actually this code is working but I want to know if there is a better way to do it, because I’m learning laravel 11.
If this is not the place to make this question can somebody tell me where can I ask the question?

    public function generateQR(Request $request) {
        $qr = $request->get('qr');
        $pass = $request->get('pass');
        do {
            $code = $this->generateRandomString();
            $qrcode = Qrcode::find($code);
        } while($qrcode != null);
        $qrcode = new Qrcode();
        $qrcode->input = $qr;
        $qrcode->code = $code;
        $qrcode->pass = $pass;
        $qrcode->save();
        return $qr;
    }

Thank’s for answers!

I expect to reduce code for learning.
