Re: Model with self association: how do I reference associated field from Child?

Thank you cricket.

From what you've shared, I've been learning a lot about the Containable behavior, including limiting the fields displayed. That is very helpful. I was using:

'contain' => array(

  'Passage' => array(

    'fields' => array(

      'Passage.id',

      'Passage.ref_abbr')

    ),

  'ParentTopic' => array(

    'Passage'

    ),

   'ChildTopic' => array(

    'Passage'

   )

)

I still cannot get it to work with ChildTopic -- you're right that it does not recognize it as an associated model (though it does not give that error re: ParentTopic). What exactly is 'ParentTopic' => array('Passage') "saying in SQL" -- something like "make topics have a LEFT JOIN to ParentTopic and a LEFT JOIN to Passage"? Even though I'm getting a SQL errror, I can see that it is trying to do something like that, but ChildTopic is not even included in the SQL error.

One question, before I go too far down the wrong track: what are doing when you wrote, above,  $this->alias.'.id' => $id ? When I include that, die(debug($data)); returns null. So, I tried, instead, $this->id => $id -- which returns a SQL error. I obviously do not understand something about use of alias.

Again, thank you.
