Question

I’m attempting to use a Model but I get a fatal error so I assume it doesn’t autoload properly.

ErrorException [ Fatal Error ]: Class
‘Properties_Model’ not found

The offending controller line:

$properties = new Properties_Model;

The model:

class Properties_Model extends Model
{
    public function __construct()
    {
          parent::__construct();
    }

}

I also put the class in three different locations hoping one would work, all there failed.
They are:
application/classes/model
application/model
application/models

What am I missing?

Answer 1

Ah, I got this question emailed directly to me (via my website’s contact form)!

Here is what I responded with (for the benefit of other people which may run into this problem).

The correct location of a model named
properties is

application/classes/model/properties.php

and the class definition would be as
follows

class Model_Properties extends Model { }

Think of the underscore above as the
directory separator. That is, if you
replaced the underscore with a / you
would have: ‘model/properties’, which
will be your file under application/classes.

To load the model from a controller,
you can use PHP’s standard new
operator or do what I prefer, which is

$propertiesModel = Model::factory('Properties');

I’m not 100% why I prefer this way…
but it works for me 🙂
