Problem between using a Model or using a Library - El Forum - 02-01-2008

What i want to do:
i want to be able to create multiple instances of a class (model or library) but as well be able to pass custom parameters (or an array of variables) to the model or library while using CI's framework.
My problem:
I seems like i can create multiple instances of a using a model, as such:
Code:
$this->load->model('Model_name', 'cat');
$this->load->model('Model_name', 'dog');
$this->load->model('Model_name', 'rat');
$this->cat->function();
$this->dog->function();
$this->rat->function();now, i want to be able pass in a third parameter, as such:
Code:
$arr_cat_specs = array('height'=>'1 foot', 'weight'=>'5lbs', 'colour'=>'white');
$this->load->model('Model_name', 'cat', $arr_cat_specs);Now if i were to use a library class, i can submit parameters with custom data, as such
Code:
$params = array('type' => 'large', 'color' => 'red');
$this->load->library('Someclass', $params);Problem between using a Model or using a Library - El Forum - 02-01-2008

Is there a specific reason you need to pass the data as part of the model load? I would think the easiest solution would be to put an init method in your model, and after load, call your init method with all the arguments you could possibly need.

ya, i suppose i could just write an init method in the model and then call the init method after.
the reason why i wanted to know was more for simplicity and efficiency.
but another line of code won't hurt i guess. haha.

Your other recourse could be to extend the core Model class as my_Model, add the extra argument to my_Model constructor but make sure to call parent::Model with the expected arguments.
Then it's simply a matter of writing your own models to extend my_Model rather than Model.

Code:
$this->load->model('Model_name');
$cat = new Model_name($cat_features);
$dog = new Model_name($dog_features);
$rat = new Model_name($rat_features);Libraries can be loaded and sub-classed with exactly the same method

What exactly is that doing. I was also looking for a method to pass parameters into models. I think it's bizarre how that was left out.

It's creating new model objects from the loaded class, and passing a parameter to the constructor. That is what you were looking for?

Might as well just manually include it because it already instantiates it and attaches to the super object using your method.

Ummm... It's not my method, its standard OOP coding practice. It's called instantiation.

but aren't you wasting resources by using the $this->load->model('Model_name'); method.
When you won't use the object that's attached to the ci super object.
