added to this controller will be run for all controllers in the application.
# Likewise, all the methods added will be available for all controllers.

require 'login_engine'

class ApplicationController < ActionController::Base
  include LoginEngine
  include UserEngine
  helper :user
  model :user
  #before_filter :login_required
  before_filter :authorize_action
  end
end

その後、app/helpers/application_helper.rb を以下のように編集。

module ApplicationHelper
  include LoginEngine
  include UserEngine
end

データベースを作るスクリプトと Makefile を作成。最初に make のターゲットを db にしたら、動かなかった。Rails が db というディレクトリを作っていたためだ。

% cat create_table.mysql 
DROP DATABASE todos;
CREATE DATABASE todos DEFAULT CHARACTER SET UTF8;
USE todos;
CREATE TABLE `todos`
(
  `id` INT NOT NULL AUTO_INCREMENT,
  `description` VARCHAR(100) NOT NULL,
  `done` TINYINT DEFAULT '0' NOT NULL,
  PRIMARY KEY(`id`)
);
% cat Makefile 
MYSQL = mysql -u root

database:
        cat create_table.mysql | ${MYSQL}
        rake db:migrate:engines:login_engine
        rake db:migrate:engines:user_engine
        rake bootstrap

make database で一気に必要なデータベースを作る。

% make
cat create_table.mysql | mysql -u root
rake db:migrate:engines:login_engine
(in /export/home/uyota/Todo)

rake bootstrap

Creating guest role 'Guest'
Creating admin role 'Admin'
Creating user role 'User'
Creating admin user 'uyota'

これで、http://localhost:3000/todo/list にアクセスすると http://localhost:3000/user/login に一度転送される。認証に成功すると、http://localhost:3000/todo/list に戻ってくる。

前回。次回。
