Body
It's considered poor form to use <code>var $uses</code> in CakePHP 1.3+. It's been replaced by App::import (see below) Given you have a Users controller with User model, and a Comments controller with Comment model. The accepted patterns are: Using Associations This is your best bet if the models can be logically associated. <pre><code>// models/user.php Class User extends AppModel { public $hasMany = array('Comment'); } // controllers/users_controller.php Class UsersController extends AppController { function allComments() { $this->User->Comment->find('all'); // You can use this across multiple models (e.g. $this->User->Comment->NestedComment->find('all'); } } </code></pre> Instantiating the model object This will load your model file, add the instance to CakePHP's object map, and returns the instance. <pre><code>// models/user.php Class User extends AppModel {} // models/comment.php Class Comment extends AppModel {} // controllers/users_controller.php Class UsersController extends AppController { function allComments() { $Comments =& ClassRegistry::init('Comment'); $Comments->find('all'); } } </code></pre> Using $this->loadModel Internally this uses ClassRegistry::init, then also adds the model as a property of the controller. <pre><code>// models/user.php Class User extends AppModel {} // models/comment.php Class Comment extends AppModel {} // controllers/users_controller.php Class UsersController extends AppController { function allComments() { $this->loadModel('Comment'); $this->Comment->find('all'); // using load model allows you to access it via $this->Model } } </code></pre> App::import This is really just the CakePHP way of requiring a file. You'll still need to instantiate the object. <pre><code>// models/user.php Class User extends AppModel {} // models/comment.php Class Comment extends AppModel {} // controllers/users_controller.php App::import('Model', 'Comment'); Class UsersController extends AppController { function allComments() { $Comment = new Comment(); $Comment->find('all'); } } </code></pre> I hope this helps. Edit: If you want to use the model object globally within the controller, you can use any of these patterns I specified within your <code>beforeFilter()</code>.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
