Generating a Project Skeleton¶

You can use Phalcon tools to generate pre-defined project skeletons for your applications with Phalcon framework. By default the project skeleton generator will use mod_rewrite for Apache. Type the following command on your web server document root:

$ phalcon create-project store

The above recommended project structure was generated:

You could add the parameter --help to get help on the usage of a certain script:

$ phalcon project --help

Phalcon DevTools (4.0.0)

Help:
  Creates a project

Usage:
  project [name] [type] [directory] [enable-webtools]

Arguments:
  help  Shows this help text

Example
  phalcon project store simple

Options:
 --name=s               Name of the new project
 --enable-webtools      Determines if webtools should be enabled [optional]
 --directory=s          Base path on which project will be created [optional]
 --type=s               Type of the application to be generated (cli, micro, simple, modules)
 --template-path=s      Specify a template path [optional]
 --template-engine=s    Define the template engine, default phtml (phtml, volt) [optional]
 --use-config-ini       Use a ini file as configuration file [optional]
 --trace                Shows the trace of the framework in case of exception [optional]
 --help                 Shows this help [optional]

Accessing the project from the web server will show you:

Generating Controllers¶

The command create-controller generates controller skeleton structures. It's important to invoke this command inside a directory that already has a Phalcon project.

$ phalcon create-controller --name test

The following code is generated by the script:

<?php
declare(strict_types=1);

class TestController extends \Phalcon\Mvc\Controller
{

    public function indexAction()
    {

    }

}

Preparing Database Settings¶

When a project is generated using developer tools. A configuration file can be found in app/config/config.php. To generate models or scaffold, you will need to change the settings used to connect to your database.

Change the database section in your config.php file:

<?php

/*
 * Modified: prepend directory path of current file, because of this file own different ENV under between Apache and command line.
 * NOTE: please remove this comment.
 */
defined('BASE_PATH') || define('BASE_PATH', getenv('BASE_PATH') ?: realpath(dirname(__FILE__) . '/../..'));
defined('APP_PATH') || define('APP_PATH', BASE_PATH . '/app');

return new \Phalcon\Config([
    'database' => [
        'adapter'     => 'Mysql',
        'host'        => 'localhost',
        'username'    => 'root',
        'password'    => '',
        'dbname'      => 'test',
        'charset'     => 'utf8',
    ],
    'application' => [
        'appDir'         => APP_PATH . '/',
        'controllersDir' => APP_PATH . '/controllers/',
        'modelsDir'      => APP_PATH . '/models/',
        'migrationsDir'  => APP_PATH . '/migrations/',
        'viewsDir'       => APP_PATH . '/views/',
        'pluginsDir'     => APP_PATH . '/plugins/',
        'libraryDir'     => APP_PATH . '/library/',
        'cacheDir'       => BASE_PATH . '/cache/',
        'baseUri'        => '/',
    ]
]);

Generating Models¶

There are several ways to create models. You can create all models from the default database connection or some selectively. Models can have public attributes for the field representations or setters/getters can be used.

Options:
 --name=s             Table name
 --schema=s           Name of the schema [optional]
 --config=s           Configuration file [optional]
 --namespace=s        Model's namespace [optional]
 --get-set            Attributes will be protected and have setters/getters [optional]
 --extends=s          Model extends the class name supplied [optional]
 --excludefields=l    Excludes fields defined in a comma separated list [optional]
 --doc                Helps to improve code completion on IDEs [optional]
 --directory=s        Base path on which project is located [optional]
 --output=s           Folder where models are located [optional]
 --force              Rewrite the model [optional]
 --camelize           Properties is in camelCase [optional]
 --trace              Shows the trace of the framework in case of exception [optional]
 --mapcolumn          Get some code for map columns [optional]
 --abstract           Abstract Model [optional]
 --annotate           Annotate Attributes [optional]
 --help               Shows this help [optional]

The simplest way to generate a model for a table called users is:

$ phalcon model users

If your database looks like this:

CREATE TABLE `users` (
  `id` int(10) UNSIGNED NOT NULL,
  `name` varchar(255) NOT NULL,
  `email` varchar(255) NOT NULL,
  `password` char(60) NOT NULL,
  `active` tinyint(1) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

ALTER TABLE `users`
  ADD PRIMARY KEY (`id`),
  ADD KEY `email` (`email`);

ALTER TABLE `users`
  MODIFY `id` int(10) UNSIGNED NOT NULL AUTO_INCREMENT;
COMMIT;

It will result in

<?php

use Phalcon\Validation;
use Phalcon\Validation\Validator\Email as EmailValidator;

class Users extends \Phalcon\Mvc\Model
{

    /**
     *
     * @var integer
     */
    public $id;

    /**
     *
     * @var string
     */
    public $name;

    /**
     *
     * @var string
     */
    public $email;

    /**
     *
     * @var string
     */
    public $password;

    /**
     *
     * @var string
     */
    public $active;

    /**
     * Validations and business logic
     *
     * @return boolean
     */
    public function validation()
    {
        $validator = new Validation();

        $validator->add(
            'email',
            new EmailValidator(
                [
                    'model'   => $this,
                    'message' => 'Please enter a correct email address',
                ]
            )
        );

        return $this->validate($validator);
    }

    /**
     * Initialize method for model.
     */
    public function initialize()
    {
        $this->setSchema("test");
        $this->setSource("users");
    }

    /**
     * Allows to query a set of records that match the specified conditions
     *
     * @param mixed $parameters
     * @return Users[]|Users|\Phalcon\Mvc\Model\ResultSetInterface
     */
    public static function find($parameters = null): \Phalcon\Mvc\Model\ResultsetInterface
    {
        return parent::find($parameters);
    }

    /**
     * Allows to query the first record that match the specified conditions
     *
     * @param mixed $parameters
     * @return Users|\Phalcon\Mvc\Model\ResultInterface
     */
    public static function findFirst($parameters = null)
    {
        return parent::findFirst($parameters);
    }

}

Options for generating different type of model blueprints can be found using

phalcon model --help

Scaffold a CRUD¶

Scaffolding is a quick way to generate some of the major pieces of an application. If you want to create the models, views, and controllers for a new resource in a single operation, scaffolding is the tool for the job.

Once the code is generated, it will have to be customized to meet your needs. Many developers avoid scaffolding entirely, opting to write all or most of their source code from scratch. The generated code can serve as a guide to better understand of how the framework works or develop prototypes. The code below shows a scaffold based on the table users:

$ phalcon scaffold --table-name users

The scaffold generator will build several files in your application, along with some folders. Here's a quick overview of what will be generated:

File	Purpose
`app/controllers/UsersController.php`	The Users controller
`app/models/Users.php`	The Users model
`app/views/layout/users.phtml`	Controller layout for Users
`app/views/products/search.phtml`	View for the action `search`
`app/views/products/new.phtml`	View for the action `new`
`app/views/products/edit.phtml`	View for the action `edit`

When browsing the recently generated controller, you will see a search form and a link to create a new Product:

The create page allows you to create products applying validations on the Products model. Phalcon will automatically validate not null fields producing warnings if any of them is required.

After performing a search, a pager component is available to show paged results. Use the "Edit" or "Delete" links in front of each result to perform such actions.

Web Interface to Tools¶

Also, if you prefer, it's possible to use Phalcon Developer Tools from a web interface. Check out the following screencast to figure out how it works:
