Symfony4: How to toggle entities using dotenv and multiple Entity Manager? - doctrine

Question

How it is possible through dotenv select different entity path with same name of entities.
Originally, We had application in Symfony 3 for people meetings on events of our organization. Then we decided to offer this application to our partners.
One of the partners asked us to customize the application for them with their data and specifications. We basically created a new instance of Symfony application with copy of database tables (with different prefix), changes in Entities to reflect new db table names, and some translation text changes.
It seems that other partners will follow this trend of customized instances.
Therefore, I am trying to update core application to Symfony 4 and I am trying to use multiple Entity Managers and dotenv to differentiate between partners database tables, as described bellow.
In a nutshell, I am trying to use multiple Entity Manager to switch db table names by prefix.
.env
###> doctrine/doctrine-bundle ###
# Format described at http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/configuration.html#connecting-using-a-url
# For an SQLite database, use: "sqlite:///%kernel.project_dir%/var/data.db"
# Configure your db driver and server_version in config/packages/doctrine.yaml
DATABASE_URL=oci8://user:pass#127.0.0.1:1521/XE
EM_TYPE=OpenAccess
###< doctrine/doctrine-bundle ###
Only in security.yaml working env good
security:
encoders:
App\Entity\%env(EM_TYPE)%\Osoba:
providers:
our_db_provider:
entity:
class: App\Entity\%env(EM_TYPE)%\Osoba
property: username
When i tried get %env(EM_TYPE)% in default_entity_manager, then give error You have requested a non-existent service "doctrine.orm.%env(EM_TYPE)%_entity_manager". doctrine.yaml
parameters:
env(DATABASE_URL): ''
doctrine:
dbal:
default_connection: '%env(EM_TYPE)%'
connections:
MeetingTool:
driver: 'oci8'
charset: UTF8
schema_filter: /^MT_/
url: '%env(resolve:DATABASE_URL)%'
OpenAccess:
driver: 'oci8'
charset: UTF8
schema_filter: /^OA6_/
url: '%env(resolve:DATABASE_URL)%'
orm:
auto_generate_proxy_classes: true
default_entity_manager: '%env(EM_TYPE)%'
entity_managers:
MeetingTool:
connection: MeetingTool
mappings:
Main:
is_bundle: false
type: annotation
dir: '%kernel.project_dir%/src/Entity/MeetingTool'
prefix: 'App\Entity\MeetingTool'
alias: App2
OpenAccess:
connection: OpenAccess
mappings:
App:
is_bundle: false
type: annotation
dir: '%kernel.project_dir%/src/Entity/OpenAccess'
prefix: 'App\Entity\OpenAccess'
alias: OpenAccess
and biggest problem is use, how i targeting right entity here? for example loginController.php
<?php
namespace App\Controller;
use Doctrine\ORM\EntityManagerInterface;
use App\Entity\OpenAccess\LogPrihlaseni;
//use App\Entity\MeetingTool\LogPrihlaseni;
class LoginController extends AbstractController {
private $entityManager;
public function __construct(EntityManagerInterface $entityManager)
{
$this->entityManager = $entityManager;
}
public function logPrihlaseni() {
$log = new LogPrihlaseni();
