Gm,
Is it possible to auto a model and assign it a different object name?
In a controller I would do this:
Code: $this->load->model('Model_name', 'fubar');
In autoload the second param would be another model name.
Code: $autoload['model'] = array('Common');
Thank you.

That's a very good question, and unfortunately there's no way to do that. As far as I can see, this leaves two options.
Option 1 - You load a helper file or something similar, which will reassign the autoloaded model to a name of your liking. Perhaps something like this:
Code: function reassign_model_names()
{
$CI =& get_instance();
$db = $CI->original_model;
unset($CI->original_model);
$CI->new_model_name =& $db;
}
...But that's fugly, and clunky.
Option 2 - Override the Loader library with your own method:
./system/application/libraries/MY_Loader.php
# CODE MOVED TO http://ellislab.com/forums/viewthread/110977/#560058
The code above is untested, but should allow you to use an array in your autoloader:
Code: $autoload['libraries'] = array('database', array('email', NULL, 'email2'), 'session');
The arguments in the array should be just as they would be if you were to call $this->load->library() directly:
Code: array($library_name, $params, $object_name)
Hope this helps.

Ah nuts. I got lost there, and this will only allow you to load libraries in that fashion, not models... Sorry. I'll go back to the drawing board soon.

Try this method in a CI_Loader class extension
Code: /* autoload models */
if (isset($autoload['model']))
{
foreach ($autoload['model'] as $model => $alias)
{
(is_numeric($model)) ? $this->model($alias) : $this->model($model, $alias);
}
}

OK, I started over, and I noticed that the model and library loader methods worked a lot more differently to each other than I'd thought, so I decided to override both the model() and library() methods in the loader class. I figured that you might as well allow the same behaviour with libraries too, although you are free to delete that method if you wish. I also think I might have spotted a potential bug in the library loader, but I need to look into that a bit further.
./system/application/libraries/MY_Loader.php
Code: <?php
class MY_Loader extends CI_Loader {
function library($library = '', $params = NULL, $object_name = NULL)
{
if ($library == '')
{
return FALSE;
}
if ( ! is_null($params) AND ! is_array($params))
{
$params = NULL;
}
if (is_array($library))
{
foreach ($library as $class)
{
# START EDIT
if (is_array($class)
{
list($_class, $_params, $_object_name) = $class;
$this->_ci_load_class($_class, $params, $_object_name);
}
else
{
# Is this a bug? CI would try to use the same paramters and
# object names on all libraries in the array??
$this->_ci_load_class($class, $params, $object_name);
}
# END EDIT
}
}
else
{
$this->_ci_load_class($library, $params, $object_name);
}
$this->_ci_assign_to_models();
}
function model($model, $name = '', $db_conn = FALSE)
{
if (is_array($model))
{
foreach($model as $babe)
{
# START EDIT
if (is_array($babe))
{
if (isset($babe[0]))
{
$model = $babe[0];
$name = (isset($babe[1])) ? $babe[1] : NULL;
$db_conn = (isset($babe[2])) ? $babe[2] : FALSE;
$this->model($model, $name, $db_conn);
}
}
else
{
$this->model($babe);
}
# END EDIT
}
return;
}
if ($model == '')
{
return;
}
// Is the model in a sub-folder? If so, parse out the filename and path.
if (strpos($model, '/') === FALSE)
{
$path = '';
}
else
{
$x = explode('/', $model);
$model = end($x);
unset($x[count($x)-1]);
$path = implode('/', $x).'/';
}
if ($name == '')
{
$name = $model;
}
if (in_array($name, $this->_ci_models, TRUE))
{
return;
}
$CI =& get_instance();
if (isset($CI->$name))
{
show_error('The model name you are loading is the name of a resource that is already being used: '.$name);
}
$model = strtolower($model);
if ( ! file_exists(APPPATH.'models/'.$path.$model.EXT))
{
show_error('Unable to locate the model you have specified: '.$model);
}
if ($db_conn !== FALSE AND ! class_exists('CI_DB'))
{
if ($db_conn === TRUE)
$db_conn = '';
$CI->load->database($db_conn, FALSE, TRUE);
}
if ( ! class_exists('Model'))
{
load_class('Model', FALSE);
}
require_once(APPPATH.'models/'.$path.$model.EXT);
$model = ucfirst($model);
$CI->$name = new $model();
$CI->$name->_assign_libraries();
$this->_ci_models[] = $name;
}
}

