you could execute a delete call from the controller.
i assume your delete action is in the posts controller and it hasMany
('Comments');
function delete ($id = null)
{
//contain the post model (always good practice to limit extra db
calls .. or use recursive attribute in conditions
$this->Post->Behaviors->attach('Containable');
$this->Post->contain();
//if we find a Post with the passed ID (please also include logic to
authorize this action)
if ($this->Post->find('first', array('conditions'=>array('Post.id'=>
$id))))
{
//delete post with passed id
$this->Post->delete($id);
//delete all comments with fk post_id that equals $id
$this->Post->Comment->deleteAll(array(‘Comment.post_id’ => $id));
}
hope this helps
