Rails 2.0とFlex 3 beta3でRESTfulなBookmarkアプリを作ろう 1

使うもの

• サーバサイド: Rails 2.0.1
• DB: sqlite3
• IO: REST
• クライアントサイド: Flex 3 beta3

準備

>gem install rails
>gem install sqlite3-ruby

とかやればいいでしょう。

Railsアプリをコマンドラインで作成

実行したコマンドだけまとめると

>rails -d sqlite3 rails2restful
>cd rails2restful
>rake db:create
>ruby script\generate scaffold bookmark name:string url:string
>rake db:migrate

サーバ起動

D:\rails\rails2restful>ruby script\server
=> Booting WEBrick...
=> Rails application started on http://0.0.0.0:3000
=> Ctrl-C to shutdown server; call with --help for options

ブラウザで動作確認

http://localhost:3000/bookmarks/を開く

Bookmarkを追加してみる

• REDHANDS http://redhands.jp/
• 東急ハンズ http://www.tokyu-hands.co.jp/

RESTで見る

http://localhost:3000/bookmarks.xmlを開く

<?xml version="1.0" encoding="UTF-8"?>
<bookmarks type="array">

  <bookmark>
    <created-at type="datetime">2007-12-17T06:41:23+09:00</created-at>
    <id type="integer">1</id>
    <name>REDHANDS</name>

    <updated-at type="datetime">2007-12-17T06:41:23+09:00</updated-at>
    <url>http://redhands.jp/</url>
  </bookmark>
  <bookmark>
    <created-at type="datetime">2007-12-17T06:41:45+09:00</created-at>

    <id type="integer">2</id>
    <name>&#26481;&#24613;&#12495;&#12531;&#12474;</name>
    <updated-at type="datetime">2007-12-17T06:41:45+09:00</updated-at>

    <url>http://www.tokyu-hands.co.jp/</url>
  </bookmark>
</bookmarks>

よしよし。

では http://localhost:3000/bookmarks/1.xmlを開くと

<?xml version="1.0" encoding="UTF-8"?>
<bookmark>
  <created-at type="datetime">2007-12-17T06:41:23+09:00</created-at>
  <id type="integer">1</id>
  <name>REDHANDS</name>

  <updated-at type="datetime">2007-12-17T06:41:23+09:00</updated-at>
  <url>http://redhands.jp/</url>
</bookmark>

なるほど。ルートノードがbookmarkになるわけですな。

ここまでコードを書かずにコマンドライン5行の実行だけでアプリになるRailsはすばらしいですね。

つづく。
