Phalcon MongoDB 数据库

  • 772

php7.0. Phalcon 3.2.MongoDB 3.2.14

我想连接到数据库，但 Phalcon 文档描述了通过 MongoClient() 建立连接并仅通过它工作，尽管它在很久以前就已经过时并且在 7.0 中通常被弃用。我怎样才能使 Phalcon 朋友变得现代和舒适\MongoDB\Driver\Manager()？因为services.php最起码我是这样设置的，貌似不骂人，代码是这样的：

/**
* MongoDB connection
*/
$di->set( "mongo", function () {
       $config = $this->getConfig();

        $db_string = sprintf( 'mongodb://%s:%s/%s', $config->mongodb->host, $config->mongodb->port, $config->mongodb->database );

        if( isset( $config->mongodb->user ) AND isset( $config->mongodb->password ) ) {
            $db_string = sprintf( 'mongodb://%s:%s@%s:%s/%s',
                $config->mongodb->user,
                (string)$config->mongodb->password,
                $config->mongodb->host,
                (string)$config->mongodb->port,
                $config->mongodb->database );
       }

        try {
            return new \MongoDB\Driver\Manager( $db_string );
        } catch (MongoConnectionException $e) {
            die( 'Failed to connect to MongoDB '.$e->getMessage() );
        }
    },
    true
);

但他不喜欢模特。我写信给app/models/User.php：

use Phalcon\Mvc\Collection;

class User extends Collection
{
    public function initialize()
    {
        $this->setSource('users');
    }
}

我在控制器中调用：

class IndexController extends ControllerBase
{
    public function indexAction()
    {
        echo User::count();
    }
}

是这样写的：

Call to undefined method ::selectcollection()
#0 [internal function]: Phalcon\Mvc\Collection::_getGroupResultset(Array, Object(User), Object(MongoDB\Driver\Manager))
#1 /var/www/testing/app/controllers/IndexController.php(8): Phalcon\Mvc\Collection::count()
#2 [internal function]: IndexController->indexAction()
#3 [internal function]: Phalcon\Dispatcher->callActionMethod(Object(IndexController), 'indexAction', Array)
#4 [internal function]: Phalcon\Dispatcher->_dispatch()
#5 [internal function]: Phalcon\Dispatcher->dispatch()
#6 /var/www/testing/public/index.php(42): Phalcon\Mvc\Application->handle()
#7 {main}

如何取胜？

    首先，我使用 composer 安装了 Phalcon 孵化器到我的 vendor 目录中：

    composer require phalcon/incubator

    然后我确保加载供应商库：

    include_once SITE_ROOT . 'vendor/autoload.php';

    然后我使用\Phalcon\Db\Adapter\MongoDB\Client()发现vendor/phalcon/incubator/Library/Phalcon/Db/Adapter/MongoDB/Client.php

    在services.php：

    $di->setShared('mongo', function () use ($config) {
    $mongo = new \Phalcon\Db\Adapter\MongoDB\Client();
    return $mongo->selectDatabase($config->mongodb->dbname);
});

    然后确保我的 MongoCollection 扩展\Phalcon\Mvc\MongoCollection( vendor/phalcon/incubator/Library/Phalcon/Mvc/MongoCollection.php)。

    models/MyCollectionStats.php:

    <?php

namespace Common\Models;

class MyCollectionStats extends \Phalcon\Mvc\MongoCollection
{...

    答案就在这里。希望这对将来的人有帮助:)
