Rails3, Mongoid, OmniAuth でFacebookログイン実装

最初はやはり認証。これができないと何もアプリ作れない。

$ rails new youme -m https://github.com/RailsApps/rails3-application-templates/raw/master/rails3-mongoid-omniauth-template.rb -T -O

Github から実装テンプレートを取ってくる。HTTPSの証明書エラーが出たので、ここ http://railsapps.github.com/openssl-certificate-verify-failed.html を参考にして解決。
