Question

i’ve a question about atk4 MVCgrid, my db table doesn’t have a field called “id” my primary key is id_material, i don’t be able to change idfield, my SQL contain a file id that doesnt’ exist so it fail.
How i can change default id primary key field (id) with my real primary key?

My simple code:

class Model_Material  extends Model_Table 
{
    public $entity_code='material';
    public $table_alias='p';
    function defineFields(){
        parent::defineFields();
        $this->addField('id_material');
        $this->addField('material');
    }
}

Thank’s

All you need to do is to create an alias:

$this->getField('id')->calculated(true);

function calculate_id(){
    return 'id_material';
}

You would have more difficulties with foreign keys. You might want to keep watch on 4.2 release, which will have more flexibility.
