It's in the right place but you have amended it.
You are populating a variable called $categories - you normally do that for a
list. You are using find 'all' and then restricting it with a condition. Use
find first instead (that was my original mistake). Your $category variable is
being populated with a read. On the assumption that you want the variable
$category to be populated with 'this' category, do this (then check the
variable $category in the view - die(debug($category)); is good for that):
<?php
class CategoriesController extends AppController {
var $name = 'Categories';
function index() {
$this->Category->recursive = 0;
$this->set('categories', $this->paginate());
}
function view($id = null) {
if (!$id) {
$this->Session->setFlash(__('Invalid category', true));
$this->redirect(array('action' => 'index'));
}
$this->Session->write("category_id", $this->_categoryId()); //
why are you doing this?
// this->set('category', $this->Category->read(null, $id)); -
redundant
$this->set(
'category',
$this->Category->find(
'first',
array(
'conditions' => array('Category.id' =>
$id),
'Contain' => array(
'Post' => array(
'User' => array(
'User.id',
'User.name'
)
)
)
)
)
);
}
