CakePHP version: 1.2.0.4986alpha
I tried using findAllThreaded in my Post model to retrieve a tree of
nested posts within a thread, where my Post model is self-joined (i.e.
parent_id is the id of another Post). The problem is, findAllThreaded
only returns the ParentPost and the ChildPost, with the children array
empty. When I increase the Model::recursive value, I then get a
deeper nesting, but what if I don't know how deep the nesting goes?
Basically, how can I use findAllThreaded to retrieve the entire tree
of nested posts? (or is there an entirely different way of going
about this?)
In case it helps, here are my Post model associations:
var $hasMany = array(
'ChildPost' => array(
'className' => 'Post',
'conditions' => '',
'order' => 'created',
'limit' => '',
'foreignKey' => 'parent_id',
'dependent' => false,
'exclusive' => false,
'finderQuery' => '')
);
var $belongsTo = array(
'ParentPost' => array(
'className' => 'Post',
'conditions' => '',
'order' => '',
'foreignKey' => 'parent_id')
);
When I call $this->Post->findAllThreaded('Post.id = 1') from my
controller, the output is this:
Array
(
[0] => Array
(
[Post] => Array
(
[id] => 1
[parent_id] =>
)
[ParentPost] => Array
(
[id] =>
[parent_id] =>
)
[ChildPost] => Array
(
[0] => Array
(
[id] => 2
[parent_id] => 1
)
)
[children] => Array
(
)
)
)
However, there are about 7 other posts associated with this thread.
So, rather than setting my recursive value to 7 (which uses up all the
memory), how can I retrieve all posts from that thread using CakePHP's
features?
Thanks,
Greg
