How to update only those values ​​that came in?

Question

Laravel

Tell me how in laravel to update only those values ​​that came in?

There is for example a model with such fields:
title | description | body

I know that you can update it like this:

$post = Post::find($id);
$post->title = '...';
$post->description = '...';
$post->body = '...';

$post->save();

But the trick is that if we send only the title, then the rest will be null.
If I did this from the view, I would store all the values ​​in the value of the inputs in the form and send them all, but the problem is that this is an api, and how can I make sure that only the value of the field that came in changes? I would not want to build a Christmas tree from if-else

Answer 1

$post->fill($request->validated())->save()
Of course, you either need to add fields to the fillable or use forceFill.
