Extending my own model

[eluser]msteudel[/eluser]
Hi All,

I would like to extend one of my models. (I know I could do a MY_model setup but I'm just interested in extending this one)

I have my models located in:

system/application/model

My model is

Code:

class user_model extends Model {
     // code ...
}

And I want to extend that:

e.g.

Code:

class student_model extend user_model {
     // code ...
}

But when I do that I get:

Code:

Fatal error: Class 'user_model' not found in /path/trunk/system/application/models/student_model.php

Is there a place I should add a include directive? I could autoload it in autoload file, but I don't want to always load that model all the time.

Any suggestions?

Thanks, Mark
