我使用Phalcon DevTools(1.2.3)创建了一个简单的Phalcon项目。 现在我想将MongoDB用于数据库。如何正确设置? 我走到这一步(见下面的代码):
<?php
return new \Phalcon\Config(array(
'database' => array(
'adapter' => 'Nosql', //Was 'Mysql', but Nosql is not supported?
'host' => 'localhost',
'username' => 'root',
'password' => '',
'dbname' => 'test',
),
'application' => array(
'controllersDir' => __DIR__ . '/../../app/controllers/',
'modelsDir' => __DIR__ . '/../../app/models/',
'viewsDir' => __DIR__ . '/../../app/views/',
'pluginsDir' => __DIR__ . '/../../app/plugins/',
'libraryDir' => __DIR__ . '/../../app/library/',
'cacheDir' => __DIR__ . '/../../app/cache/',
'baseUri' => 'localhost/',
)
));
<?php
use Phalcon\DI\FactoryDefault,
Phalcon\Mvc\View,
Phalcon\Mvc\Url as UrlResolver,
//Phalcon\Db\Adapter\Pdo\Mysql as DbAdapter, //Do I need this when I use Mongo?
Phalcon\Mvc\View\Engine\Volt as VoltEngine,
Phalcon\Mvc\Model\Metadata\Memory as MetaDataAdapter,
Phalcon\Session\Adapter\Files as SessionAdapter;
/**
* The FactoryDefault Dependency Injector automatically register the right services providing a full stack framework
*/
$di = new FactoryDefault();
/**
* The URL component is used to generate all kind of urls in the application
*/
$di->set('url', function() use ($config) {
$url = new UrlResolver();
$url->setBaseUri($config->application->baseUri);
return $url;
}, true);
/**
* Setting up the view component
*/
$di->set('view', function() use ($config) {
$view = new View();
$view->setViewsDir($config->application->viewsDir);
$view->registerEngines(array(
'.volt' => function($view, $di) use ($config) {
$volt = new VoltEngine($view, $di);
$volt->setOptions(array(
'compiledPath' => $config->application->cacheDir,
'compiledSeparator' => '_'
));
return $volt;
},
'.phtml' => 'Phalcon\Mvc\View\Engine\Php'
));
return $view;
}, true);
/**
* Database connection is created based in the parameters defined in the configuration file
*/
$di->set('mongo', function() use ($config) {
$mongo = new Mongo();
return $mongo->selectDb($config->database->dbname);
});
/**
* If the configuration specify the use of metadata adapter use it or use memory otherwise
*/
$di->set('modelsMetadata', function() {
return new MetaDataAdapter();
});
/**
* Start the session the first time some component request the session service
*/
$di->set('session', function() {
$session = new SessionAdapter();
$session->start();
return $session;
});
我使用文档将标准的mysql数据库连接更改为mongo。 但现在我必须在Config中设置我的数据库适配器,但Nosql似乎不起作用。在尝试创建模型时,DevTools会在终端中抛出此错误:
Error: Adapter Nosql is not supported
当我在配置中为适配器输入'Mysql'并尝试创建模型时,这是我得到的错误:
Error: SQLSTATE[HY000] [2002] No such file or directory
是否需要设置Mysql适配器才能使用Mongo / Nosql?或者我应该为适配器/配置添加其他东西?有任何想法吗?

在 service.php 文件中,您已注册mongo服务
$di->set('mongo', function() {
$mongo = new Mongo();
return $mongo->selectDb("DB_NAME");
}, true);
下面是以下代码行,
$di->set('collectionManager', function(){
return new Phalcon\Mvc\Collection\Manager();
}, true);
完成上述操作后,您需要确保您的模型从\ Phalcon \ Mvc \ Collection
扩展E.g。 Customers.php
class Customers extends \Phalcon\Mvc\Collection
{
public $name;
public $email;
}
完成上述操作后,您可以验证一切是否正常,如下所示
$robot = new Customers();
$robot->email= "abc@test.com";
$robot->name = "XYZ";
if ($robot->save() == false)
{
echo "Could not be Saved!!";
}
else
{
echo "Data Saved!!";
}
您可以将以上代码放在任何Controller-Action中并尝试。
如果一切顺利,您应该能够在MongoDB数据库中看到在Customer集合中创建的一个文档。

$di->set('mongo', function() {
$user = 'blog';
$password = 'blog';
$host = 'localhost';
$port = '27017';
$db = 'blog';
$cn = sprintf('mongodb://%s:%d/%s',$host,$port,$db);
$con = new Mongo($cn,array('username'=>$user,'password'=>$password));
return $con->selectDB($db);
}, true);

As of the latest PhalconPHP,MongoDB似乎只是一个受支持的缓存选项,而不是用作数据库的替代品。

看起来Config组件没有MongoDB适配器,孵化器(https://github.com/phalcon/incubator)中只有MySQL和其他几个(基于文本)。
您仍然可以将MongoDB用于ACL和模型,请参阅https://github.com/phalcon/incubator/tree/master/Library/Phalcon/Acl/Adapter和http://docs.phalconphp.com/en/latest/reference/odm.html#
