Call to a member function connection() on a non-ob

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'

Full error

Edit :

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Setting extends Model {

}

回答1:

go to bootstrap/app.php

Just uncomment

$app->withEloquent();

Working with models in your settings files is not the best way to use them.

Your problem is, that your model query started BEFORE Laravel started it's services. That's why, when you try to make your query, model can't resolve it's connection, because DB service hasn't been initiated.

If you want do this stuff, create your own ServiceProvider and update your config there, or do it right in the boot method of your existing AppServiceProvider.

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{

}
