Rails 5を使用しています
新しいフィールドusernameをモデルUserに追加しました。
class Users::RegistrationsController < Devise::RegistrationsController
before_action :configure_permitted_parameters
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up).push(:username)
end
end
登録中にエラーが表示されます:#の未定義メソッド「for」フォーク
痕跡:
NoMethodError(#の未定義メソッド「for」ですか?フォーク?):
