<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Todo;

class TodosController extends Controller
{
    //...


    public function show($id, Request $req)
    {
        $todo = Todo::find($id);
        
        // If the request has header `Accept: */json`, return JSON
        if ($req->wantsJson()) {
            return $todo;
        }
        
        // Otherwise, return view
        return view('show', ['todo' => $todo]);
    }
//...
