CI4 use model's method in view

You need to assign the complete model to a variable.

PHP Code:

<?php namespace App\Controllers;

use App\Models\ExampleModel;

class Example extends BaseController
{
    public function example()
    {
        $exampleModel = new ExampleModel();

        $data = [
            'exampleModel' => $exampleModel,
        ];

        echo view('example', $data);
    }
} 


You can then access it with $exampleModel->findbyid() in your view.
