Reading a Poll record with validation in restful api

Step 01: Setting up route for show() method in PollController in routes/api.php

Route::get( '/polls', [PollController::class,'index']);

Step 02: Adding show() method in PollController

namespace App\Http\Controllers;

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

class PollController extends Controller
{
    //
    public function index() {
        return response()->json(Poll::get(),200);
    }    

    public function show($id) {
        return response()->json(Poll::find($id),200);
    }    
}

Step 03: Changing show() method with validation of missing record if query does not find any poll

public function show($id) {
	$poll = Poll::find($id);
	if(is_null($poll)){
		return response()->json(null,404);
	}
	return response()->json($poll,200);
}

For above, if poll is not found response will return empty json array {} like this with response code of 404 which means not found.

Now in browser if url is browsed like below this in local server this will a specific given poll that are in database

http://localhost:8000/api/polls/2
