I've added parent_id to tweets as a means to include tweets as comments too.
I've added a parent() and children() method to the Tweet model

    public function children()
    {
        return $this->hasMany('App\Tweet', 'parent_id')->with('children');
    }

But when I add ->withCount('children') to the timeline() method it foobar's the ->withLikes() method. instead of a number for likes & dislikes I get json string of the likes array instead.
[{"id":1,"user_id":1,"tweet_id":50,"liked":1,"created_at":"2020-10-12T20:24:10.000000Z","updated_at":"2020-10-12T20:27:00.000000Z"},{"id":3,"user_id":2,"tweet_id":50,"liked":1,"created_at":"2020-10-12T20:24:29.000000Z","updated_at":"2020-10-12T20:24:29.000000Z"}]

My questions is, why does this happen? is it someinthg in the Likable trait that doesn't like the withCount or the possiblitiy is nesting? or other?

I know and appreiacite it is a little off-topic so any help would be cool.

This example code produces one sql extra query for each tweet:

select * from "users" where "users"."id" = '1' limit 1

So for many tweets this will kill any database. I understand that this is just a "basic example", but I would say that avoiding unneccessary db queries belongs to the basic teachings that any new developer should learn - it is really important to not teach people wrong things, they will carry on with that for very long and it will hurt them eventually.

It would be great if you would like to add some information to your tutorial about how to cache queries or avoid them - also it will be a good thing for all the db admins around the world to produce new developers that do not produce code like this :) - thank you very much!

In the "Build a Like/Dislike system" episode 67 of the series, in 22:23 timestamp, we start including the "like" and "dislike" buttons and im getting a Call to a member function where() on null this happens after I implement this on the _tweet.blade.php blade file

<div class="flex items-center {{ $tweet->isDislikedBy( current_user() ) ? 'text-blue-500' : 'text-gray-500' }}">

The error is actually being returned in line 4:

1.    public function isDislikedBy(User $user)
2.    {
3.        return (bool) $user->likes
4.            ->where('tweet_id', $this->id) 
5.            ->where('liked', false)
6.            ->count();
7.    }

How can I start knowing what's going on in or out from the isDislikedBy() ? What im thinking is that I should be back-engineering the source of that where function because what's inside of it, it's returning null. I noticed jeffrey doesn't ever references a Model, like for example, this: use App\Like and that happens in most of the files, where as I have had to do that in some Models. I know he's on Laravel 6 and Im wondering if in Laravel 8, the reason why it's returning null is because an endpoint somewhere isn't being referenced. Thanks! Awesome project.

Hi,
I'm finding I can't login following registration. would this be a know issues?

Install

Login > "These credentials do not match our records."

is the validation and/or hasing correct?
*Needless to say that this user is indeed within the database and I am using the correct details.
