![]() Which obviously didn't work, because $scores is an object and it was expecting an array. So preferably like the above method with eloquent, where I output $score->ratingtext, $score->ratingradio, $score-id, and whatever I want. But I don't only want to display the comment, I also want to be able to display all Information regarding this Element. $comments = array_reverse($comments, true) Īnd then looping through the $comments. Reverse the array, to have the latest element first displayed $comments = array_slice($comments, -20, 20, true) ![]() $commenttype = $scores->lists('ratingradio') The more data there is the more time it will. When you make a query, the data that the database returns is sent over the network. env file As you know, Redis is an in-memory key-value database. Add Redis configurations, and set the cache driver to use Redis (in the. One way we can optimize a query is by reducing the amount of data we fetch from the database. In this article, we will see how does caching work with Redis in 2 simple steps: I assume you have both Laravel and Redis up and running on your local environment. ![]() $comments = $scores->lists('ratingtext') Here I some techniques that can improve your load times in your Laravel application. I attempted solving it like this in my Controller: $scores = Score::where('unit_id', $id)->where('created_at', '>', Carbon::now()->subDays(3))->get() Normally I would go about solving it like this: as I don't only want the order to be reversed, but I also want the array to be sliced, so that it just outputs the last 20 Elements of the array. Beware of N+1 issuesĬontinuing with our e-commerce example, let's say that we need to display the brand that each product belongs to.I have a Score-Table with different ratings, strings and radio-buttons. This technique is most effective in pages where you need to work with a ton of records, so you probably won't see a big change in memory usage/performance if you apply it to a page that fetches a few database records, nevertheless, it's still good to keep it in mind. This would make our query more efficient, this is especially important since the products' table would presumably contain a body column of type TEXT which could be quite large. You can reduce the amount of data by selecting only the columns you need: public function index() While doing this might seem reasonable (we are even paginating the results!), there may be a lot of information in our products' table that we don't need for a listing page (body, category id, product type, etc). 'products' => Products::query()->paginate() Our controller would look something like this: public function index() ![]() Let's say for example that we have an e-commerce website, and we want to display a list of products. The more data there is the more time it will take, but that's not all, all that data has to be stored in memory for the lifetime of the request and that can cause your server to slow down and run out of memory under heavy loads.įortunately, in Laravel, we can specify exactly the data we need. One way we can optimize a query is by reducing the amount of data we fetch from the database. Here I some techniques that can improve your load times in your Laravel application. Did you know that 1 in 4 visitors would abandon a website if it takes more than 4 seconds to load? While multiple factors can slow down a website, one common factor is inefficient database queries.Įloquent is a great tool that makes it easy to interact with the database in our Laravel applications, but sometimes we forget that what looks like a method call or property is running a database query under the hood, which might lead to slow page loads or high memory usage. You’ll now change the highlighted line to use the database query sorting method orderBy (), which orders query results at the database level, instead of simply reordering the full set of rows that is returned as an Eloquent Collection via the all () method.
