Call to a member function connection() on a non-object error on Laravel 5
提问by user3407278
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=10406but when I implemented it laravel throws an error. I ran composer dump-autoload but nothing seems to be workign.What's the problem here?
我想将用户配置数据存储在数据库上，我正在关注这个关于它的论坛帖子http://forumsarchive.laravel.io/viewtopic.php?id=10406但是当我实现它时，laravel 抛出一个错误。我运行 composer dump-autoload 但似乎没有任何工作。这里有什么问题？
// filename: app/config/settings.php
// 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;
Usage:
用法：
echo Config::get('settings.token'); // returns value of 'content'
echo Config::get('settings.token'); // 返回“内容”的值
Full error
完全错误

go to bootstrap/app.php
转到引导程序/app.php
Just uncomment
只需取消注释
$app->withEloquent();

Working with models in your settings files is not the best way to use them.
在设置文件中使用模型并不是使用它们的最佳方式。
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.
您的问题是，您的模型查询在 Laravel 启动它的服务之前就启动了。这就是为什么当您尝试进行查询时，模型无法解析它的连接，因为数据库服务尚未启动。
If you want do this stuff, create your own ServiceProvider and update your config there, or do it right in the bootmethod of your existing AppServiceProvider.
如果你想做这些事情，创建你自己的 ServiceProvider 并在那里更新你的配置，或者在boot你现有的AppServiceProvider.

While running TestCasein 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.
在Laravel 6.x 及更高版本中运行TestCase时，我经常遇到此错误。我意识到单元测试是从 PHPUnit TestClass 而不是 Laravel TestCase 扩展而来的。所以改为.PHPUnit\Framework\TestCase;Tests\TestCase
<?php
use Tests\TestCase;
class ArtifactTest extends TestCase{
}
