(Note svn must be in path) -g, --git Modify files with git. (Note git must be in path) Description Scaffolds an entire resource, from model and migration to controller and views, along with a full test suite. The resource is ready to use as a starting point for your RESTful, resource-oriented application. Pass the name of the model (in singular form), either CamelCased or under_scored, as the first argument, and an optional list of attribute pairs. Attribute pairs are column_name sql_type arguments specifying the model s attributes. Timestamps are added by default, so you don t have to specify them by hand as created_at datetime updated_at datetime . You don t have to think up every attribute up front, but it helps to sketch out a few so you can start working with the resource immediately. For example, scaffold post title string body text published boolean gives you a model with those three attributes, a controller that handles the create/show/update/destroy, forms to create and edit your posts, and an index that lists them all, as well as a map.resources posts declaration in config/routes.rb. If you want to remove all the generated files, run script/destroy scaffold ModelName .

のうはう色々 メール送信のうはう やりたいこと メールをiso2022jpで送信したい。 SenderID/SPFなどに対応するために各ヘッダーを変更したい。特にreturn-path 考え方と現状 基本ActionMailerをベースにする ActionMailerではメールボディの文字コード変換まではサポートされている。でもsubjectやfromに日本語が入ると化ける ActionMailerを拡張したIso2022jpMailerというライブラリがActiveHeartプラグインに付属するが、subjectを変換してなれないなど、いま一歩感が残る。 プラグインなどで「これが一般的!」というのは無い? みんなIso2022jpMailerベースで必要なところだけ文字コード変換して使ってるのかな? だとするなら、ActionMailerのdeliver*メソッドで必要部分だけNKFなどで変換すれば、別途プラグインを使う必要はないのでは? bodyの変換機能はデフォルトで付いてるし。 てかそれってDRYの原則に反してるよね。 結局何がベスト? config/environment.rbの最後に ActionMailer Base.sendmail_settings = { location = /usr/sbin/sendmail , arguments = -i -t -f from.mailaddress@example.com } ActionMailer Base.delivery_method = sendmail #ActionMailer Base.delivery_method = smtp ActionMailer Base.raise_delivery_errors = true ActionMailer Base.default_charset = iso-2022-jp を追加。sendmailの-fオプションで送信元メールアドレスとreturn-pathに使うアドレスを指定。 モデルはこんな感じ。コントローラーからdeliver_to_logined_user(object, user)で呼ぶ。 class Notifier Iso2022jpMailer def to_logined_user( object, user ) # Email header info MUST be added here recipients user.mail_address from "from.address.for.header@example.com" # 必要なところでiso2022jp変換+base64エンコードする subject "[static message]" + base64("日本語にほんご") # うまく使えないけど、ヘッダーに文字は入る # headers "¥r¥nReturn-Path" = "return-path.address.for.header@exapmle.com" # Email body substitutions go here body object_for_view = object, user_for_view = user end def base64(text, charset="iso-2022-jp", convert=true) if convert if charset == "iso-2022-jp" text = NKF.nkf( -j -m0 , text) end end text = [text].pack( m ).delete("\r\n") "=?#{charset}?B?#{text}?=" end end このbase64メソッドを標準でどこかのプラグインに入れておけば良いのかなぁ。 日本語解説ページ 優しいRailsの育て方|Action Mailer Nasuta開発ブログ|メール配信の実装 Railsアプリケーションからメール送信（Iso2022jpMailer） 日本語処理のうはう Rubyでの日本語文字列処理 デプロイのうはう masuidrive on rails|「設定より規約」でWebサーバ設定の自動化 ※増井さんのスクリプト興味あるなぁ Ajax系のうはう ここらへん読むとRailsとjson-pの絡ませ方がわかる気がする JSON-P on Rails with JQuery Cross domain RESTful JSON-P with Rails コメント 名前
