前回の続きで詳細画面を作っていこうと思います。(next.js+rails+mysql)

backend/app/controllers/todos_controller.rb

class TodosController < ApplicationController
    
    def index
        # 日付が新しい順に10件まで取得する
        @todos = Todo.all.order(created_at: :desc).limit(10)
    
        render json: @todos
    
    end
    
    def show
    
        @todo = Todo.find(params[:id])

    render json: @todo
    end
   end

/frontend/app/todos/[id]/page.tsx

"use client";

import { useEffect, useState } from 'react';
import { useRouter } from 'next/navigation';
import useSWR from 'swr';
import Link from 'next/link';
import Todo from '@/components/Todo';
import { TodoType } from '@/types/Todo';
import axios from 'axios';

// Fetcher function for SWR
const fetcher = (url: string) => axios.get(url).then(res => res.data);

// Todo詳細ページを表示するコンポーネント
const TodoDetail = ({ params }: { params: { id: string } }) => {
  // ルーティング情報を取得する
  const router = useRouter();
  const { id } = params;

  // SWRを使ってデータを取得する
  const { data: todo, error } = useSWR<TodoType>(id ? `http://localhost:3000/todos/${id}` : null, fetcher);

  // エラーが発生した場合の処理
  if (error) return <div>Failed to load</div>;

  // Todoを取得中の場合は「Loading...」を表示する
  if (!todo) return <div>Loading...</div>;

  return (
    <div className="flex justify-center items-center">
      <div className="flex flex-col space-y-6 w-3/4 max-w-lg pt-10">
        <label className="block text-xl font-bold text-gray-700">Todo</label>
        <Todo todo={todo} />
        <div className="flex justify-end">
          <Link
            href="/"
            className="mt-auto font-medium text-blue-600 hover:bg-blue-300 focus:outline-none"
          >
            Back
          </Link>
        </div>
      </div>
    </div>
  );
};

export default TodoDetail;

これでdocker-composeを行い、localhost:3001するとデータが表示されるのでそれをクリックして詳細画面が出るはずです。
