How to set eloquent relation data?

[nahid]

Suppose I have Model Post and every post has many Comment. So how to set index for this Post with its Comments?

You could bind to a model event such as updated.

Then iterate through the relations:

$post->comments->each(function ($comment) {
    $comment->updateIndex();
});

I would do this asynchronously through a queue.
