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.
