laravel - 在 Laravel 5 上的非对象错误上调用成员函数 connection()

Question

我想在数据库上存储用户配置数据，我正在关注这个论坛主题 http://forumsarchive.laravel.io/viewtopic.php?id=10406
但是当我实现它时，laravel 会抛出一个错误。
我运行了 composer dump-autoload 但似乎没有任何工作。这里有什么问题？

//文件名: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;

用法:

echo Config::get('settings.token');//返回“内容”的值

完全错误

编辑:

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Setting extends Model {

}

运行时 测试用例 在 Laravel 6.x 及以上 ，我经常遇到这个错误。我意识到单元测试是从 PHPUnit TestClass 而不是 Laravel TestCase 扩展的。所以改PHPUnit\Framework\TestCase;至 Tests\TestCase .

<?php


use Tests\TestCase;

class ArtifactTest extends TestCase{

}
