▲固定IP付きと考えると激安ですし。

3ヶ月間無料らしいので、その間に家のネットワーク設定を変更したいと思います。
早速、DDNS設定を殺していこうっと。

しかし、livedoorをプロバイダ業者として利用させてもらう日が来るとは、夢にも思っていませんでした。
「livedoorプロバイダ」という単語を聞くのが、めちゃくちゃ懐かしいなぁ。
それだけ歳を取ったという事でしょうか。

おそらく、rails1.2系と、rails2.0系のscaffoldに違いによるエラー

教えて！ Watch Ruby on Rails について

——————————————————-
1.railsコマンドでひな形を作成
※rails2.0ではデフォルトのDBがSQLite3なので、mysqlで使う場合は”-d mysql”オプションが必要かもです。
2.database.ymlを修正
3.おもむろにscaffold実行
ruby script/generate scaffold pepole name:string age:integer
4.dbにデータベースを作る
5.mygrateする
rake db:migrate
6.serverをスタートする
——————————————————-
↓
NetBeansのチュートリアル手順を改造するとこんな感じか
——————————————————-
１．db内にデータベース作成する。
２．初期ウィザードで、Mysql指定（これでdatabase.ymlも自動生成）
３．scaffold生成
４．mygrationファイル修正
５．mygrate
６．実行！
——————————————————-

明日やってみる。

■どうやら、すでに同名のデータベースがある模様。（アンインストールに失敗していた？）
mysql> show databases;

| information_schema |
| depot_development |
| mysql |
| rubyweblog_development |

+————————+
5 rows in set (0.23 sec)

■不要なデータベースを削除
mysql> drop database depot_development;
Query OK, 2 rows affected (0.33 sec)

mysql> drop database rubyweblog_development;
Query OK, 0 rows affected (0.00 sec)

mysql> drop database test;
Query OK, 0 rows affected (0.02 sec)

mysql> quit;
Bye

■無事作成できた。
