Laravel - Relationships - Inline Relationship Existence Queries

If you would like to query for a relationship's existence with a single, simple where condition attached to the relationship query, you may find it more convenient to use the whereRelation and whereMorphRelation methods. For example, we may query for all posts that have unapproved comments:

    use App\Models\Post;
    $posts = Post::whereRelation('comments', 'is_approved', false)->get();

Of course, like calls to the query builder's where method, you may also specify an operator:

    $posts = Post::whereRelation(
        'comments', 'created_at', '>=', now()->subHour()
