session library inside of models?

Hm.
OK, code looks fine. Error message means $this->session is not resolving as expected in your model. Here's a couple of thoughts:

Try setting and retrieving the session 'user_id' in the controller that includes the model in question. Just making sure the session library itself is loading/working ok.

Can your model use other libraries? Perhaps try sending an email.

Does your model extend Model and start with a capital letter, as per user guide? That can be an easy one to miss

Code:

class Abc_model extends Model {

  function Abc_model() {
    parent::Model();
  }
...

If none of those sheds any light, I'm not sure where to try next. Even those are a shot in the dark.
