How to Disable Primary Key & Auto Increment in Laravel?

To disable the primary key and auto increment in the laravel, laravel provides us $primaryKey and $incrementing variable in the model.

Here is how to do it in the model:

<?php
  
namespace App\Models;
  
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
  
class Article extends Model
{
    use HasFactory;
  

    protected $primaryKey = null;
  

    public $incrementing = false;
  

    protected $fillable = [
        'title', 'content','category'
    ];
}

In the above code, we have protected $primaryKey = null variable to disable primary key and public $incrementing = false; in order to disable the autoincrementing.

So now if we add the article, the primary key and auto increment will not get updated.

Conclusion:

Great, so in the above tutorial, you have learned how to disable primary key and auto increment in laravel Model.
