How much should models do? - El Forum - 02-21-2011

Hi,
I'm about to re-write a CI app of mine.
In the current version - pretty much all my models do is interact with the database. i.e. here is a typical (yet simple) example of a current model:
Code:
class User_model extends Model {
function update($data,$userid)
{
$this->db->where('userid', $userid);
$this->db->update('users', $data);
}
function get($userid)
{
$this->db->where('userid', $userid);
$q = $this->db->get('users');
if ($q->num_rows() == 1) return $q->row();
return NULL;
}
function add($data)
{
if($this->db->insert('users', $data)) return true;
return false;
}
function delete($userid)
{
$this->db->where('userid', $userid);
$this->db->delete('users');
}
}However I have read a lot that models should take care of all 'Business Logic'. I guess I'm kind of confused as to what exactly 'Business Logic' is.
For instance in my controller I currently fetch data from the model and process that data there in the controller. For example:
Code:
$user = $this->user_model->get(1);
$user->avatar = remove_ext($user->avatar) . '_small.' . get_ext($user->avatar);
$user->age = dob_to_age($user->age);I know that CI is flexible enough for me to do whatever I want wherever I want, but it seems to me that using models just for database interaction is pretty pointless. Should I be processing the 'age' and 'avatar' in my model?
Just wondering how all of you use your models.
