如何从数据库中获取随机行并将同一行显示给 laravel 中的所有用户？

Question

Is there any way to fetch a random row from the table and display the same row to all the users? I know i can use the random() method to get the row but how do I display the same row to all the users.

Here's my Controller:-

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Database\Query\Builder::inRandomOrder;
use App\Nothingness;

class NothingnessController extends Controller
{
    public function randomQuestion()
    {
        $seed = Carbon::now()->toISOString();
            Nothingness::inRandomOrder($seed)->first();
            return view('home', compact('seed'));
    }
}

This is a new laravel project

Use Illuminate\Database\Query\Builder::inRandomOrder method and provide it a seed.

This method is implemented in Eloquent models via __call magic method.

The seed ensures that the results are ordered the same for the same seed.

The following is a query where everyone viewing at the same minute of day sees the same record.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Carbon;
use App\Nothingness;

class NothingnessController extends Controller
{
    public function randomQuestion()
    {
        $seed = Carbon::now()->format('Y-m-d H:i');
        $randomNothing = Nothingness::inRandomOrder($seed)->first();
        return view('home', compact('randomNothing'));
    }
}

You could also have seed come from an external source.
