PHP Colleagues:

This question relates to best practices for using Laravel Cache.

The central objective is to reduce the number of accesses to the database for all the usual
performance-related reasons.

Are there any documented best practices for the application design?  It seems obvious to me
that since Cache:: is a one-line statement, it's easy to drop this into the controllers --
either return the cached data or call the model and cache the results. And invalidate the
cache (maybe with an eager reload) when requests update the model.

Here's a first look at doing this in the controller

    /**
     * Retrieve listing of the gallery resource.
     *
     * @uses GET /gallery to return all image_collections.
     *
     * @param int $id The gallery id
     *
     * @return Response - Contains a HTTP code and a list of articles.
     */
    public function index()
    {
        $response_data = array();
        $response_code = 200;
       
        // TRY TO RETURN A CACHED RESPONSE
        $cache_key = "gallery_index";
        $response_data = Cache::get($cache_key, null);
       
        // IF NO CACHED RESPONSE, QUERY THE DATABASE
        if (!$response_data) {
            try {
                $response_data['items'] = $this->gallery->all();
                Cache::put($cache_key, $response_data, Config::get('app.gallery_cache_minutes'));
            } catch (PDOException $ex) {
                $response_code = 500;
                $response_data['error'] = ErrorReporter::raiseError($ex->getCode());
            }
        }
       
        return Response::json($response_data, $response_code);
    }

I've heard the suggestion that you could use Laravel Route Filters to cache the responses,
but I can't quite get my head around the idea.

Thoughts?  References?  Examples?

Thanks to all,
Ray
