Padrino + OmniAuthをテンプレートで

とりあえずできた。

$ padrino g project hoge -p https://gist.github.com/3159766

みたいにするとFacebook認証する空アプリができる。

FB_APP_IDとFB_APP_SECRETを環境変数に登録しないといけない。powでやるなら簡単だね。

でも、自分の環境だとOpenSSLのverify errorとかなんとかがでる。

$ ruby -ropenssl -e 'p OpenSSL::X509::DEFAULT_CERT_FILE'
"/Users/jhoshina/.rvm/usr/ssl/cert.pem"

あー、rvm pkgで入れたやつか。空になってる。どっかからcert.pemをパクってきて上書いたら通った。

これで、認証をfacebookとかにぶん投げることができて、アプリ作りに専念できる…かな？
