Preparing your model - Laravel Medialibrary

To associate media with a model, the model must implement the following interface and trait:

php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Spatie\MediaLibrary\HasMedia;
use Spatie\MediaLibrary\InteractsWithMedia;

class YourModel extends Model implements HasMedia
{
    use InteractsWithMedia;
}

The Collection component will show a preview thumbnail for items in the collection it is showing.

To generate that thumbnail, you must add a conversion like this one to your model.

php

use Spatie\Image\Enums\Fit;
use Spatie\MediaLibrary\MediaCollections\Models\Media;

public function registerMediaConversions(?Media $media = null): void
{
    $this
        ->addMediaConversion('preview')
        ->fit(Fit::Contain, 300, 300)
        ->nonQueued();
}
