[devise]新規登録ができない。

Question

#状況
deviseのgemをbundle installをして、新規登録をしようとするとターミナルで「Unpermitted parameters: :family_name, :first_name, :gender, :age」とエラーが出ています。

family_nameもfirst_nameもgenderもageも全てストロングパラメータで許可をしているのですが、なぜ許可されていないパラメータとなってしまうのかが分かりません。。。

どなたかご教示いただけると幸いです。

参考として、userに関するmodelとcontrollerとmigrateファイルの記述を下記に載せています。

Answer 1

公式リポジトリの説明は読みましたか？
あまり難しい使い方をしてない限りは、説明通りで動くのではないでしょうか。
https://github.com/heartcombo/devise#strong-parameters

多分、こんな感じ。

class ApplicationController < ActionController::Base
  before_action :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:sign_up, keys: [:family_name, :first_name, :gender, :age])
  end
end
