Rails: user_engine の試用: uyota 匠の一手

user_engine を設定する上での覚書。user_engine を使うためのプラグインをインストール。

% rails test
...
% cd test
% ruby script/plugin install engines
...
+ ./engines/tasks/deprecated_engines.rake
+ ./engines/tasks/engines.rake
+ ./engines/test/action_view_extensions_test.rb
+ ./engines/test/ruby_extensions_test.rb
% ruby script/plugin install login_engine
...
+ ./login_engine/test/mocks/mail.rb
+ ./login_engine/test/mocks/time.rb
+ ./login_engine/test/test_helper.rb
+ ./login_engine/test/unit/user_test.rb
% ruby script/plugin install user_engine
...
+ ./user_engine/README
+ ./user_engine/app/controllers/permission_controller.rb
+ ./user_engine/app/controllers/role_controller.rb

user_engine を使うための設定。いくつかのファイルは編集が必要。メールでの通知は一時停止した。config/environment.rb は末尾に以下を追加。

% cat >> config/environment.rb
module LoginEngine
  config :salt, "your-salt-here"
  config :user_email_notification, false
end

Engines.start :login
Engines.start :user

更にいくつかの変更。app/controllers/application.rb と app/helpers/application_helper.rb はほとんど空だった。

% cat > app/controllers/application.rb
# Filters added to this controller will be run for all controllers in the applic
ation.
# 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
^D
% cat > app/helpers/application_helper.rb
# Methods added to this helper will be available to all templates in the applica
tion.
module ApplicationHelper
  include LoginEngine
  include UserEngine
end
^D

config/environment.rb に管理者の設定を追加。

% vi config/environment.rb
module UserEngine
   config :admin_login, "the login name for your administrator user"
   config :admin_email, "an email address for your administrator"
   config :admin_password, "your initial admin password"
end

データベースを作成。ここでテーブルに必要事項が追加される。デフォルトでは users で、テーブルは空でなければいけないそうだ。

% rake db:migrate:engines:user_engine
(in /export/home/uyota/test)

script/server で起動し http://localhost:3000/user/login にアクセス。成功していれば、ログイン画面が出てくる。

前回。次回。
