Currently it is not possible yet to use the CodeIgniter's models. We are developing to have a new package called "codeigniter". The idea is that in your report you add following line:

class MyReport
{
    use \koolreport\codeigniter\Friendship;
    ...
}

By this settings, you will be able to use the default database settings in CodeIgniter and other features such as model.

The same concept will be applied to other common PHP Frameworks as well such as Laravel or Yii2.

Do you like the ideas? If you want we can send you the alpha version when we are ready.

For now, you may download the QueryBuilder which is totally free. The way to use QueryBuilder is very convenient and sometime I like it more than object model, for example:

$this->src(
    DB::table("orders")->select("productName","price")
)
...

Hope that helps.

Sure, we will keep you update!

Just to let you know that the CodeIgniter has been released. Please download the package and the latest version of KoolReport.
