Using Mongodb

Yii 2.0 General Discussions

Hello, I’m trying to understand how to use mongodb , but get troubles. There are so many different approaches to interact with mongo…

From php manual:




// connect

$connection = new MongoClient();


// select a database

$database = $connection->my_mongo_db;


// select a collection (analogous to a relational database's table)

$collection = $database->customer;


// add a record

$collection->insert([ 'name' => 'John Smith', 'status' => 1]);

In the yii\mongodb\Connection.php source code


 $connection = new \yii\mongodb\Connection([

     'dsn' => $dsn,

]);

$connection->open();

$database = $connection->getDatabase('my_mongo_db');

$collection = $database->getCollection('customer');

$collection->insert(['name' => 'John Smith', 'status' => 1]);


//or


$collection = Yii::$app->mongodb->getCollection('customer');

$collection->insert(['name' => 'John Smith', 'status' => 1]);

From examples above I can’t understand additional methods: getDatabase and getCollection. From my mind native methods make the same work and look better. Eg:




//Yii

$database = $connection->getDatabase('my_mongo_db');

$collection = $database->getCollection('customer');

vs

//PHP Mongodb ext

$database = $connection->my_mongo_db;

$collection = $database->customer;

Could I use these approaches (http://php.net/manual/ru/mongo.sqltomongo.php) or I should use the yii\mongodb\Query instead? Or maybe I can mix them?

I want to get work something like this:




$collection = Yii::$app->mongodb->database_name->collection_name;


//or

$connection = Yii::$app->mongodb->open();

$collection = $connection->database_name->collection_name;

If you want to be able to use a lot of Yii features I recommend use it as ORM

just extend your model class from yii\mongodb\ActiveRecord

override collectionName()and attributes() and that’s it.

also don’t forget set mongodb dsn in config
