### 前提・実現したいこと railsでwebアプリケーションの課題に取り組んでいます。完成間近なのですが、最後にバリデーションをかけたところ新規登録ができなくなりました。 validates :introduction, presence: true, length: {maximum: 50} このバリデーションをプロフィールの自己紹介文にだけかけたいのですが、どうも新規登録にもかかってしまうのが原因だと考えております。解決策のご教授をお願いいたします。 ### 発生している問題・エラーメッセージ ![イメージ説明](b5d85a2196f07fd19e3738eecc7b884a.png) ### /bookers2/app/models/user.rb ``` class User < ApplicationRecord # Include default devise modules.

``` ### 試したことバリテーションを外せば新規登録できましたが、もちろん自己紹介文にはバリテーションはかかりませんでした。 ### 新規登録を押した時のターミナルです。 ``` Started POST "/users" for 119.229.201.247 at 2021-04-08 14:39:26 +0000 Cannot render console from 119.229.201.247!
