Devise導入後、サインアップ・サインイン画面に遷移したい

Question

前提

Railsでケーキ屋の通販サイトを作っています。
要件に沿って顧客と管理者で機能を分けて作成しています。

実現したいこと

Deviseを使ったログインをしたいが、トップページから顧客のサインイン、サインアップ画面に遷移できないので、できるようにしたいです。

試したこと

• application_controllersとdevise.rbにcustomerのサインアップに必要なカラムを追加

補足情報（FW/ツールのバージョンなど）

ruby:3.1.2

Answer 1

一度アプリケーションを消してもう一度作り直し、落ち着いてマイグレーションファイルのカラムの設定や、Viewページを作成したら表示されました。
おそらく編集しているうちに余計なものまで消してしまっていたのかもしれません。
