mongodb

[prohorsev]

Tell me please how to use mongodb? I installed phalcon, devtools, incubator 3.4, mongodb 4.4. Where can I insert settings (dbname, login, password), config.php? How should I use incubator adapter, services.php? Where can I insert php class Collection, which extends MongoCollection, in models? Or any other ways?

Hello, v3.4 is deprecated version, use v4.1 instead.

Also use updated mongo-db composer package - https://github.com/phalcon/incubator-mongodb
composer require phalcon/incubator-mongodb

Code example:

$di->setShared('mongo', function () {
        $mongo = new Client("mongodb://mongo-db-url:27017");

        return $mongo->selectDatabase("hello_world");
    });

    // Registering the mongoDB CollectionManager service
    $di->setShared('collectionsManager', function () {
        return new MongoDBCollectionManager();
    });

Collection

<?php

use Phalcon\Incubator\MongoDB\Mvc\Collection;

class UsersCollection extends Collection
{
    public function onConstruct(): void
    {
        $this->setSource('users');
        $this->useImplicitObjectIds(false);
    }
}

Controller

<?php

use Phalcon\Mvc\Controller;
use Phalcon\Mvc\View;
use Phalcon\Mvc\Model\Resultset;

class MongoController extends Controller
{
    public function indexAction()
    {
        return UsersCollection::findFirst([
            'conditions' => [
                '_id' => mt_rand(1, 10000),
            ],
            'projection' => [
                //'id' => 0,
            ],
        ]);
    }

Hello. Insert it in services.php:

$di->setShared('mongo', function () {
        $mongo = new Client("mongodb://mongo-db-url:27017");

        return $mongo->selectDatabase("test");
    });

    // Registering the mongoDB CollectionManager service
    $di->setShared('collectionsManager', function () {
        return new MongoDBCollectionManager();
    });

Client and MongoDBCollectionManager are unknown classes.
Insert it in library\test\TestCollection.php:

<?php

use Phalcon\Incubator\MongoDB\Mvc\Collection;

class TestCollection extends Collection
{
    public function onConstruct(): void
    {
        $this->setSource('TestCollection');
        $this->useImplicitObjectIds(false);
    }
}

Insert it in MongoController.php:

<?php

use Phalcon\Mvc\Controller;
use Phalcon\Mvc\View;
use Phalcon\Mvc\Model\Resultset;

class MongoController extends Controller
{
    public function indexAction()
    {
        return TestCollection::findFirst(['conditions' => [
            '_id' => mt_rand(1, 10000),
        ],
            'projection' => [
                //'id' => 0,
            ],]);
    }
}

Go to page /mongo. Error 500. What's wrong?
Mongodb:

Thank you. Excellent repository. How can I debug mongodb connection? It still doesn't work. Should I enable access control via installing mongodb server https://docs.mongodb.com/manual/tutorial/enable-authentication/ ?

Problem was:

• composer require mongodb/mongodb
• isert in index.php:

include __DIR__ . '/../vendor/autoload.php';
