- どの処理までうまく動いているのか
mvpレビューの依頼後、プロフィール画面に飛べていましたが、カスタマイズ画面へのリンクがうまくいかなかったため、修正をした後からこのエラーが出現しました。

- エラーから考えられる原因
ユーザー情報がうまく渡っていないためnilになっていると考えられる。
- 試したこと
ログイン状態でプロフィールに飛ぼうとした->上記のエラー
ユーザー登録後のリダイレクトでプロフィールに飛ぼうとした->上記のエラー
何が原因でこうなったのかわからない状態です。

current_userは取得できていますでしょうか？ また、

def profile
    if current_user
      @user = current_user
    else
      redirect_to new_user_session_path
    end
  end

で@userにcurrent_userを代入しているので、こちらも確認してみてください。

current_userの取得についてはエラー文だとうまくいってないみたいですが、 ChatGPTにUsers::RegistrationsControllerとUsersControllerで取得できているか確認をしたら取得できていると返ってきました。 デバックを行ったところ

となっていたので、 customize が存在しないため、customize.present? のチェックが失敗してエラーになっていることが判明しました。

[kodamarisa]

profile.html.erbを

<% if user_signed_in? %>
  <h1>Your Profile</h1>
  <p><strong>Name:</strong> <%= @user.name %></p>
  <p><strong>Email:</strong> <%= @user.email %></p>
  <% if @user.customize.present? %>
    <%= link_to "Edit Customize", edit_customize_path(@user.customize) %>
  <% else %>
    <%= link_to "Create Customize", new_customize_path %>
  <% end %>
  <%= link_to 'Logout', destroy_user_session_path, method: :delete %>
<% end %>

この形にし、 ルーティングを

 # Customize routes
  resources :customizes, only: [:new, :edit, :create, :update]

こうしたら、上記のエラーがなくなり、プロフィール画面に飛ぶことができました！
