Can a model use another model? - El Forum - 01-13-2010

I have a model class that make all the data base operations, but i want that model to use another class and put all the data from the data base in some variables, then, i just send to the controller an array of mi object.
for example:
this is the class
Code:
<?php
class Person extends Model{
private $name;
private $lastname;
private $password;
public function getName()
{
return $this->name;
}
function setName($data)
{
$this->name = $data;
}
public function getLastname()
{
return $this->lastname;
}
public function setLastname($data)
{
$this->lastname = $data;
}
public function getPassword()
{
return $this->password;
}
public function setPassword($data)
{
$this->password = $data;
}
}
?>and this is the model
Code:
<?php
class Formulario_model extends Model{
function obtener_usuario()
{
$this->db->where('idpersona','1');
$query = $this->db->get('persona');
if($query->num_rows() > 0){
foreach($query->result() as $row){
$this->load->model('person');
$this->person->setName($row->name);
}
return $data;
}
}
}
?>if i do this i get this error
Fatal error: Call to a member function setName() on a non-object in C:\Aplicaciones\formulario\system\application\models\formulario_model.php on line 13
how can i solve this?
thanks

Because the model has not been previously loaded, it's not yet a part of the CI object, so it is never copied to your current model. You'll need to go through the CI object to do so
Code:
$ci =& get_instance();
$ci->load->model('other_model');
$ci->other_model->call_method();Can a model use another model? - El Forum - 01-13-2010

I had once the same problem and if If I remember right, I got I it working by just loading (here I use Your model names) the Person model before the Formulario_model.
