Today, I'll show you how to list posts by categories. To do so, we will use 'containable' behavior.
Edit Category Model
file:// app/models/category.php
Replace:
var $actsAs = array('Tree');
With
var $actsAs = array('Tree','Containable');
Notice I have added the word 'Containable' in the $actsAs behavior.
Add listposts() 'action' in Category Controller
file:// app/controllers/categories_controller.php
function listposts() {
$listPosts = $this->Category->find('all');
$this->set(compact('listPosts'));
}
Create a VIEW file for showing query result.
file:// app/views/categories/listposts.ctp
<h1>Posts found by category</h1>
<?php
foreach ($listPosts as $key => $value) {
echo "<h3>" . $value["Category"]["name"] . "</h3>";
$posts = $value["Post"];
foreach ($posts as $post) {
echo "<b>" . $post["title"] . "</b>";
echo "<br />";
}
}
?>
Now point your browser to:

You should see something like this:
That's it!