Close!
Line 37 needs ")"
and I get this error:
Quote:Message: Missing argument 1 for Dealer_model: ealer_model(), called in W:\www\s\system\application\libraries\FW_Loader.php on line 137 and defined
On this bit of code:
Code: $CI->$name = new $model();
Off of this auto load:
Code: $autoload['model'] = array(array('dealer_model', NULL, 'dealer'));
[eluser]TheFuzzy0ne[/eluser]
You are using the syntax for loading a library. In your autoload.php file, to load a model you'd need to do something like this:
Code: $autoload['model'] = array(array('dealer_model', 'dealer'));
[eluser]RJ[/eluser]
This is the method in my main controller calling the deal model and passing $dealer from the uri. Not passing right for some reason
Code: function device($dealer = '999')
{
$this->benchmark->mark('code_start');
// start benchmarking
$this->dealer($dealer); // passes db info to dealer library for processing
$this->dealer->dealer($dealer); // tried this as well
This is my dealer_model:
Code: class Dealer_model extends Model {
var $dealer = "";
var $vars = "";
#--------------------------------------------------------------------------
# Controller
#--------------------------------------------------------------------------
function Dealer_model($dealer)
{
// Call the Model constructor
parent::Model;
print_r($dealer);
// submit log entry
log_message('debug', "Dealer Class Initialized");
// on screen php error display
ini_set('display_errors', 1);
// use dealer var to grab info from db, set $vars
$this->vars = $this->grab_vars($dealer);
// add dealer info to session
$this->session->set_userdata('dealer',$this->vars);
// submit log entry
log_message('debug', "Dealer routines successfully run");
}

I've just borked my Aptana install, so I'm reinstalling it now. I'll do some debugging shortly.
[eluser]RJ[/eluser]
Ok. So I can access the model with this:
Code: $this->dealer->dealer_model($dealer);
Not entirely sure why I need to name the constructor for my dealer_model, but it doesnt work without that.
I can't get my controller to send the URI data to the model; had a similar issue with a library, fixed it, but i decided to use a model rather than a library, back at the same problem.
Controller:
Code: function Shop()
{
parent::Controller();
$this->output->enable_profiler(TRUE); // debug onscreen
ini_set('display_errors', 1); // on screen php error display
}
/*
#--------------------------------------------------------------------------
# METHOD: Device Sub-Controller
#--------------------------------------------------------------------------
|
| http://findwhere.com/s/shop/device
| this is the Method that runs the above URL
*/
function device($dealer = '999')
{
$this->benchmark->mark('code_start');
// start benchmarking
$this->dealer->dealer_model($dealer); // passes db info to dealer library for processing
Dealer_model:
Code: class Dealer_model extends Model {
var $dealer = "";
var $vars = "";
#--------------------------------------------------------------------------
# Controller
#--------------------------------------------------------------------------
function Dealer_model($dealer)
{
// Call the Model constructor
parent::Model();
print_r($dealer);
// submit log entry
log_message('debug', "Dealer Class Initialized");
// on screen php error display
ini_set('display_errors', 1);
// use dealer var to grab info from db, set $vars
$this->vars = $this->grab_vars($dealer);
// add dealer info to session
$this->session->set_userdata('dealer',$this->vars);
// submit log entry
log_message('debug', "Dealer routines successfully run");
}
PHP ERRORS:
Code: list($model, $name, $db_conn) = $babe;
Error: Quote:Severity: Notice --> Undefined offset: 2 W:\www\s\system\application\libraries\FW_Loader.php 67
there are more, but those should be solved once the passing from controller to model is worked out.
