Mutators actually format the attributes even before storing them in the database. The syntax of this function is where setNameAttribute().

Name is the camel-cased column that you want to access.

A one-time seeder need to be created with dummy data directly. This will help us to reuse when the project needs to be deployed for the first time. A seeder can be developed after table migration. All the classes present in the seed need to be placed in one directory  

How the database seeder is created?

In order to develop a seeder, you need to run make:seeder Artisan command. The seeders developed using Laravel need to be places in database/seeds directory:

Queues are quite helpful in laravel when it comes to asynchronous work or taking jobs and forwarding them in order to be performed by some other processes. It also proves to be helpful for making time-consuming API calls, so that we do not have to make our user wait before the next page is provided.

The best part of using queues is there is no need to work on the lines given on a similar server like your application. In case, your work involves excessive computations, then suddenly there is no need to take any risk for drawing down or taking down the web server

How the take() and skip() options are used in the Laravel Query?

Both the take() and skip() methods are used in order to limit the results in query. Moreover, skip() is preferred for skipping the result numbers, while, take() is for obtaining the result numbers from query.

$posts = DB::table(‘blog’)->skip(5)->take(10)->get();

// skip first 5 records

// get 10 records after 5

How the real time sitemap.xml file can be developed in Laravel?

Well, we can develop web pages of websites in order to tell search engines like Yahoo, Bing etc as well as Google about the site contents. The web crawlers present in the search engines access this file to crawl the sites more intelligently.

Some of the steps are mentioned below for creating the real time sitemap.xml file. These steps can also be used for developing dynamic XML files.

  • You need to develop a route for this in the routes/web.phpfile
    For instance,
    Route::get(‘sitemap.xml’, ‘SitemapController@index’)->name(‘sitemapxml’);
  • A SitemapController.php can be developed with the help of an artisan command php artisan make:controller SitemapController

This code can be used in the controller

public function index() {
$page = Page::where(‘status’, ‘=’, 1)->get();
return response()->view(‘sitemap_xml’, [‘page’ => $page])->header(‘Content-Type’, ‘text/xml’);

Now, you need to develop a view file in the resources/view/sitemap_xml.blade.phpfile using this code

Enter this code in the view file developed by you

<?php echo ‘<?xml version=”1.0″ encoding=”UTF-8″?>’; ?>
<urlset xmlns=”″
@foreach ($page as $post)
<loc>{{ url($post->page_slug) }}</loc>
<lastmod>{{ $post->updated_at->tz(‘UTC’)->toAtomString() }}</lastmod>
