Illuminate\Database\QueryException SQLSTATE[HY000] [2002] 没有这样的文件或目录，但迁移有效
Illuminate\Database\QueryException SQLSTATE[HY000] [2002] No such file or directory but migrations works
第一次通过网络询问，但我不知道我能做什么。
我的问题是关于 laravel 使用 Eloquent。我对迁移和播种没有任何问题，并且与 MySQL 有联系。但是当我尝试构建一个控制器并想将数据存储在我现有的 table 汽车上时。这是一个例子：
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Car;
class DatenController extends Controller
{
public function work()
{
$car = new Car;
$car->save();
return 'Erfolg!';
}
}*
但是当我想启动使用该方法的 URL 时，会出现以下错误：
Illuminate\Database\QueryException
SQLSTATE[HY000] [2002] 没有这样的文件或目录 (SQL: 插入 cars (updated_at, created_at) 值 (2022-01- 16 13:26:17, 2022-01-16 13:26:17))
我查看了其他解决方案，但他们只讨论了与 MySQL 的连接，并且由于迁移，我认为我的连接完全没问题。
我用我的环境尝试了一切。和 database.php 文件，但没有发现任何错误。也许你可以帮助我。

感谢您的帮助。有什么不明白的地方我会尽快回复的。
你好 Fermain
您必须为时间格式提供 created_at 和 updated_at 值，否则您应该在数据创建到特定 table 时自动更新。
您在特定型号中提供以下行
public $timestamps = true;
我找到了问题的答案。我同时使用了 MAMP 和 Docker。问题是Mama在服务器上，docker在电脑上是lokal。所以我有两个数据库。但是 Docker 中没有设置数据库的密码。所以我可以使用 env 中的属性访问我的服务器数据库。而且无法访问 eloquent 想要存储的我的 docker 数据库。所以我从我的电脑上删除了 MAMP 并尝试使用
docker exec -it MySQL MySQL -uroot -p
访问 MySQL 但密码错误。所以我使用了 nischay 的 命令，这会生成一个新密码。这个密码我设置在docker exec -it MySQL MySQL -uroot -p，我在MySQL bash。在此之后，我使用 ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password;
重置密码
