Call Model function from Controller

#1
While I know the concept of MVC but I am not sure if I am doing this the most 'efficient' way
I have sql function in Model, I wan call it from Controller to pass it to View
Below is how I do the 'flow'.
Any shorter method or there a better way of doing?

Controller
PHP Code:
$participants = new ParticipantModel();
$data['participants_details'] = $participants ->participants_total();

echo view('login', $data); 


Model
PHP Code:
<?php namespace App\Models;

use 
CodeIgniter\Model;

class 
ParticipantModel extends Model
{
public function 
participants_total() {
// (some sql query here and return result)
}

That's the right way to do it.

Well, I'd guess that too. But it doesn't work! I've spent the whole morning trying to get basic stuff like this to work ... but CI 4 seems to have broken PHP itself, or something.

You need to tell your model what table to use, most of the CodeIgniter Model parameters
need to be setup in your model. I would open the system/Model.php and take a look at all
the parameters it has to offer.

PHP Code:
<?php namespace App\Models;

use 
CodeIgniter\Model;

class 
ParticipantModel extends Model
{
    /**
     * -------------------------------------------------------------------
     * Class properties go here.
     * -------------------------------------------------------------------
     *
     * public, private, protected, static and const.
     */


    /**
     * Name of database table
     *
     * @var string
     */
    protected $table 'your_table_name';

    public function participants_total()
    {
        // (some sql query here and return result)
    }


With that you should be able to use any of the CodeIgniter Model's methods.

Yes, I managed to make a completely dynamic API ResourceController passing in all these properties as config settings. That way I avoid having a Controller AND a Model per resource. I just config them all in a single file ... as all the basic CRUD methods are the same across a ResouceController. Will see if this bite me later down the road ... but pretty confident for now ; ).
