Hello Developer, In this blog, I will teach you the relationship withExist Method in Queries. Some days ago, Taylor Otwell merged withExists method to Queries Relationships in Laravel 8.x.

In this blog, you can learn how to use the withExists Method in Your Eloquent Query. You can see the merged request from this link. Let's now see how to use this method:

$users = User::withExists('posts')->get();
$isAuthor = $user->posts_exists;

The column name can also be aliased:

$users = User::withExists('posts as is_author')->get();
$isAuthor = $user->is_author;

Relations can filter relations, and multiple relation existences can be fetched at the same time:

$users = User::withExists([
        'posts as is_author',
        'posts as is_tech_author' => function ($query) {
            return $query->where('category', 'tech');

Thank you for reading this blog.
