Rails 4以降のアプリケーションでは、私はHEROKUにアプリケーションをデプロイしましたが、静的イメージは本番環境ではロードされていませんが、開発中です。

Question

私は過去2日間すべての回答を試みましたが、問題は私の静的なイメージは、プロダクションでは読み込まれませんが、開発では罰金です。私はさらにbundle exec rake assets:precompile RAILS_ENV=productionを持っています。これが動作し、私の資産をプリコンパイルします。 Public/Assetsフォルダに静止画像が表示されます。私が見つけた

    config.eager_load = true 

    # Full error reports are disabled and caching is turned on. 
    config.consider_all_requests_local  = true 
    config.action_controller.perform_caching = true 

    # Enable Rack::Cache to put a simple HTTP cache in front of your application 
    # Add `rack-cache` to your Gemfile before enabling this. 
    # For large-scale production use, consider using a caching reverse proxy like 
    # NGINX, varnish or squid. 
    # config.action_dispatch.rack_cache = true 

    # Disable serving static files from the `/public` folder by default since 
    # Apache or NGINX already handles this. 
    config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?

end 

もう一つ興味深いのは、私の静的なイメージがpublic/assetsしているにもかかわらずだった、イメージタグは、公開を指していない、images/abc.jpgのようSRCリンクを持っていますアセットイメージ

コード

<%= link_to root_path,class:"navbar-brand" do %> 
    <h1><%= image_tag("logo",alt:"Bitnotes") %></h1> 
<% end %> 

Answer 1

は4日間を試した後、ここで宝石が資産をプリコンパイルすることはできません

gem 'tinymce-rails', '~> 4.3', '>= 4.3.8' 

問題

の上にソリューションです。だから私は、上記の宝石を取り出して、production.rbでこの config.assets.compile = true変更を行った後 application.js

から

//= require tinymce 
//= require tinymce-jquery 

を削除しました。

bundle exec rake assets:precompile RAILS_ENV=production 

と

最後にプリコンパイルされた資産は、すべての変更をコミットし、イメージタグのためにあなたのコードを追加することができ

git push heroku master

Answer 2

このgem 'rails_12factor', group: :productionをGemfileに追加し、Herokuに再度デプロイすることができます。 production.rbファイルにconfig.serve_static_filesを設定する必要はありません。
