Newbie question : can I load a model within a model ?

[eluser]Unknown[/eluser]
Hi

I'm trying CodeIgniter on a small project.
I need to make an object by mixing datas from several tables. I've made a Model (ex : model1, model2, model3) for each table and I would like to use model2 and model3 in model1.
Is it possible ?
Is there another approach to do that ?

Thanks in advance,

Swdes

yes, if loaded in models constructor.. if outside the constructor you have to get the CI object instance, there was a discussion on this a while back i'll dig out the thread and post it here

1)you will find my simple example of loading in the constructor.

2)you will find mpress's rather clever solution of putting:

Code:

$this->_ci_assign_to_models();

in the model method of loader.php, which enables you to load a model in the normal way outside the constructor.

3)you will find codeofficers nifty method of getting the CI (Code Igniter) object so you can load a model outside the constructor:

[quote author="CodeOfficer" date="1193827453"]this works great for me:

Code:

class MyModel extends Model
{
    private $CI;
    
    function MyModel()
    {
        parent::Model();
        $this->CI =& get_instance();    
    }
    
    function whatever()
    {
        $this->CI->load->model('model1');    
        $this->CI->model1->method1();
    }
    
    function woot()
    {
        $this->CI->load->model('model2');    
        $this->CI->model2->method2();    
    }
}

so you have three valid ways of doing it
