Simple trait to automatically add slugs to eloquent models

Just add this trait to your model and you should be good to go. Modify if you need more complex logic.

<?php

namespace App\Traits;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;

trait HasSlug
{
    protected static function bootHasSlug(): void
    {
        static::creating(function (Model $model) {
            $attr = $model->sluggable_attribute ?? 'title';
            $model->slug = Str::slug($model->{$attr});
        });

        static::updating(function (Model $model) {
            $attr = $model->sluggable_attribute ?? 'title';
            $model->slug = Str::slug($model->{$attr});
        });
    }
}
