Yii2 Can't connect to the MongoDB cluster - php

Question

I try to find out what's wrong on https://github.com/yiisoft/yii2-mongodb, but someone just keeps me the link to docs and official chat. There is no any answer how to connect to the cluster. Please help me to solve this issue, I try a lot and spent last 2 days to solve it, but can't understand why it doesn't connect.
I try to configure yii2-mongodb on my project, installed it using composer, then add
in config/web.php
'mongodb' => [
'class' => '\yii\mongodb\Connection',
'dsn' => 'mongodb://user:password#insta1-shard-00-00-s0vxe.mongodb.net:27017,insta1-shard-00-01-s0vxe.mongodb.net:27017,insta1-shard-00-02-s0vxe.mongodb.net:27017/database?ssl=true&replicaSet=Insta1-shard-0&authSource=admin',
]
and use this model:
<?php
namespace app\models;
use Yii;
use yii\base\Model;
use yii\mongodb\Query;
/**
* BlogContent is the model behind the contact form.
*/
class BlogContent extends Model
{
public function getPostList($page) {
$query = new Query();
// compose the query
$rows = $query->select(['name', 'price', 'title'])
->from('services')->all();
}
}
it should return me all documents from the collection, but it returns to me this stack:
yii\base\UnknownMethodException: Calling unknown method: yii\mongodb\QueryBuilder::build() in /var/www/service/vendor/yiisoft/yii2/base/Object.php:220

I solve this first issue by passing a $db connection to query as an optional argument, but it can't connect anyway. Also, I test connection to MongoDB on my local machine - for a single database it works as need.

Answer 1

The issue was because my php-mongodb has a conflict with php7, after I update it all begin to work as need.
