Railsのbetter_errorsがVM経由だと動かない場合

More than 3 years have passed since last update.

そもそもgitに書いてあった
https://github.com/charliesome/better_errors#security

が、制限を外すIPを探そうとifconfigや、ipconfigとかしてたが
結局以下で簡単にできた。

railsのビューのどこかに

<%= request.remote_ip %>

と書いて、作ったアプリにアクセス。出てきたIPをapp/config/environments/development.rbに追加

BetterErrors::Middleware.allow_ip! "上で出たIP"
