Why can I use entity manager in controller and not in Command? - postgresql

Question

I have created a service for getting the entity manager in a command
I don't understand why I can use the entity manager in regular Controller and not in my Command.
I have declared my service in "service.yml"
common.doctrine:
class: AppBundle\Services\GetDoctrineService
arguments: [ '#doctrine.orm.entity_manager' ]
public: true
I wrote it in "GetDoctrineService.php"
<?php
namespace AppBundle\Services;
use Doctrine\ORM\EntityManager;
class GetDoctrineService
{
protected $em;
public function __construct(\Doctrine\ORM\EntityManager $em)
{
$this->em = $em;
}
public function getRepository(string $repo) {
return $this->em->getRepository($repo);
}
}
In my command, I am importing it and calling it in the "Command way"
$em = $this->getApplication()->getKernel()->getContainer()->get('common.doctrine');
$foo = $em->getRepository(Entity::FOO)->findAll();
I changed the db host to "localhost" in "parameters.yml"
# This file is auto-generated during the composer install
parameters:
#database_host: db-name
database_host: localhost
When I installed postgres with a command, the file "pg_hba.conf" wasn't created (I am working with Ubuntu)
I have this error while i use my command :
Message: "An exception occured in driver: SQLSTATE[08006] [7] could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432?"

Answer 1

The problem was in the configuration files:
using 'localhost' was a mistake: we should have use the dn-name for the host
