How can I self join a model? I want the Topic Model to have many child
topics or be the child of one topic. I am trying to use:
<?php
class Topic extends AppModel {
var $name = 'Topic';
var $hasMany = array(
'Topic' => array(
'className' => 'Topic',
'foreignKey' => 'parent_id'
)
);
var $belongsTo = array(
'Topic' => array(
'className' => 'Topic',
'foreignKey' => 'parent_id'
)
);
}
?>
But I get the following error in the index view:
Warning (512): SQL Error: 1066: Not unique table/alias: 'Topic'
Thanks for the help.
