Call to a member function connection() on a non-object error on Laravel 5

Question

I want to store user configuration data on database and I'm following this forum thread about it http://forumsarchive.laravel.io/viewtopic.php?id=10406 but when I implemented it laravel throws an error. I ran composer dump-autoload but nothing seems to be workign.What's the problem here?

// filename: app/config/settings.php

use \App\Models\Setting

$list = array();

$format = function(&$list, $keys, $val) use(&$format) {
    $keys ? $format($list[array_shift($keys)], $keys, $val) : $list = $val;
};

foreach(Setting::all() as $setting) {
    $format($list, explode('.', $setting->token), $setting->content);
}

return $list;

Usage:

echo Config::get('settings.token'); // returns value of 'content'

Edit :

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Setting extends Model {

}

Answer 1

go to bootstrap/app.php

Just uncomment

$app->withEloquent();

Answer 2

While running TestCase in Laravel 6.x and above, I often encounter this error. I realized that the unit test is extended from PHPUnit TestClass rather than Laravel TestCase. So change PHPUnit\Framework\TestCase; to Tests\TestCase.

<?php


use Tests\TestCase;

class ArtifactTest extends TestCase{

}
