Fetching data through a custom repository in a Twig extension

Question

I\'d like to display new notifications on every page of my symfony 2 webapplication. I was advised to use a Twig Extension for this. I\'ve created a function getFriendReques

Answer 1

The same but with mongo:

in config.yml

services:
    user.twig.extension:
        class: MiProject\CoreBundle\Twig\Extension\MiFileExtension
        arguments:
          doctrine: "@doctrine.odm.mongodb.document_manager"
        tags:
          -  { name: twig.extension }

and in your Twig\Extensions\MiFile.php

doctrine = $doctrine;
    }
    public function getTransactionsAmount($user_id){
    return $results = $this->doctrine
    ->createQueryBuilder('MiProjectCoreBundle:Transaction')             
    ->hydrate(false)
    ->getQuery()            
    ->count();
    }

    Rest of mi code ... 

}
