私が思うに、問題が登録コントローラーにあることは理解していますが、そのようなコントローラーはありません。インターネットで解決策を探しましたが、何も見つかりませんでした。多くの時間を費やしただけなので、あなたの助けが必要です.

問題が解決しました：

Devise のユーザー モデルを作成していたとき、移行に email 属性を含めました。ユーザーモデルにデバイスを追加するときに問題がありました。デフォルトでメールフィールドも追加されるため、以前の移行と競合していました。

これらのバグを処理する時間がないので、解決できてよかったです。助けてくれてありがとう。

ユーザーモデルの属性の種類が間違っているようです。データベースに有効なタイプのフィールドが含まれていることを確認してください。詳細はこちら：https ：//github.com/plataformatec/devise

問題は、大文字と小文字を区別しない既知のキーの問題に関連している可能性があります。次のスニペットをconfig/initializers / devise.rbファイルに追加します：http：//anti-pattern.com/case-insensitive-keys-with-devise

登録コントローラーはDeviseライブラリで定義されており、Gemfileにdeviseを追加すると、アプリケーションコントローラーに自動的に追加されます。

一部のフィールドの数値情報を提出していますか? ユーザー名の「123」のような？文字列として数値を取得しているが、実際には数値であると考えている場合、これは Devise の問題である可能性があります。
