私は Rails と stackoverflow にかなり慣れていないので、明示的にしようと思います。私は誰かのプロジェクトを変更するように頼んでいたので、ソースを入手し、自分の仕事用コンピューター (Windows 上にある ...) で動作させて、ローカル ブラウザー (cf : rails s) でテストします。プロジェクトはすでに本番環境にあるため、機能していると思われるため、問題は自分の作業環境にあると思います。必要なすべての gem をインストールした後、bundle install を実行してデータベース サーバーを起動し (プロジェクトは mongodb を使用しています)、rails サーバーを実行します。コマンドは実際には機能しますが、localhost アドレス (http://localhost:3000/) の任意のブラウザーを使用してアプリケーションに接続しようとするとすぐにエラーが発生し、原因がわかりません...

これは私が得るログです:

そして、これは言及されているコントローラーです:

class HomeController < ApplicationController
  def index
    @presenter = Home::IndexPresenter.new
    @article_presenter = Articles::IndexPresenter.new(Article.with_state(:published).last)
  end
end

誰かが私を助けることができれば、それはとても親切です. 何かを言い忘れていないか尋ねてください。ありがとうございます。

根本的な問題は、リクエストされた URL がHTTP 406 コードを返していることです。これは、rest_client実行することで確認できます。curl

curl --include https://api.localeapp.com/v1/projects/hhMxHgKAzj9p1dFuS0GnTTnemJ5F9dXLDuCa1KacQSymUcmTFk/translations.yml?updated_at=1354612995

(Windows 環境にいることに気付きました。アクセスできないcurl場合は、インストールできるいくつかのツールを使用して要求を行うことができます)

次に、コントローラー内で、RestClient 呼び出しからの応答が成功したかどうか (2xx ステータス) を確認するチェックがないようです。RestClient が例外を発生させるため、アプリケーションで 500 エラーが発生します。

そのため、URL が機能しない理由がわからない場合は、提供されている API を確認する必要があります。localeapp.com

ただし、API が外部サービスであることを考えると、ソフトウェア内にエラー処理を追加することもできます。RestClient として知られているものはいくつかありますが、それがアーキロックによるものである場合、ドキュメントには「結果処理」の良い例が示されています。
