Model initialization

[eluser]liri[/eluser]
Hey,


When loading up a model from a controller such as:

Code:

$this->load->model('model_name');

why isn't the model's constructor called? or rather, what exactly happens when that 'loading' happens?

The constuctor is called!

If you have a model the constructor will be called it
sets parent to model.

Whatever you put in the constuctor will be carried out.
You can also pass in parameters to the constuctor.

I guess you're looking for first aid here. ;-)
In controller

Code:

$this->load->model('uber_model');
$this->uber_model->make_a_cup_of_coffee($param);

In model:

Code:

function make_a_cup_of_coffee($param)
{
   echo "Coffee is coming up!";
}

Uhmm, nope.
I have:

Code:

class Menu extends Model
{
    
    public function __construct()
    {
        
        var_dump($this->modules_m->get_modules());
        
    }

and that doesn't seem to work when I load up the model.
Actually, more interesting is that now it errors on the call to the $this->modules_m->get_modules()
even though this did work just a few minutes ago... odd

A model can use the $this-> and call already loaded other models, right?

Euhrm, not quite.

I'm missing a

Code:

parent::Model();

in your constructor.

The parent constructor will take care of the creation of local class variables for every library loaded, so you can use $this->library. Note that this is only for loaded libraries, not for models!

It also doesn't work bidirectional, so if you load A, then B, you can access A from B, but not B from A, as B wasn't loaded when A was instantiated.

You're right, I totally left out the parent constructor thanks.
