error instance controller after loading a model

[eluser]jorgeakanieves[/eluser]
I have modified codeigniter code doing a schema views.

Code:

a) execute controller:
admin.php
$this->load->library('users');

b) load a model from library...
users.php
$this->CI->load->model("model_users");

c)  return to controller and send the view to schema controller
admin.php
parent::sendContent($view);

d) from schema class load other controllers...
$view = $this->load->controller('header');

here is when i get the error because i try in controller function to do:

Code:

$obj =& new $name(); //new header()

and I get the error:

Code:

Undefined property: CI_header::$model_users
Fatal error: Call to a member function _assign_libraries() on a non-object in...Loader.php on line 1085

If I set to null the

Code:

$this->_ci_models

I resolve the problem... Why??

I supose I can´t use the model_users model after this....

It resolves the problem because you no longer enter the loop in the loader.

The problem is quite clearly that you're trying to access $this->model_users from an object that has no model_users class variable. If you define model_users in the users controller it won't suddenly be copied over when you instantiate another one. $this is a reference to the current object.

Then , it seems that this solution is a good practice?

Check out Modular Extensions HMVC, in my signature, it may help.

I´ve seen it. I think the problem is when I load the model...

Code:

//at the end of the model function your code is:
        
// instanciate and iniciate model on ci instance
$this->_me->$_alias =& new $model();
// assign libraries out of model class for the model class
$this->_assign_libraries_to($this->_me->$_alias);

// at the end of the function model my code is:
// instanciate and iniciate model on ci instance
$CI->$name = new $model();
// assign libraries on model class
$CI->$name->_assign_libraries();
// save models on CI
$this->_ci_models[] = $name;

you don´t save the model class object, isn´t it? is it the only difference?

Besides you assign libraries outside the model class but I think it´s insignificant.
