i want to insert the data that comes from one form, i tried this:

student model

        <?php

namespace AppModels;

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;

class Etudiant extends Model
{
    protected $table = 'students';
    protected $primaryKey = 'idStudent';
    public $timestamps = false;
    protected $fillable = [
        'dateNaissance',
        'filier',
        'niveauEtude',
        'cne',
        'specialite'
    ];

    public function user(){
        return $this->belongsTo(AppModelsUser::class);
    }
    use HasFactory;
}

user model

    <?php

namespace AppModels;

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;

class Utilisateur extends Model
{
    protected $table = 'users';
    protected $primaryKey = 'idUser';
    public $timestamps = false;
    protected $fillable = [
        'nom',
        'prenom',
        'password',
        'email',
        'numTel'
    ];

    public function student(){
        return $this->hasMany(AppModelsStudent::class);
    }

    use HasFactory;
}

Student Cotroller

    <?php

namespace AppHttpControllers;

use IlluminateHttpRequest;
use AppModelsUsers;
use AppModelsStudent;

class StudentController extends Controller
{

    protected $student;
    protected $user;
    protected $studentData;
    protected $userData;
    public function __construct(){
        $this->student = new Student();
        $this->user = new Utilisateur();
    }


    /**
     * Store a newly created resource in storage.
     */

    public function store(Request $request)
    {

        $studentData = array_diff_key($request->all(), array(['nom', 'prenom', 'password', 'email', 'numTel']));
        $userData = array_diff_key($request->all(), array(["dateNaissance", "filier", "niveauEtude", "cne", "specialite"]));

        $this->user->student()->create($userData);
        $this->student->user()->create($studentData);

        return [];
    }}
