Symfony 2.8 two database connections - symfony

Question

I need to connect to an external database, I just need to do a simple query in one table so I think I dont need to create an new entity manager. I believe all configurations are set up correctly but I still don't get connected to the new database. So i´m missing something but cant find what, here are my files:
# Doctrine Configuration
doctrine:
dbal:
default_connection: default
connections:
default:
driver: pdo_mysql
host: '%database_host%'
port: '%database_port%'
dbname: '%database_name%'
user: '%database_user%'
password: '%database_password%'
charset: UTF8
# if using pdo_sqlite as your database driver:
# 1. add the path in parameters.yml
# e.g. database_path: '%kernel.root_dir%/data/data.db3'
# 2. Uncomment database_path in parameters.yml.dist
# 3. Uncomment next line:
#path: '%database_path%'
database2:
driver: pdo_mysql
host: '%database2_host%'
port: '%database2_port%'
dbname: '%database2_name%'
user: '%database2_user%'
password: '%database2_password%'
charset: UTF8
orm:
auto_generate_proxy_classes: '%kernel.debug%'
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
parameters:
#Set_Goals Database
database_host: 127.0.0.1
database_port: null
database_name: set_goals
database_user: root
database_password: null
#Database2 Database
database2_host: 127.0.0.1
database2_port: null
database2_name: second
database2_user: root
database2_password: null
Repository:
public function getAccounts(){
$conn = $this->getEntityManager()->getConnection('database2');
$sql = 'SELECT * FROM leme_account';
$stmt = $conn->prepare($sql);
$stmt->execute();
return $stmt->fetchAll();
}
Error:
An exception occurred while executing 'SELECT * FROM leme_account':
SQLSTATE[42S02]: Base table or view not found: 1146 Table 'set_goals.leme_account' doesn't exist
set_goals database is the default connection.
Thanks in advance and sorry if I´m missing something really simple here but I´m new to Symfony and programming in general and I followed the documentation and also some related questions here but can´t make it work.

Answer 1

I think you need to create another entity manager
doctrine:
dbal:
default_connection: default
connections:
default:
driver: pdo_mysql
host: '%database_host%'
port: '%database_port%'
dbname: '%database_name%'
user: '%database_user%'
password: '%database_password%'
charset: UTF8
# if using pdo_sqlite as your database driver:
# 1. add the path in parameters.yml
# e.g. database_path: '%kernel.root_dir%/data/data.db3'
# 2. Uncomment database_path in parameters.yml.dist
# 3. Uncomment next line:
#path: '%database_path%'
database2:
driver: pdo_mysql
host: '%database2_host%'
port: '%database2_port%'
dbname: '%database2_name%'
user: '%database2_user%'
password: '%database2_password%'
charset: UTF8
orm:
auto_generate_proxy_classes: '%kernel.debug%'
naming_strategy: doctrine.orm.naming_strategy.underscore
auto_mapping: true
default_entity_manager: default
entity_managers:
default:
connection: default
database2:
connection: database2
Then in your code
$em = $this->get('doctrine')->getManager();
$em2 = $this->get('doctrine')->getManager('database2');
The documentation mentions a mappings key but I don't know if it is mandatory, especially since you are using auto mapping.
Ref: https://symfony.com/doc/2.8/doctrine/multiple_entity_managers.html

Answer 2

Meanwhile, I found the problem.... it was a newb mistake. I was putting my method inside the repository of the other entity. When I added directly to the controller it worked.
Thanks for your answers.
