# Model Preparation

In order to use Larupload in a Laravel model, the `Larupload` trait needs to be added to the model class. The `attachments` method needs to be defined in the model, which specifies all the attachments of that model.

```php
<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Mostafaznv\Larupload\Enums\LaruploadMode;
use Mostafaznv\Larupload\Storage\Attachment;
use Mostafaznv\Larupload\Traits\Larupload; 
    
class Upload extends Model
{
    use Larupload;
    
    /**
     * Define Upload Entities
     *
     * @return Attachment[]
     */
    public function attachments(): array
    {
        return [
            Attachment::make('main_file'),
            Attachment::make('other_file', LaruploadMode::LIGHT),
        ];
    }
}
```
