how to show records that are different from the where clause

Question

I have a query that I am doing, what I need is to show only the records that do not match the where clause.

mechanic_client

id	user_id	mechanic_id
13	31	13
16	34	1
26	61	1

users

id	name
1	lucas
31	mauricio
34	pedro
61	carlos

The user admin lucas created Pedro and Carlos, they are created both in the users table and in the mechanic_client table, so what I want is not to show Pedro and Carlos, only show the other users, but the function does not work for me it continues to show me to all users.

function index

 $users_mechanics = DB::table('mechanic_client')->get();

        foreach ($users_mechanics as $user_mechanic) {
            
            $users = User::orderBy('id', 'DESC')->with('roles')->where('id', '<>', $user_mechanic->user_id)->paginate(10);


            return [
                'pagination' => [
                    'total'         => $users->total(),
                    'current_page'  => $users->currentPage(),
                    'per_page'      => $users->perPage(),
                    'last_page'     => $users->lastPage(),
                    'from'          => $users->firstItem(),
                    'to'            => $users->lastItem(),
                ],
                'users' => $users
            ];
        
            
        } 

query return

id	name
1	lucas
31	mauricio

it should look like this

Thanks for the help..

Answer 1

MechanicClient Model
<?php

 namespace App\Model;

 use Illuminate\Database\Eloquent\Model;

class MechanicClient extends Model {

  public $table = 'mechanic_client';
  protected $primaryKey = 'id';
  protected $fillable = [
    'user_id',
    'mechanic_id',
 ];
}

In User Model

public function mechanic() {
    return $this->hasone('App\Model\MechanicClient', 'user_id', 'id');
}

And check In Controller

User::doesntHave('mechanic')->orderBy('id', 'DESC')->paginate(10);

Hope fully it will help to you.
