Extending Datamapper

[eluser]WanWizard[/eluser]
Your DataMapperExtra class can't have a constructor. The current Datamapper constructor checks if the class loaded it 'Datamapper' (on which it does some setup) or not, in which case it is assumed to be a model.

To work around it, you can try

Code:

<?php
include "datamapper.php";

class DatamapperExtra extends Datamapper
{
}

and store this in application/libraries/datamapperextra.php.

Additionally, you need to modify datamapper.php:

Code:

//change
        $is_dmz = $this_class == 'datamapper';
// to
        $is_dmz = $this_class == 'datamapperextra';

After this, your models should be able to extend Datamapperextra instead of Datamapper.

Currently I don't see another option.
