phalcon: 官方多模块

目录结构如下

public/index.php:

use Phalcon\Mvc\Router;
use Phalcon\Tag;
use Phalcon\Mvc\Url;
use Phalcon\Mvc\View;
use Phalcon\Mvc\Application;
use Phalcon\DI\FactoryDefault;
use Phalcon\Db\Adapter\Pdo\Mysql as DbAdapter;

// Create a DI
$di = new FactoryDefault();

$di->set('router', function () {

    $router = new Router();

    $router->setDefaultModule("frontend");

    $router->setDefaults(array(
        "namespace" => 'Multiple\Frontend\Controllers',
        "controller" => "Index",
        "action" => "index"
    ));
    //frontend
    $router->add("/:controller", array(
        'module'=>'frontend',
        'controller' => 1,
    ));
    $router->add("/:controller/:action", array(
        'module'=>'frontend',
        'controller' => 1,
        'action'     => 2,
    ));
    $router->add("/:controller/:action/:param", array(
        'module'=>'frontend',
        'controller' => 1,
        'action'     => 2,
        'param'      => 3,
    ));
    //backend
    $router->add("/admin/:controller", array(
        'module'=>'backend',
　　　　　'namespace'=>'Multiple\Backend\Controllers', //　一定要加上，要不然找不到后台
        'controller' => 1,
    ));
    $router->add("/admin/:controller/:action", array(
        'module'=>'backend',
　　　　  'namespace'=>同上,
        'controller' => 1,
        'action'     => 2,
    ));
    $router->add("/admin/:controller/:action/:param", array(
        'module'=>'backend',
        'namespace'=>同上,
        'controller' => 1,
        'action'     => 2,
        'param'      => 3,
    ));

    return $router;
});

try {

    $di['db'] = function(){
        return new DbAdapter(array(
            "host"     => "localhost",
            "username" => "root",
            "password" => "",
            "dbname"   => "demo",
            "charset"  => "utf8"
        ));
    };

    // Setup a base URI so that all generated URIs include the "tutorial" folder
    $di['url'] = function() {
        $url = new Url();
        $url->setBaseUri('/');
        return $url;
    };

    // Handle the request
    $application = new Application($di);
    //加入模块分组配置
    $application->registerModules(
        array(
            'frontend' => array(
                'className' => 'Multiple\Frontend\Module',
                'path'      => '../app/frontend/Module.php',
            ),
            'backend'  => array(
                'className' => 'Multiple\Backend\Module',
                'path'      => '../app/backend/Module.php',
            )
        )
    );
    echo $application->handle()->getContent();
} catch (Exception $e) {
     echo "Exception: ", $e->getMessage();
}

　　

frontend/module.php(backend/module.php的配置跟它的雷同):

<?php
namespace Multiple\Frontend;

use Phalcon\Loader,
    Phalcon\Mvc\Dispatcher,
    Phalcon\Mvc\View,
    Phalcon\Mvc\ModuleDefinitionInterface;

class Module implements ModuleDefinitionInterface {

    public function registerAutoloaders( \Phalcon\DiInterface $di = NULL)
    {
        $loader = new Loader();
        $loader->registerNamespaces(array(
            'Multiple\Frontend\Controllers' => __DIR__ . '/controllers/',
            'Multiple\Models' => __DIR__ . '/../models/'
        ))->register();
        $loader->registerDirs(
            array(
                'modelsDir'      => '../app/models/',
            )
        )->register();

    }

    public function registerServices( \Phalcon\DiInterface $di)
    {
        $di->set("dispatcher", function(){
            $dispatcher = new Dispatcher();
            $dispatcher->setDefaultController("Multiple\Frontend\Controllers");
            return $dispatcher;
        });

        $di->set("view", function(){
            $view = new View();
            $view->setViewsDir("../app/frontend/views/");
            $view->registerEngines(array(
                '.phtml' => 'Phalcon\Mvc\View\Engine\Php'
            ));
            return $view;
        });

    }
}

　　

frontend/controllers/indexController.php:

namespace Multiple\Frontend\Controllers;
//use Multiple\Models\Level;
class IndexController extends \Phalcon\Mvc\Controller {

    public function indexAction()
    {
　　　　$level = Level::findFirst("id = 10");
        $this->view->pick('index/index');
    }

}

　　models/Level.php

//namespace Multiple\Models;
class Level extends \Phalcon\Mvc\Model
{

    public $lid;
    public $name;
    public $description;
    public $create_time;

    public function beforeCreate()
    {
        if( is_null($this->create_time) )
        {
            $this->create_time = time();
        }

    }
}

　　

那么多模块下，如何分页的，如果直接用->from(表名)，报错找不到此类，此时要引用model类的全命名空间名称如下：

Multiple\Models\Level(表)。

namespace Multiple\Backend\Controllers;
use Phalcon\Paginator\Adapter\QueryBuilder;
class IndexController extends ControllerBase {

    public function initialize()
    {
        parent::initialize();

    }

    public function indexAction()    {

        $builder = $this->modelsManager->createBuilder()
            ->columns("id,username,name,email")
            ->from('Users')
            ->orderBy("id ASC")
            ->getQuery()
            ->execute();

        $paginator = new QueryBuilder(array(
            "builder"=>$builder,
            "limit"=>10,
            "page"=>1
        ));

        $this->view->setTemplateBefore('base');
        $this->view->pick('index/index');
    }

}
