Loading Models - El Forum - 10-24-2008

I have a couple models for this application and just noticed I needed to call one of the functions from another model...
dbs_model
Code:
class DBS_Model extends Model {
function DBS_Model()
{
parent::Model();
$this->load->model('account_model');
}account_model
Code:
class Account_Model extends Model {
function Account_Model()
{
parent::Model();
$this->load->model('dbs_model');
}Do these conflict each other as each one calls the other?
I have tried to autoload all my models in the config, but the one function within the dbs_model fails with the following error:
Code:
Severity: Notice
Message: Undefined property: Account_Model::$dbs_model
Filename: models/account_model.php
Line Number: 268
Fatal error: Call to a member function Backup() on a non-objectI know this may look confusing but I hit a dead end here and I not sure why I simple just couldn't load the dbs_model and call its function within the account_model..
If I leave the load dbs_model in the constructor, one of the functions with the account model actually prompts me to download a binary file... and as soon as I comment out the load dbs_model it works fine...
Help!!

From what I read, you shouldn't load models within models, they should be loaded from the controller... so I will see if I can fix my coding to leave out any models that load more models.... but I really need some help here.

I also would suggest you need to redesign it somehow. Two classes (or in that case models) who associate each other, that's a weird constellation...

So lets say I have this:
Code:
class Account extends Controller {
function Account()
{
parent::Controller();
$this->load->model('account_model');
$this->load->model('hosting_model');
$this->load->model('dbs_model');
}
}So I should be able to call any of the dbs_model function from within this controller.
I think my problem is that I am trying to call dbs_model->Backup() within the account_model itself. I think I get it but just want to make sure.

[quote author="rob897" date="1225138286"]Can I assume that all the functions within the other models loaded are available throughout this entire controller?[/quote]
Jep, that's right.

So then with this controller
Code:
<?php
class DBS extends Controller {
function DBS()
{
parent::Controller();
$this->load->model('dbs_model');
$this->load->model('account_model');
$this->load->model('hosting_model');
}
function Edit()
{
$this->dbs_model->Edit();
}
function Delete()
{
$this->dbs_model->Delete();
}
function Create()
{
$this->dbs_model->Create();
}
function Backup()
{
$this->dbs_model->Backup($database='',$domain='',$uid='');
}
function Update()
{
$this->dbs_model->Update();
}
}Within the "accounts_model" class there are functions that return account information, I think I am accessing these directly from the model and not the controller so for instance, I have in the dbs_model something that returns:
Code:
$this->account_model->SearchAccounts($domain);
