Model layer

Model of Framework class undertake major processing operations as well as the functionality of the website. Model is the only class in the MVC 3 class direct access to the database to ensure the maintenance and expansion of the MVC pattern.

Because it is built on object-oriented model should each be designed as one PHP class and placed in the folder /models/. The Model can gather in groups for easier use Model, inheritance and maintenance. In Admin Panel Code Generator function, helps you from a table in the database, generate a model class with methods and attributes essential to be able to use right model for your Web application.

Phalcon Jumpstart used Phalcon Annotations to mapping model class to table in MySQL database.

For example: the product functionality, the product will have a model containing all the related handling products that access to the database, following the syntax.

<?php
namespace Model;

/**
 * Product
 *
 * Represents a Product
 *
 * @Source('fly_product');
 */
class Product extends \Fly\BaseModel
{
    /**
    * @Column(type="integer", nullable=true, column="u_id")
    */
    public $uid;
    
    /**
    * @Primary
    * @Identity
    * @Column(type="integer", nullable=false, column="p_id")
    */
    public $id;
    
    /**
    * @Column(type="string", nullable=true, column="p_name")
    */
    public $name;
    
    ...

• @Source: declare table name.
• @Column:
  • type: define type of table field.
  • nullable: validate table field is NULL or NOT NULL.
  • column: table field name.

After declare the model like above, you can call model properties without prefix of table (automatic column mapping) field like:

	$myProduct = new \Model\Product();
	$myProduct->name = 'Product One';
	$myProduct->uid = 1;
