How do i restrict the list in a referenced model in ATK4

Question

I have a model called Task defined like this (fields not relevent to question removed)

  <?php
  class Model_Task extends Model_Table {
   public $entity_code='vscrum_task';
   public $table_alias='tk';

   function init(){
     parent::init();

  // debug causes error in Ajax in ATK v4.1.1
  // $this->debug(true);
     $this->addField('id')->system(true)->visible(false); 
     $this->addField('task_desc')->mandatory(true)->visible(true);
     $this->addField('tasktype_id')->mandatory(true)->refModel('Model_TaskType');
     $this->addField('team_id')->system(true)->visible(false);

and the refModel tasktype is defined like this (fields not relevent to question removed)

<?php
    class Model_TaskType extends Model_Table {
      public $entity_code='vscrum_tasktype';
      public $table_alias='ty';

      function init(){
     parent::init();

         $this->addField('id')->mandatory(true);
         $this->addField('name')->mandatory(true);
         $this->addField('team_id');

        }   
     }

I have a CRUD which is based on task and is now (thanks to help from Jancha and Romans on stackoverflow) is working fine.

I want to limit the options in the drop down for TaskType to only those tasktypes defined for the user's team. I tried putting an addCondition in the TaskType Model referencing a session variable i had previously memorized

  $this->addCondition('team_id',$p->api->recall('team_id'));

and also using a direct call to a value for the logged in use

  $this->addCondition('team_id',$p->api->auth->get('team_id'));

but this results in showing the Tasktype fine in the Grid

but leaves it empty for both Edit and Add in the Ajax dialog.

If i remove the addCondition line from the TaskType Model, it shows all values in the list but i will always want this restricted to a subset.

As this is the referred Model and not the Model that the CRUD is based on, any suggestions on how i get this to work as expected ?

I tried Roman's suggestion of having a model which is the TaskType and a new model extended from that which is the TaskType_Team with the addCondition in it like this

class Model_TaskType_Team extends Model_TaskType { function init(){ parent::init();

    $this->addCondition('team_id',$p->api->auth->get('team_id'));
  }

for which i needed to create a subdirectory undel Model called TaskType otherwise it didnt find the new Model but the end result is the same. I think this is related to another issue i previously had where the Ajax dialog loses access to $p->api and so doesnt display the restriction (and this is why it works fine for the grid on the same page as that isnt in an ajax dialog but i dont want to use a stickyGet to resolve this for security (dont want to be able to modify the URL to see other teams data) and session variables ($p->auth->memorise and $p->auth->recall) also dont seem work in this case - any further suggestions ?

Remember that you can extend your models like that. In fact, this is very often used in larger projects.

class Model_TaskType_Team extends Model_TaskType {
    function init(){
        parent::init();
        $this->addCondition('team_id',$this->api->auth->get('team_id'));
    }
}
