Cache Eloquent Queries - Boot OR Service Provider OR ...

There must be a better way of caching teh model. Let’s assume 5 product families with 5 products in each product family with approx 20 product features for each product i.e. a family will have 5 products and each will have 20 features so a total of 100 features for each family. So the relation will be product_family -> hasMany products -> hasMany features.

Example, family = SEO and products Audit, Local SEO, eCommerce SEO. Mobile SEO, and Voice SEO. I want to cache the family with products and features or each product with features.

The example below works, but doesn't seem elegant.

Other options might include:

1. A service provider (ProductsServiceProvider) that caches all requests on boot
2. A Model boot trait
3. A get attribute mutator

Thoughts?

<?php


namespace App\Products;


use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\Cache;

class Product extends Model
{
    /**
     * Create unique cache key
     *
     * @param string $slug
     * @param array $relations
     * @return string
     */
    public function cacheKey($slug = "", $relations = [])
    {
        return sprintf(
            "%s-%s-%s",
            $this->getTable(),
            $slug,
            implode("-",$relations)
        );
    }


    /**
     * Cache Product of slug
     * 
     * @param $slug
     * @param array $relations
     * @return mixed
     */
    public function getCachedProductOfSlug($slug, $relations = [])
    {
        return Cache::remember($this->cacheKey($slug, $relations) , 60, function ()  use($slug, $relations) {
            return $this->where('slug',$slug)->with($relations)->first();
        });
    }

    /**
     * Product of slug
     *
     * @param $slug
     * @param array $relations
     * @return mixed
     */
    public function productOfSlug($slug, $relations = [])
    {
        return $this->getCachedProductOfSlug($slug, $relations);
    }
}
