Q&A
ruby on rails チュートリアルを使って練習中です。
第２章のアプリ、を実装、ローカルで問題なく作動したので、Herokuへデプロイ。しかし、Open appボタンからページを開いたところ、Application error が発生し、logを読んでもその対策がわからないので、同じ状況を経験した方などお教えいただけますと幸いです。
おそらく、/app/vendor/bundle/ruby/2.3.0/gems/activesupport-5.1.4/lib/active_support/concern.rb:126:in `included': Cannot define multiple 'included' blocks for a Concern (ActiveSupport::Concern::MultipleIncludedBlocks)の箇所が悪さをしていると思うのですが、ネットで検索しても解決方法にたどり着けない状況です。
Concernメソッドを定義する必要があるという事なんですかね。
