Fatal error: Uncaught InvalidArgumentException: Unsupported driver

I am a Chinese user, can not speak English, or a PHP rookie, this is using Google automatic translation, I apologize first. I encountered an error using the model, What did I do wrong?

Fatal error: Uncaught InvalidArgumentException: Unsupported driver

My program code:

App\Controllers\UserController.php

namespace App\Controllers;

use Leaf\Controller;
use App\Models\User;

class UsersController extends Controller
{
    public function index()
    {
        $users = User::all();
        foreach ($users as $user) {
            echo $user->name;
        }
    }

App\Models\User.php

namespace App\Models;

use Leaf\Model;

class User extends Model
{
    protected $table = 'users';
    public $timestamps = false;
}

My database connection：

$db = new Leaf\Db("localhost", "root", "root", "demo");

Hi @wfsdaj, thanks for trying out Leaf. First of all, can you give me some information on your setup? Are you using Leaf on it's own or something like Leaf MVC/Leaf API?

[mychidarko]

Also, Leaf Models run on eloquent, and not Leaf DB, that may be one of the reasons you're encountering this problem, but I can't say so just yet, which is why I need a more information on your setup

[wfsdaj]

@mr-phlames thank you for your reply. I use Leaf. I can use the db class normally on the index page.

leaf/index.php

require __DIR__ . "/vendor/autoload.php";
$app = new Leaf\App();
require __DIR__ . "/config/app.php";
require __DIR__ . "/app/routes.php";

$users = $db->select("users", "id, name")->fetchObj();
echo $users->id;        //output 1

$app->run();

[mychidarko]

Yes the DB class just provides a simple way to use your database. Something you can work with anywhere in your code without worrying about models and stuff like that. So in that case, is you problem resolved or do you still have issues with the database?

[wfsdaj]

Yes, there are still errors. 😅

[mychidarko]

Can you confirm something for me? Do you have a .env file in your setup?

[wfsdaj]

my /.env file

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=demo
DB_USERNAME=root
DB_PASSWORD=root

my /config/app.php

$app->config([
    'mode' => 'development',
    'debug' => true,
    'templates.path' => './views',
    'log.enabled' => true,
    'cookies.path' => '/',
    'cookies.encrypt' => true,
    'cookies.lifetime' => '20 minutes',
]);

[mychidarko]

And are you correctly loading the .env variables into your code?

[wfsdaj]

I thought the .env file was automatically loaded just like laravel。
How can I load .env file correctly? require vlucas/phpdotenv？

[mychidarko]

Yeah, that should be the easiest way.

Env files are loaded automatically only if you use something like leaf MVC or leaf API.
