Dashboard::useModel not working with Trait's boot(), however it works fine in the orchid:admin artisan command

[mabdelfattah]

Simply, I have a trait that is generating a default value for a (NOT NULL) column called referral_code. However, when I use Orchid to create a new user, I keep getting the database error that orchid is trying to create the insert query with null value for that column "referral_code".

On the other side, when I use "php artisan orchid:admin", it works perfectly and the Trait's boot() works as expected.

Here is my service provider

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Orchid\Platform\Dashboard;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        //
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        Dashboard::useModel(
            "\Orchid\Platform\Models\User::class",
            "\App\User::class"
        );
    }
}

My User model

<?php

namespace App\Models;

use App\Traits\UserReferral;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Orchid\Filters\Types\Like;
use Orchid\Filters\Types\Where;
use Orchid\Filters\Types\WhereDateStartEnd;
use Orchid\Platform\Models\User as Authenticatable;

class User extends Authenticatable implements MustVerifyEmail
{
    use UserReferral;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = ["name", "email", "permissions", "referral_code", "referred_by"];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = ["password", "remember_token", "permissions"];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        "permissions" => "array",
        "email_verified_at" => "datetime",
    ];

    /**
     * The attributes for which you can use filters in url.
     *
     * @var array
     */
    protected $allowedFilters = [
        "id" => Where::class,
        "name" => Like::class,
        "email" => Like::class,
        "updated_at" => WhereDateStartEnd::class,
        "created_at" => WhereDateStartEnd::class,
    ];

    /**
     * The attributes for which can use sort in url.
     *
     * @var array
     */
    protected $allowedSorts = [
        "id",
        "name",
        "email",
        "updated_at",
        "created_at",
    ];
}

Trait (simplified)

<?php

namespace App\Traits;

use Illuminate\Database\Eloquent\Model;

trait UserReferral
{
    public static function bootUserReferral(): void
    {
        static::creating(function (Model $model) {
            $model->referral_code = 'tmp-ref';
        });
    }
}
