投稿に対してのコメントが表示されない

Question

前提

プログラミング初学者です。
本の感想を投稿できるサイトを作っています。投稿に対してのコメントを実装中なのですが、コメントを投稿しても同じページにリダイレクトされるだけでコメントは表示されず、エラーも表示されないので原因が分からないでいます。ログを見ても問題なく投稿されている感じです。

実現したいこと

コメントを表示させたい

comment.save! にするなどして例外を確認してみてはいかがでしょう

[winterboum]

model User、BookComment、Book の code載せてください

[koikoikoikoi]

載せました🙏

Answer 1

book_comment.rb で belongs_to :book_comment になってるため、「関連のBookCommentが無いよ」もしくは 「column book_comment_id がないよ」のエラーで登録できて居ませんね。
belongs_to :book でしょう。
