How to like on Laravel?

Question

Laravel

There are articles. You need to add the ability to like or dislike.
I am aware of this solution:

// Used by model App\Like

Schema::create('likes', function (Blueprint $table) {
    $table->increments('id');
    $table->unsignedInteger('likeable_id');
    $table->string('likeable_type');
    $table->unsignedInteger('user_id');
    $table->timestamps();
});


// Post & Comment model

public function likes()
{
    return $this->morphMany('App\Like', 'likeable');
}

// Then you can do something like 
<p>
  This post has {{ $posts->likes()->count() }} likes
</p>

But is this the right decision? This table can get incredibly large, and I'm worried about that. I don't know how the site will behave.

Answer 1

As it becomes incredibly large and slow, then you can easily and simply separate the problematic entity. Those. solve the problem when it appears, not in advance. This is if it appears. In the meantime, you can do it as in the example, just remove likes in the trait to the same methods with likes (write / delete, etc.) so that the code is not duplicated, instead

$table->unsignedInteger('likeable_id');
$table->string('likeable_type');

write AND count of likes can be written and incremented in the database so that no requests are made
$table->morphs('likeable');

Answer 2

Incredibly large is how many?) several million records? It's about nothing. It is only necessary to arrange the indexes correctly.
I just don't see any dislikes.
