[asm]

提示されているエラーログは、デプロイ後にルートにアクセスし404が出た時のログのようですが
その認識で正しいでしょうか？

また、
・BlogsControllerのindexメソッド
・config/routes.rb
についてご提示お願いします。

Answer 1

@blogconfig = Blogconfig.find 1

HerokuのBlogconfigにデータが1つも入ってないもしくはid: 1が存在していないようです。
seed.rbに初期データ投入を記述するか、heroku run rails cから投入するなどの方法を取るとよいでしょう。

また、find 1よりもfirstの方がよいかもしれません。

回答ありがとうございます。find 1からfirstにしたらheroku run rails db:migrateをしても、しなくても、We're sorry, but something went wrong.というエラーひとつになりました。あと、seeds.rbにはBlogconfig.create(id:1, title:'my blog', subtitle:'サンプルで作ったブログです。', stylename:'gray')というのを書いているのですが認識されていないということなのでしょうか。

[asm]

db:seedは自動実行はされなかったはずなので
heroku run rails db:seed
が必要です。

ありがとうございます。できました！！
