rakeアセット：データベースへの接続を試みるプリコンパイル

rake assets:precompile --traceを実行したときに、アプリケーションがデータベースに接続しようとしている理由をデバッグしようとしています。

私はおそらくスタックトレースに何かが欠けています...誰かが関連する行を見ますか？

rake assets:precompileデフォルトでアプリを初期化します。これには、データベースへの接続が含まれます。

内部config/application.rbこれを追加できますが、警告については以下のリンクを参照してください。

config.assets.initialize_on_precompile = false

アセットのプリコンパイルに関するRailsガイド

Dylan Markow

状況に応じて、どの環境に対して選択するかを選択できますassets:precompileは、次のコマンドで機能するはずです。

rake assets:precompile:all Rails_ENV=development Rails_GROUPS=assets

通常、これは私の展開にとって意味があります。

  1. 開発マシンでアセットを生成するためにrakeを作成します（vpsのメモリが何らかの理由で制限されているため）
  2. パブリック/アセットで生成されたアセットを使用してすべてのアプリケーションを圧縮します
  3. Zipをvpsに転送し、そこでパッケージを解凍します

それが役に立てば幸い。

私も同じ問題を抱えていました。 Sprocketsをバージョン3に更新した後、アセットをローカルでプリコンパイル（開発）しようとしたが、本番環境の設定を使用すると、次のエラーが発生しました。

レーキが中止されました！ Gem :: LoadError：データベースアダプタに「postgresql」を指定しましたが、gemがロードされていません。 gem 'pg'をGemfileに追加します（そして、そのバージョンがActiveRecordに必要な最小値であることを確認します）。

ローカル（開発）ではMySQLを使用し、サーバー（本番）ではPostgresを使用しているためです。

config.assets.initialize_on_precompileはRails 4.2.1で使用できないため、解決済みとしてマークされた回答は機能しません。

解決するために、私は3つの簡単なステップに従いました。

  1. Gemfileに、次を追加します。gem "activerecord-nulldb-adapter"

  2. database.ymlで、アダプターを次のように変更します。

    production:
  adapter: <%= ENV['DB_ADAPTER'] ||= 'postgresql' %>

  3. プロダクションアセットをローカルでコンパイルします。ターミナルで実行する

    DB_ADAPTER=nulldb Rails_ENV=production rake assets:precompile

この解決策は私に解決し、私は ここ を見ました。
