私の問題は、Heroku DataMapper にデプロイすると、データベース接続情報のこの部分を完全なデータベース接続として使用しようとすること'postgres://postgres:myohmysosecret@localhost/recall'ですDataMapper.setup(:default, ENV['DATABASE_URL'] || 'postgres://postgres:myohmysosecret@localhost/recall')。

これが私のHerokuログファイルです：

私はこの問題を抱えていました。最終的には、Heroku チュートリアルにある以下に関連しているように見えましたが、一見エラーのようです:

ENV['DATABASE_URL']

基本的に、おそらくデータベースはありません。ランニングheroku configはこれを示しています。ここで詳しく説明されているように、データベースを作成する次の行を実行できます。

heroku addons:add heroku-postgresql:dev

次に、heroku configもう一度実行してデータベース文字列を取得するか、おそらく DataMapper.setup で次の行を使用できます。

ENV['HEROKU_POSTGRESQL_CYAN_URL']

お役に立てれば！これを自分の Heroku サポート チケットに追加して、彼らの意見を確認しました!
