Rails 4のアセットが本番で見つかりません（ダイジェストパスはOKです）

Question

私は本番環境の資産に問題があります。

スタイルシート、JavaScriptまたは画像を読み込むことができません。

何かにアクセスしようとすると、エラーが表示されます - 見つかりませんでした しかし、私は-digestでアクセスしようとすると大丈夫です。私は資産が正常にマニフェストカピストラーノを経由して展開し、プリコンパイルされてい

- >

おかげ

assets_manifest.json

ログ：スタイルシートのエラー（themes_for_rails宝石を搭載したスタイルシート） 私は/資産/デフォルトへのアクセスを試みます

：/stylesheets/application-ec9a310f792c60f2f77810cfcd9b903f.css、すべてOK

Answer 1

私はあなたに同様の問題を持っています。ここで

はIMAGE_TAGリンクのための私のソリューションです：（IMAGE_TAGのasset_pathを使用）の代わりに、このようなIMAGE_TAG「/pic.ext」は：

<%= image_tag asset_path("combat_elephant.png") %> 
<%= link_to (image_tag asset_path("puskay_pivka_zahvatyat.png")), "/path" %> 

また、私は、静的な資産を提供するためnginxのを使用していますので、私は設定を持っていますここで説明するようにあなたが同じ問題を抱えてされる可能性があります

Answer 2

を助け.serve_static_assets =偽とconfig.assets.compile =真

希望：No route matches [GET] /assets

基本的に、あなたのアプリをテストするためにrailsサーバーを使用している場合、プリコンパイルされたアセットはデフォルトでは提供されません。 Railsは、Webサーバー（Apache、nginxなど）がそれらを提供することを期待しています。 config/environments/production.rbに変更を加え、serve_static_assetsをtrueに設定する必要があります。
