Q&A
前提・実現したいこと
missing required keys: [:id]エラーを解消してcard_listのshowページを開く
発生している問題・エラーメッセージ
エラーメッセージ ActionController::UrlGenerationError (No route matches {:action=>"show", :admin_id=>#<CardList id: 1, admin_id: 1, name: "久兵衛", address: "東京", opening_hours: "2000-01-01 12:00:00", closing_hours: "2000-01-01 22:00:00", phone_num: "9999999999", url: "http://www.kyubey.jp/", created_at: "2020-03-20 08:22:26", updated_at: "2020-03-20 08:22:26">, :controller=>"card_lists"}, missing required keys: [:id]):
該当のソースコード
card_lists_controller.rb class CardListsController < ApplicationController def new @card_list = CardList.new end def create @card_list = CardList.new(card_list_params) if @card_list.save redirect_to admin_card_list_url(@card_list), notice: "カード登録が完了しました" else render "new" end end def show @card_list = CardList.find(params[:id]) @point_lists = PointList.where(card_list_id: params[:card_list_id]) @coupon_lists = CouponList.where(card_list_id: params[:card_list_id]) end private def card_list_params params.require(:card_list).permit( :name, :address, :opening_hours, :closing_hours, :phone_num, :url, :image).merge(admin_id: session[:admin_id]) end end
createアクションのredirect_to admin_card_list_url(@card_list)の部分でエラーが起きています。
疑問
パラメータを見るとcard_listのidが入っているように見えるのですが、なぜidがないと言われるかがわかりません。
パラメータが:admin_id=>#となっているのが問題でしょうか？
ご教授のほどよろしくお願いいたします。
補足情報（FW/ツールのバージョンなど）
admins_controller.rb class AdminsController < ApplicationController include Admins::SessionsHelper def new @admin = Admin.new end def create @admin = Admin.new(admin_params) if @admin.save log_in @admin redirect_to new_admin_card_list_url(@admin), notice:"アカウント登録が完了しました" else render "new" end end private def admin_params params.require(:admin).permit(:name, :email, :admin, :password, :password_confirmation) end end
上記のcreateが完了したらcard_listのnewページに飛びます

admin_card_list GET /admins/:admin_id/card_lists/:id(.:format)
こうなっているように、admin_card_listを使うには、admin_idとidの2つを与える必要があります。
