Rails
Ruby on Rails
原則
DRY (Don't Repeat Tourself)
同じことを繰り返さないこと
Convention over Configuration
設定よりも決まりごとを優先すること
Railsのインストール
さくらレンタルサーバ(スタンダード以上のプラン)のユーザ領域に入れる。
rubyは最初から入っているのでインストールする必要はない。
さくらのレンタルサーバにRailインストール
環境変数の追加
%vi .cshrc setenv RUBYLIB $HOME/local/lib setenv GEM_HOME $HOME/local/lib/ruby/gem (RUBYLIBに余計なパスを突っ込むと、NameErrorで失敗ので注意)
