Table of Contents
What does it do? It separates domain logic from the presentation, isolating application logic.
A model is generally an access point to the database, and more specifically, to a certain table in the database. By default, each model uses the table who's name is plural of its own, i.e. a 'User' model uses the 'users' table. Models can also contain data validation rules, association information, and methods specific to the table it uses. Here's what a simple User model might look like in Cake:
Example 6.1. Example User Model, saved in /app/models/user.php
<?php
//AppModel gives you all of Cake's Model functionality
class User extends AppModel
{
// Its always good practice to include this variable.
var $name = 'User';
// This is used for validation, see Chapter "Data Validation".
var $validate = array();
// You can also define associations.
// See section 6.3 for more information.
var $hasMany = array('Image' =>
array('className' => 'Image')
);
// You can also include your own functions:
function makeInactive($uid)
{
//Put your own logic here...
}
}
?>
